Purpose: Time to surgery from admission is one of the few variables known to influence outcome after a hip fracture. We reviewed our hip fracture database to determine correlation between delays to surgery and mortality in our elderly hip fracture population., Methods: Data on all hip fracture patients admitted to a large district hospital were prospectively collected between January 1989 and August 2021. Time of the injury, time of admission and time of surgery were recorded. Patients over 60 years old with a hip fracture requiring operative management were included. Patients with pathological fractures, those managed conservatively, and patients delayed for medical reasons were excluded. Surgical timing categories were divided into; under 12 h, 12-24 h, 24-72 h and over 72 h., Results: Time from admission to surgery was recorded for 10,659 patients, of these time of fall was available for 10,346 patients. Mean age was 82.2 years (sd 8.39) for the cohort and 30 day mortality was 6.20%. Odds of 30-day mortality was 1.43 (CI 1.057-1.988, p = 0.025) for delay to surgery from admission of over 12 h compared to under 12 h. Odds ratios for 30-day mortality were not significant at any other time threshold. The odds of 30-day mortality for delay to surgery from time of fall were 1.550 (CI 1.026-2.459, p = 0.048) at the 12 h threshold., Conclusion: This is the largest prospective study to date in elderly patients with hip fractures demonstrating a statistically significant increase in 30-day mortality with a delay to surgery over 12 h., (© 2024.

Purpose: Rehabilitation after hip fracture surgery is crucial for improving physical function. Additional rehabilitation over the weekend or after working hours is reportedly associated with improved physical function; however, this may not apply to an aging population, including patients aged > 90 years. This study aimed to investigate the association between additional weekend rehabilitation and functional outcomes in different age groups., Methods: This study analyzed a cohort of patients aged ≥ 60 years who had hip fractures and were operated on from 2010 to 2018. Data were extracted from a nationwide multicentre database. Functional outcomes at discharge were compared between patients who underwent rehabilitation on weekdays only and those who underwent rehabilitation on both weekdays and weekends. The patient groups were selected using propensity score matching analysis. Furthermore, a subgroup-analysis was conducted on patients in their 60 s, 70 s, 80 s, and 90 s., Results: A total of 390,713 patients underwent surgery during the study period. After matching, each group comprised 129,583 pairs of patients. Patients who underwent weekend rehabilitation exhibited improved physical function in transferring, walking, and stair climbing at discharge, as compared with patients who did not (odds ratio [95% confidence interval]: 1.17 [1.15-1.19], 1.17 [1.15-1.2], and 1.06 [1.03-1.08], respectively). In subgroup analysis, except for stair climbing, the positive association between weekend rehabilitation and patient function was observed across all age groups., Conclusion: Weekend rehabilitation was significantly associated with improved physical function. Given the limited healthcare resources, high-demand activities such as stair climbing may be reserved for younger age groups to optimise rehabilitation therapy., (© 2024.

Objectives: This study aimed to examine the impact of prefracture cognitive impairment (CI) severity and postoperative delirium on recovery after hip fracture surgery in older patients., Design: Prospective study with a 1-year follow-up., Setting and Participants: We included 355 patients aged ≥80 years from 2 acute hospitals in Japan., Methods: Barthel Index (BI) ambulation scores were assessed prefracture and at 1, 3, 6, and 12 months postoperatively. The score at each time point minus the prefracture score was used as the ambulation recovery variable. The 21-item Dementia Assessment Sheet for the Community-based Care System (DASC-21) and Confusion Assessment Method were used to assess CI severity and delirium, respectively. The impacts of CI severity and delirium on recovery at 1 month and by 12 months postoperatively were examined. Linear multiple regression and linear mixed effects models were used., Results: BI ambulation scores remained the same or improved from prefracture levels in 26.8%, 34.4%, 33.0%, and 30.4% of patients at 1, 3, 6, and 12 months, respectively. Ten patients (2.8%) had fall-related hip fractures, 20 (5.6%) were rehospitalized, and 43 (12.1%) died during this period. Although DASC-21 CI severity significantly affected the recovery both at 1 month and by 12 months postoperatively [standardized β (Stdβ) = -0.39, P < .0001, and Stdβ = -0.37, P < .0001, respectively], delirium did not. Other variables affecting recovery by 12 months postoperatively included prefracture BI ambulation scores, Mini Mental State Examination scores, age, fracture type, place of residence, and time., Conclusions and Implications: Postoperative ambulation recovery, excluding the effect of death and other poor outcomes, is influenced by prefracture CI severity, and the presence of delirium itself may not be the moderating variable. These results emphasize the importance of treatment planning based on prefracture CI severity and indicate that assessments such as the DASC-21 may be useful in implementing such a plan., Competing Interests: Disclosure The authors declare no conflicts of interest., (Copyright © 2024 The Authors.

Periprosthetic femoral hip fractures are subject to an increasing incidence and are often considered to be related to osteoporosis. However, there are no available studies that have determined the frequency of osteoporosis in affected patients using gold standard dual-energy X-ray absorptiometry (DXA). In this retrospective comparative study, we analyzed the DXA results of 40 patients with periprosthetic femoral hip fractures who were treated surgically in our department. DXA measurements were performed at the total hip and the lumbar spine to determine bone mineral density T-scores. Data were compared to two age-, sex-, and BMI-matched control groups in which patients underwent DXA prior to aseptic revision surgery for other causes or primary THA (consisting of 40 patients each). The mean T-score in the periprosthetic fracture cohort was significantly lower (- 1.78 ± 1.78) than that of the aseptic revision (- 0.65 ± 1.58, mean difference - 1.13 [95% CI - 1.88 to - 0.37]; p = 0.001) and the primary THA cohort (- 0.77 ± 1.34, mean difference - 1.01 [95% CI - 1.77 to - 0.26]; p = 0.005). Accordingly, osteoporosis was detected more frequently (45%) in the fracture cohort compared to patients undergoing aseptic revision (12.5%) and primary THA (10%). In conclusion, almost half of the patients with periprosthetic femoral hip fractures have osteoporosis according to DXA measurements. A regular assessment of bone health in THA enables identification of patients with osteoporosis who likely benefit from initiation of osteoporosis medication and cemented stem fixation., (© 2024.

Background: Prolonged operative duration is an independent risk factor for surgical complications in numerous subspecialties. However, associations between adverse events and operative duration of hip fracture fixation in older adults have not been well-quantified. This study aims to determine if prolonged operative duration of hip fracture surgery is related to adverse outcomes. We hypothesized that patients with high operative durations experience greater rates of 30-day complications., Methods: The American College of Surgeons National Surgical Quality Improvement Program database was retrospectively reviewed to identify older adults (55 years and above) who underwent hip fracture fixation between 2015-2019. Prolonged operative duration was defined as >75th percentile, and cases were matched using propensity scores based on demographic, surgical, and comorbidity factors. Univariate differences in adverse events (including readmission, reoperation, mortality, and organ-system complications) were analyzed. Multivariable mixed-effects logistic regression analyses were completed for statistically significant events., Results: A total of 8827 case-control pairs were identified for comparison. Rates of superficial surgical site infection (SSI) (p= 0.022), any SSI (p= 0.032), and any complication (p < 0.001) were elevated in those with prolonged surgical duration in univariate analyses. In multivariable models, prolonged operative time was associated with superficial SSI (OR 1.50, p= 0.019), any SSI (OR 1.35; p= 0.029) and any complication (OR 1.58; p < 0.001). In subgroup analyses, all findings persisted for IMN with operative time associated with superficial SSI (OR 1.98, p= 0.012), any SSI (OR 1.71; p= 0.019), and any complication (OR 1.84; p < 0.001). Operative time was associated only with any complication for hemiarthroplasty/internal fixation and sliding hip screw (OR 1.27 and 1.89, respectively; p < 0.001)., Conclusion: Our study demonstrates that duration of surgery is an independent risk factor for superficial SSI, any SSI, and any complication. Notably, our findings suggest that high operative durations may be most concerning for SSIs in IMN fixation, which is currently the most common choice for hip fracture fixation in the US. However, the rate of any complication is significantly elevated when surgical duration is prolonged, regardless of surgery type., Competing Interests: Declaration of competing interest The authors do not have any conflicts of interest to declare for this investigation., (Copyright © 2024.

Importance: Institutions have adopted protocol-driven standardized hip fracture programs (SHFPs). However, concerns persist regarding bias in adherence to guideline-concordant care leading to disparities in implementing high-quality care for patients recovering from surgery for hip fracture., Objective: To assess disparities in the implementation of guideline-concordant care for patients after hip fracture surgery in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Targeted Hip Fracture (THF) Database., Design, Setting, and Participants: This cross-sectional study was conducted using the ACS-NSQIP THF database from 2016 to 2021 for patients aged 65 years and older with hip fractures undergoing surgical fixation. Care outcomes of racial and ethnic minority patients (including American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Pacific Islander, or multiple races and Hispanic ethnicity) were compared with non-Hispanic White patients via risk difference, stratified by care institution SHFP status. Modified Poisson regression was used to measure interactions. Statistical analysis was performed from November 2022 to June 2024., Main Outcomes and Measures: The primary outcomes of interest encompassed weight-bearing as tolerated (WBAT) on postoperative day 1 (POD1), venous thromboembolism (VTE) prophylaxis, bone-protective medication, and the presence of SHFP at the institution., Results: Among 62 194 patients (mean [SD] age, 82.4 [7.3] years; 43 356 [69.7%] female) who met inclusion criteria and after multiple imputation, 11.2% (95% CI, 10.8%-11.5%) were racial and ethnic minority patients, 3.3% (95% CI, 3.1%-3.4%) were Hispanic patients, and 92.0% (95% CI, 91.7%-92.2%) were White. Receiving care at an institution with an SHFP was associated with improved likelihood of receiving guideline-concordant care for all patients to varying degrees across care outcomes. SHFP was associated with higher probability of being WBAT-POD1 (risk difference for racial and ethnic minority patients, 0.030 [95% CI, 0.004-0.056]; risk difference for non-Hispanic White patients, 0.037 [95% CI, 0.029-0.45]) and being prescribed VTE prophylaxis (risk difference for racial and ethnic minority patients, 0.066 [95% CI, 0.040-0.093]; risk difference for non-Hispanic White patients, 0.080 [95% CI, 0.071-0.089]), but SHFP was associated with the largest improvements in receipt of bone-protective medications (risk difference for racial and ethnic minority patients, 0.149 [95% CI, 0.121-0.178]; risk difference for non-Hispanic White patients, 0.181 [95% CI, 0.173-0.190]). While receiving care at an SHFP was associated with improved probability of receiving guideline-concordant care in both race and ethnicity groups, greater improvements were seen among non-Hispanic White patients compared with racial and ethnic minority patients., Conclusions and Relevance: Older adults who received care at an institution with an SHFP were more likely to receive guideline-concordant care (bone-protective medication, WBAT-POD1, and VTE prophylaxis), regardless of race and ethnicity. However, the probability of receiving guideline-concordant care at an institution with an SHFP increased more for non-Hispanic White patients than racial and ethnic minority patients.

Background: Various factors contribute to the development of mortality and morbidity in hip fracture surgeries. This study aims to investigate the effects of modifiable factors such as the type of anesthesia, anesthesia management, surgical method, and timing of surgery on 30-day mortality rates, intensive care unit admissions, and complications., Methods: A total of 400 patients who underwent hip fracture surgery between January 2021 and December 2023 at a Training and Research Hospital were retrospectively analyzed. Patients were divided into two groups: those followed in the ward, named Group 1 (n=304), and those in the intensive care unit, named Group 2 (n=96). Recorded data included demographic characteristics, American Society of Anesthesiologists (ASA) physical status scores, types of comorbidities, anesthesia type, surgical method, surgical delay time, duration of surgery, blood transfusion requirements, and complications., Results: Patients in Group 2 had higher mean age, comorbidity, and mortality rates compared to Group 1 (p<0.001). In terms of types of comorbidities, the rate of intensive care unit admission was higher in patients with coronary artery disease and chronic renal failure (p<0.001). Mean surgical delay and length of hospital stay were also higher in Group 2 (p<0.001). In multivariate logistic regression analysis, age (p<0.001, Odds Ratio [OR]=1.91, Confidence Interval [CI]=1.046-1.137), ASA score (p<0.001, OR=3.872, CI=1.913-7.838), duration of surgical delay (p<0.001, OR=2.029, CI=1.365-3.017), surgical method (p=0.003, OR=2.003, C=1.258-3.188), and length of hospital stay (p=0.006, OR=1.147, CI=1.04-1.266) were determined as predictive factors for 30-day mortality., Conclusion: This study found that age, ASA classification, length of hospital stay, surgical method, and surgical delay were predictive factors for both morbidity and mortality. Among these, surgical delay time appears to be a modifiable parameter when all factors are considered.

Background and Objective: Postoperative pneumonia (POP) is the leading cause of death among patients with hip fractures. Simple and cost-effective markers can be used to assess the risk of these patients. This study aims to investigate the association between POP and preoperative albumin-globulin ratio (AGR) in patients with hip fractures., Methods: A retrospective analysis was conducted on data from 1417 hip fracture patients admitted to the Department of Orthopaedics at the hospital. Generalized additive and logistic regression models were used to determine both linear and non-linear associations between preoperative AGR and POP. A two-piece regression model was employed to determine the threshold effect., Results: The study included 1417 participants, with a mean age of 77.57 (8.53) years and 26.96% (382/1417) male patients. The prevalence of POP was 6.21%. Following full covariate adjustment, each unit increase in AGR was associated with a 79% reduction in the incidence of POP (OR, 0.23; 95% CI: 0.08-0.63; P = 0.0046). The inflection point was found to be 1.33 using a two-piecewise regression model. For each unit increase in AGR on the left side of the inflection point, the incidence of POP decreased by 93% (OR, 0.07; 95%CI: 0.02-0.34; P = 0.0010). However, there was no statistically significant correlation on the right side of the inflection point (OR, 0.84; 95% CI: 0.17-4.10; P = 0.8287)., Conclusion: There exists a non-linear association between preoperative AGR and the incidence of POP in elderly hip fracture patients. When AGR is less than 1.33, the incidence of POP is negatively correlated with AGR. However, there is no correlation when AGR is greater than 1.33., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024 Elsevier Ltd.

Purpose: Treatment with direct-acting oral anticoagulants (DOACs) is increasing among hip-fracture patients, with accompanying safety concerns regarding spinal anesthesia (SA). The aim of this study was to investigate if DOAC use is associated with increased waiting time before surgery, increased mortality, or other adverse events., Methods: Registry data on surgically treated hip-fracture cases at a single hospital between 2015 and 2021 were analyzed. Multivariable regression analyses were performed with DOAC-status and choice of anesthesia as exposures, and waiting time, length of stay, transfusion, and mortality as outcomes., Results: 2885 cases were included, 467 patients (16%) were using DOACs. DOAC users were older (86.3 vs. 82.2 years, p < 0.001), had a higher Charlson Comorbidity Index (2.1 vs. 1.5, p < 0.001) and had longer median time to surgery than non-DOAC cases (36 h vs 17 h, p < 0.001). General anesthesia (GA) was used in 19.3% of DOAC patients and in 3.0% of non-DOAC patients. DOAC-patients had an increased risk of one-month mortality (Adjusted Odds Ratio (AOR) 1.6 (1.1-2.3)) and one-year mortality (AOR 1.4 (1.1-1.8)). There were no differences in risk of blood transfusion. Patients on DOAC operated under GA had a lower risk of one-year mortality (AOR 0.5 (0.3-0.9)), but a similar one-month mortality to DOAC-patients operated under SA., Conclusion: DOAC users had a longer waiting time to surgery, indicating postponement of surgery due to concerns of the safety of SA. The clinical practice should be changed to allow earlier surgery for DOAC patients., (© 2024. The Author(s).)

A retired oncologist describes the unexpected death of his wife, Claudia, who spent 25 years as head of the geriatrics service of a major VA hospital. The couple drew comfort in their orchestration of a "good death"; nevertheless they understood that her death was hastened by a number of missteps. In the 2 months following a hip fracture, a chain of complications that required five surgical interventions led to massive hemorrhage from necrotizing esophagitis. Claudia lacked resilience to recover from a sequence of traumas sustainable by a younger person-but even the most experienced geriatrician might not have identified or even suspected her risk. Despite multiple well-controlled comorbidities Claudia was active and independent. She exercised daily and traveled extensively. She did not fit the profile of a frail or vulnerable person, according to assessing instruments in current use. According to the e-prognosis calculator, her mortality risk was 10% lower than that of women her age. It is not surprising, nor deplorable, that after Claudia developed mild dysphagia, a gastroenterologist put off an EGD, awaiting a cardiac consult. That delay, however, proved fatal. Had the procedure been performed as soon as possible, it would have revealed esophagitis caused by a hiatal hernia, signaling need for different medications and prompt treatment. This might have prevented the terminal hemorrhage. The first important lesson from this case is that for an older patient with multiple comorbidities, even under control, delayed treatment is treatment denied. Current evaluation instruments are unable to spot critical resilience reductions in functional seniors. Inadequate pain management, premature discharge after surgery, and poor communication also contributed to the death. The second important lesson is that older patients, even when they are medical doctors, would benefit from a trained advocate to help them navigate the medical system., (© 2024 The Authors.

Introduction: Approximately 20 % of femoral fragility fracture patients take anticoagulants, typically warfarin or Direct Oral AntiCoagulant (DOAC). These can impact timing of surgery affecting patient survival. Due to several possible approaches and numerous factors to consider in the preoperative workup of anticoagulated patients, potential for variations in clinical practice exist. Some hospitals employ dedicated anticoagulation management protocols to address this issue, and to improve time to surgery. This study aimed to determine the proportion of hospitals with such protocols, compare protocol guidance between hospitals, and evaluate the effectiveness of protocols in facilitating prompt surgery., Methods: Data was prospectively collected through a collaborative, multicentre approach involving hospitals across the UK. Femoral fragility fracture patients aged ≥60 years and admitted to hospital between 1 st May to 31 st July 2023 were included. Information from dedicated anticoagulation management protocols were collated on several domains relating to perioperative care including administration of reversal agents and instructions on timing of surgery as well as others. Logistic regression was used to evaluate effects of dedicated protocols on time to surgery., Results: Dedicated protocols for management of patients taking warfarin and DOACs were present at 41 (52.6 %) and 43 (55.1 %) hospitals respectively. For patients taking warfarin, 39/41 (95.1 %) protocols specified the dose of vitamin k and the most common was 5 milligrams intravenously (n=21). INR threshold values for proceeding to surgery varied between protocols; 1.5 (n=28), 1.8 (n=6), and 2 (n=6). For patients taking DOACs, 35/43 (81.4 %) and 8/43 (18.6 %) protocols advised timing of surgery based on renal function and absolute time from last dose respectively. Analysis of 10,197 patients from 78 hospitals showed fewer patients taking DOACs received surgery within 36 h of admission at hospitals with a dedicated protocol compared to those without (adjusted OR 0.73, 95% CI 0.54-0.99, p=0.040), while there were no differences among patients taking warfarin (adjusted OR 1.64, 95% CI 0.75-3.57, p=0.219)., Conclusions: Around half of hospitals employed a dedicated anticoagulation management protocol for femoral fragility fracture patients, and substantial variation was observed in guidance between protocols. Dedicated protocols currently being used at hospitals were ineffective at improving the defined targets for time to surgery., Competing Interests: Declaration of competing interest WE is the Surgical lead of the National Hip Fracture Database of England and Wales.

Background: The association between allogenic blood transfusions and all-cause mortality in surgically treated hip fracture patients with perioperative transfusion (STHFPT) remained unknown. The authors aim to introduce transfusion-related factors, new variables to develop, and validate models to predict mortality in these patients., Methods: A prospective multicenter cohort study was conducted with STHFPT hospitalized during January 2018 and June 2021. The database was divided into training cohort and validation cohort in a ratio of 70-30% using the randomization method. All participants received a minimum of 2-year follow-up and all participants' overall and eight time-specific survival status were recorded. Prediction models were developed using multivariate logistic regression and Cox regression for variable selection. Model performance was measured by determining discrimination, calibration, overall model performance or precision, and utility. Sensitivity analyses were performed to test robustness of the results., Results: A total of 7074 consecutive patients were prospectively screened and assessed for eligibility to participate. Finally, 2490 patients met our inclusion and exclusion criteria and 1743 (70%) patients were randomized to the training cohort and 747 (30%) to the validation cohort. The median duration of follow-up was 38.4 months (IQR 28.0-62.0). Our novel models highlight that preoperative transfusion is of significance for short-term mortality while mid-term outcomes are predominantly determined by severe complications, pulmonary complications, and advanced age. Our models showed high discriminative power, good calibration, and precision for mortality prediction in both training and validation cohorts, especially in short-term mortality prediction., Conclusions: The authors introduce transfusion-related factors, new variables to develop, and validate models to predict mortality with STHFPT. The models can be further tested and updated with the ultimate goal of assisting in optimizing individual transfusion strategy., (Copyright © 2024 The Author(s).

Background: In-hospital mortality following hip fractures is a significant concern, and accurate prediction of this outcome is crucial for appropriate clinical management. Nonetheless, there is a lack of effective prediction tools in clinical practice. By utilizing artificial intelligence (AI) and machine learning techniques, this study aims to develop a predictive model that can assist clinicians in identifying geriatric hip fracture patients at a higher risk of in-hospital mortality., Methods: A total of 52 707 geriatric hip fracture patients treated with surgery from 90 hospitals were included in this study. The primary outcome was postoperative in-hospital mortality. The patients were randomly divided into two groups, with a ratio of 7:3. The majority of patients, assigned to the training cohort, were used to develop the AI models. The remaining patients, assigned to the validation cohort, were used to validate the models. Various machine learning algorithms, including logistic regression (LR), decision tree (DT), naïve bayesian (NB), neural network (NN), eXGBoosting machine (eXGBM), and random forest (RF), were employed for model development. A comprehensive scoring system, incorporating 10 evaluation metrics, was developed to assess the prediction performance, with higher scores indicating superior predictive capability. Based on the best machine learning-based model, an AI application was developed on the Internet. In addition, a comparative testing of prediction performance between doctors and the AI application., Findings: The eXGBM model exhibited the best prediction performance, with an area under the curve (AUC) of 0.908 (95% CI: 0.881-0.932), as well as the highest accuracy (0.820), precision (0.817), specificity (0.814), and F1 score (0.822), and the lowest Brier score (0.120) and log loss (0.374). Additionally, the model showed favorable calibration, with a slope of 0.999 and an intercept of 0.028. According to the scoring system incorporating 10 evaluation metrics, the eXGBM model achieved the highest score (56), followed by the RF model (48) and NN model (41). The LR, DT, and NB models had total scores of 27, 30, and 13, respectively. The AI application has been deployed online at https://in-hospitaldeathinhipfracture-l9vhqo3l55fy8dkdvuskvu.streamlit.app/ , based on the eXGBM model. The comparative testing revealed that the AI application's predictive capabilities significantly outperformed those of the doctors in terms of AUC values (0.908 vs. 0.682, P <0.001)., Conclusions: The eXGBM model demonstrates promising predictive performance in assessing the risk of postoperative in-hospital mortality among geriatric hip fracture patients. The developed AI model serves as a valuable tool to enhance clinical decision-making., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

Hip fracture is a common injury in older adults; however, the optimal timing of surgical treatment remains undetermined in Japan. Therefore, this retrospective study aimed to ascertain the rate of early surgery among hip fracture patients and investigate its effectiveness, along with "regional clinical pathways" (patient plan of care devised by Japanese clinicians), in reducing the length of hospital stay (LOS) postoperatively. We hypothesized that performing early surgery along with a regional clinical pathway is effective to reduce the postoperative LOS and complications among hip fracture patients. We examined the data of patients diagnosed with femoral neck and peritrochanteric fractures retrieved from the Japanese Diagnosis Procedure Combination database between April 2016 and March 2018. Patients were divided into the early (43,928, 34%; surgery within 2 days of admission) and delayed (84,237, 66%; surgery after 2 days of admission) surgery groups. The difference in postoperative LOS between the two groups was 3 days (early vs. delayed: 29 days vs. 32 days). The early surgery group had more cases of intertrochanteric fractures (57% vs. 43%) and internal fixation (74% vs. 55%) than did the delayed surgery group. In contrast, the delayed surgery group had more cases of femoral neck fractures (43% vs. 57%) and bipolar hip arthroplasty (25% vs. 42%) or total hip arthroplasty (1.2% vs. 3.0%). Moreover, the early surgery group showed a lower incidence of complications, except anemia (12% vs. 8.8%). Logistic regression analysis using the adjusted model revealed that early surgery and implementation of regional clinical pathways reduced LOS by 2.58 and 8.06 days, respectively (p<0.001). Early surgery and implementation of regional clinical pathways for hip fracture patients are effective in reducing postoperative LOS, allowing regional clinical pathways to have a greater impact. These findings will help acute care providers when treating hip fracture patients., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Nishimura et al.

Globally, hip fractures represent a significant and growing public health concern, particularly as the elderly population increases. The timing for surgery following hospitalization for hip fractures is a crucial indicator of acute quality care following recommended surgical guidelines of within two days to minimize complications and mortality. However, factors influencing delayed surgery and its outcomes remain debated. This study, used a national administrative database in South Korea, aimed to examine surgery performed within two days of hospitalization and investigate factors affecting delayed surgical interventions and associated outcomes. Of the hip fracture patients analyzed, 40.6% underwent surgery within two days of hospitalization. Factors associated with delayed surgery included: male patients (OR 1.190; 95% CI 1.022 ~ 1.385), medical aid beneficiary (OR 1.385; 95% CI 1.120 ~ 1.713), higher comorbidity index (OR 1.365; 95% CI 1.163 ~ 1.603, OR 1.612, 95% CI 1.327 ~ 1.958), weekends admission (OR 2.384; 95% CI 2.804 ~ 2.729), admission via outpatient department (OR 1.298, 95% CI 1.071 ~ 1.574). ORIF (OR 0.823, 95% CI 0.691 ~ 0.980) was associated with a significantly low risk of late surgery. While early surgery did not significantly impact in-hospital mortality or complications, it was associated with short and postoperative lengths of stay. This study underscores the need for prompt surgical intervention, particularly in high-risk patient populations, as well as highlights the importance of further research to elucidate the relationship between the timing of surgery and postoperative outcomes., (© 2024.

BACKGROUND The evidence on use of supplementary titanium cable cerclage (TCC) in treating femoral subtrochanteric fractures (FSF) remains scarce. Therefore, this study aimed to investigate the potential therapeutic effects for FSF patients using TCC. MATERIAL AND METHODS A retrospective study of 68 FSF patients treated by a long intramedullary (IM) nailing with (Observation group, n=41) or without (Control group, n=27) TCC was conducted from January 2020 to December 2021. The primary outcome measure was time to postoperative full weight-bearing. Secondary outcome measures were operation time, intraoperative blood loss, number of blood transfusions needed, varus angle loss, excellent and good rate of fracture reduction, Harris score, and survival rate. RESULTS Patients were followed up for 13 to 36 months. The excellent and good rate of fracture reduction was 100% in the Observation group versus 92.6% in the Control group (P=0.013), and the varus angle loss and time to postoperative full weight-bearing in the Observation group were significantly less than in the Control group (P<0.05). The intraoperative blood loss in the Observation group was significantly higher than in the Control group (P<0.001). No differences were noted between groups for Harris scores and survival rates at last follow-up. CONCLUSIONS TCC fixation combined with IM nailing can improve the excellent and good rate of fracture reduction and reduce varus angle loss, as well as shorten the time to full weight-bearing and promote early functional exercise, which offers an effective treatment option for FSF patients who have failed closed reduction.

Purpose: To determine the relationship between three postoperative physiotherapy activities (time to first postoperative walk, activity on the day after surgery, and physiotherapy frequency), and the outcomes of hospital length of stay (LOS) and discharge destination after hip fracture., Methods: A cohort study was conducted on 437 hip fracture surgery patients aged ≥ 50 years across 36 participating hospitals from the Australian and New Zealand Hip Fracture Registry Acute Rehabilitation Sprint Audit during June 2022. Study outcomes included hospital LOS and discharge destination. Generalised linear and logistic regressions were used respectively, adjusted for potential confounders., Results: Of 437 patients, 62% were female, 56% were aged ≥ 85 years, 23% were previously living in a residential aged care facility, 48% usually walked with a gait aid, and 38% were cognitively impaired prior to their injury. The median acute and total LOS were 8 (IQR 5-13) and 20 (IQR 8-38) days. Approximately 71% (n = 179/251) of patients originally living in private residence returned home and 29% (n = 72/251) were discharged to a residential aged care facility. Previously mobile patients had a higher total LOS if they walked day 2-3 (10.3 days; 95% CI 3.2, 17.4) or transferred with a mechanical lifter or did not get out of bed day 1 (7.6 days; 95% CI 0.6, 14.6) compared to those who walked day 1 postoperatively. Previously mobile patients from private residence had a reduced odds of return to private residence if they walked day 2-3 (OR 0.38; 95% CI 0.17, 0.87), day 4 + (OR 0.38; 95% CI 0.15, 0.96), or if they only sat, stood or stepped on the spot day 1 (OR 0.29; 95% CI 0.13, 0.62) when compared to those who walked day 1 postoperatively. Among patients from private residence, each additional physiotherapy session per day was associated with a -2.2 (95% CI -3.3, -1.0) day shorter acute LOS, and an increased log odds of return to private residence (OR 1.76; 95% CI 1.02, 3.02)., Conclusion: Hip fracture patients who walked earlier, were more active day 1 postoperatively, and/or received a higher number of physiotherapy sessions were more likely to return home after a shorter LOS., (© 2024.

Background: The effectiveness of continuous wound infiltration (CWI) as a postoperative pain-control technique has been shown in many surgical procedures. This study investigates the effect of CWI of local anesthetic on postoperative pain control in intertrochanteric fracture patients undergoing hip nailing surgery., Methods: In this randomized clinical trial, 48 patients who were scheduled for hip nailing surgery were randomly assigned to receive ( n  = 24) or not receive ( n  = 24) bupivacaine infusion through a catheter inside the surgical wound, postoperatively. Pain intensity (NRS), required dose of morphine, and drug-related complications within 24 hours of the intervention were assessed and compared., Results: Pain intensity was significantly lower in the bupivacaine group both during the recovery room stay and in the ward in the first 24 hours after the procedure ( P < 0.001). In the recovery room, the control group patients had a higher morphine consumption compared to the bupivacaine group ( P < 0.001) and requested it earlier than the bupivacaine group (60 (45-60) vs. 360 (195-480) minutes) ( P < 0.001). In the ward, all control group patients used the PCA morphine pump, while only 54% of the bupivacaine group self-administered morphine through the pump, with a significantly lower total morphine consumption (1 (0-2) vs. 10 (5-14) mg, P < 0.001). None of the patients in the bupivacaine group required additional morphine, while 37.5% of the control requested additional morphine ( P =0.002). Altogether, the control group had a higher total morphine consumption compared to the bupivacaine group in the first 24 hours (10.5 (6-15.5) vs. 1 (0-2) mg, P < 0.001)., Conclusion: CWI of bupivacaine helps better pain reduction during the early postoperative hours while it reduces opioid consumption, minimizes nausea and vomiting, and improves patient satisfaction., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2024 Arash Farbood et al.)

Background: Tranexamic acid (TXA) is a widely employed intervention in orthopedic surgeries to minimize blood loss and the need for postoperative transfusions. This study focuses on assessing the efficacy and safety of TXA specifically in undernourished older adults undergoing hip fracture procedures., Methods: A total of 216 patients were classified into two groups based on the Geriatric Nutritional Risk Index: undernourished and normal. In total, 82 patients received intravenous TXA at a dosage of 15 mg/kg before incision, with an additional 1 g administered intravenously over a 3-hour period postoperatively. Postoperative hemoglobin (Hb) drop, blood transfusion rate, and the incidence of deep venous thrombosis (DVT) were assessed in each group according to the presence or absence of TXA. Additionally, demographic factors including age, sex, body mass index, and serum albumin were investigated., Results: 51.9% patients were identified as undernourished, experiencing progressive anemia (Hb: 10.9 ± 1.5 g/dL) and hypoalbuminemia (serum albumin: 31.9 ± 8 g/L). In comparison with the normal group, undernourished individuals were more likely to sustain femoral neck fractures (undernutrition vs. normal: 56.2 vs. 42.3%) and less likely to incur trochanteric fractures (undernutrition vs. normal: 43.8 vs. 57.7%) (P = 0.043). TXA administration significantly reduced the transfusion rate (P = 0.014) and Hb drop (P = 0.001) in the normal nutritional group, while its impact on the undernourished group remained less pronounced. There was no significant association between TXA administration and the rate of DVT complications, irrespective of the nutritional status., Conclusions: Undernutrition not only diminishes muscle strength and gait function, leading to various types of hip fractures, but it may also hinder the efficacy of TXA in reducing blood transfusion rates and blood loss., (© 2024.

Introduction: Postoperative delirium in older people may result from the interaction between intrinsic brain vulnerability (e.g. neurodegeneration) and precipitating factors (e.g. surgery induced cytokines). Intrinsic brain vulnerability may be overt (e.g. Alzheimer's disease) or preclinical. In cognitively intact older people presenting for surgery, identification of preclinical neurodegeneration using bedside tools could aid postoperative delirium risk stratification. Thinning of the circumpapillary retinal nerve fibre layer thickness is associated with neurodegenerative disorders e.g. Alzheimer's disease. We propose that thinning of the retinal nerve fibre layer may be present some older people with postoperative delirium due to preclinical neurodegeneration, albeit to a lesser extent than in overt dementia., Objectives: The primary objective: Feasibility of acquiring usable retinal images with the hand-held optical coherence device, at the bedside of older, hip fracture surgery patients. Secondary objective: Comparison of the circumpapillary retinal nerve fibre layer thickness between people who did/did not have postoperative delirium. Proportion of exclusions due to retinal pathology., Method: Feasibility study involving 30, cognitively intact, older people recovering from hip fracture surgery. Retinal images were obtained using the hand-held optical coherence tomography device at the participants' bedside. Imaging was deferred in participants who had postoperative delirium., Results: Retinal images that could be assessed for circumpapillary retinal nerve fibre layer thickness were obtained in 26 participants (22 no postoperative delirium, 4 postoperative delirium). The mean circumpapillary retinal nerve fibre layer thickness was lower in the participants who had postoperative delirium compared to those who did not experience postoperative delirium (Mean (95% CI) of 76.50 (62.60-90.40) vs 89.19 (85.41-92.97) respectively)., Conclusion: Retinal imaging at the patient's bedside, using hand-held OCT is feasible. Our data suggests that the circumpapillary retinal nerve fibre layer may be thinner in older people who experience postoperative delirium compared to those who do not. Further studies are required., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Noah et al.

Introduction: ChatGPT is an artificial intelligence chatbot software programmed for conversational applications using reinforcement learning techniques. With its growing popularity and overall versatility, it is likely that ChatGPT's applications will expand into health care especially because it relates to patients researching their injuries. The purpose of this study was to investigate ChatGPT's ability to accurately answer frequently asked questions regarding hip fractures., Methods: Eleven frequently asked questions regarding hip fractures were posed to ChatGPT, and the responses were recorded in full. Five of these questions were determined to be high-yield based on the likelihood that a patient would ask the question to a chatbot software. The chatbot's responses were analyzed by five fellowship-trained orthopaedic trauma surgeons for their quality and accuracy using an evidence-based approach. The chatbot's answers were rated as "Excellent response requiring no clarification", "Satisfactory response requiring minimal clarification", "Satisfactory response requiring moderate clarification", or "Unsatisfactory response requiring significant clarification.", Results: Of the five high-yield questions posed to the chatbot, no question was determined to be unsatisfactory requiring significant clarification by the authors. The remaining responses were either satisfactory requiring minimal clarification (n = 3) or satisfactory requiring moderate clarification (n = 2)., Discussion: The chatbot was generally found to provide unbiased and evidence-based answers that would be clearly understood by most orthopaedic patients. These findings suggest that ChatGPT has the potential to be an effective patient education tool especially because it continues to grow and improve as a chatbot application., Level of Evidence: Level IV study., (Copyright © 2024 by the American Academy of Orthopaedic Surgeons.)

Background: Hip fracture (HF) in older adults is strongly associated with a greater decline in their activities of daily living (ADLs) and health-related (HRQoL). The present study aimed to evaluate the effects of a family-based care transition program (FBCTP) on ADLs, HRQoL and social support in this age group after HF surgery., Methods: A quasi-experimental design was conducted on 100 older adults who had undergone HFS and were selected by convenience sampling and allocated to the IG (n = 50) and the CG (n = 50). Data were collected utilizing the Barthel Index, the 12-item Short Form Health Survey (SF-12), and the Multidimensional Scale of Perceived Social Support. The FBCTP was delivered in-hospital education sessions, home visit, and a follow-up and telephone counselling session. The data were collected at three stages, including the baseline, four weeks after discharge, and eight weeks later. The level of statistical significance was set at 0.05., Results: The results of the study indicated that the effects of time and group on the increase in ADLs were 15.2 and 36.69 (p < 0.000), respectively, following the completion of the FBCTP. Furthermore, time and group were found to have a positive effect on HRQoL, with an increase of 2.82 and 5.60 units, respectively (p < 0.000). In this context, time and group also interacted in the IG compared to the CG, with scores increasing by 1.86 units over time (p < 0.000). Although the study results indicated that social support improved by 1.98 units over time (p < 0.000), the effects of group alone and the time × group interaction were not statistically significant. This indicates that the program was not effective in accelerating social support., Conclusion: Consequently, nurses, policymakers, and planners engaged in geriatric healthcare may utilize these results to enhance the health status of this age group following HFS., (© 2024.

To investigate the relationship between admission blood urea nitrogen (BUN) levels and postoperative length of stay (LOS) in hip fracture (HF) patients. This retrospective study retrieved related data from the MIMIC-IV database, of which the laboratory variables were taken preoperatively. The patients were divided into 4 groups according to the BUN quartile levels. After exploring the nonlinear relationship between BUN and LOS by generalized additive model, their connection was further analyzed using the generalized linear models, quantile regression models, and interaction analysis. Receiver operating characteristic curve analysis and decision curve analysis were performed to evaluate its value in predicting first intensive care unit admission and in-hospital mortality. Totally 1274 patients with HF were enrolled in the study. There was a nonlinear relationship between BUN and LOS (P < .05). Besides, BUN was an independent predictor for LOS after adjusting different covariates in 3 models (P < .05). Age served as a significant interactor in this relationship (P < .05). Moreover, receiver operating characteristic curve and decision curve analysis revealed the predictive value of BUN for intensive care unit admission and in-hospital mortality in HF. Admission BUN level as a cost-effective and easy-to-collect biomarker is significantly related to LOS in patients with HF. It helps clinicians to identify potential high-risk populations and take effective preventions before surgery to reduce postoperative LOS., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Introduction: The COVID-19 pandemic led to a significant reorganization of health services, potentially affecting the quality of care for major public health concerns such as proximal femoral fractures. This study aimed to investigate potential changes in the timing of various steps in the patient journey after a hip fracture during the pandemic in Piedmont, a region in Northern Italy., Methods: A retrospective study was conducted on the discharge records of patients aged 65 or older who were admitted for hip surgery following a femur fracture in 2019 and 2020. The study examined four-time steps: duration from hospital admission to surgery, length of hospital stay, interval between hospital discharge and admission to the rehabilitation facility, and duration of stay at the rehabilitation facility. To mitigate biases linked to sex and age factors, groups well-balanced across 2019 and 2020 were created using propensity score estimation., Results: The dataset consisted of two cohorts of 583 patients each for the years 2019 and 2020. The average duration from admission to surgery was approximately 1.9 days in both years, with 75% of patients undergoing surgery within 2 days of hospital admission. The average hospital stay reduced from 13.49 days in 2019 to 11.34 days in 2020. The gap between hospital discharge and admission to rehabilitation was approximately 10-12 days, and the average duration of stay at the rehabilitation facility was about 31.6 days., Discussion: The study indicates that healthcare systems can exhibit resilience and adaptability, even during a global pandemic, to ensure high-quality and safe standards of care. However, further long-term studies are needed to fully understand the pandemic's impact on primary health outcomes following hip replacement surgery and subsequent rehabilitation. The potential role of telemedicine in reducing the time between steps also warrants further investigation., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Elhadidy et al.

The aim of our study is to determine if there is an association between phase angle obtained by bioelectrical impedance analysis (BIA) and mortality in older patients with fragility hip fractures. A prospective study of patients over 65 years old and hospitalized with a diagnosis of hip fracture was conducted. BIA was performed 24 to 48 h after surgery. Mortality was recorded, and the optimal phase angle cut-off value for predicting mortality was determined by using receiver operating characteristic (ROC) curves. A total of 262 patients were included. Of the patients studied, 10 (3.8%), 21 (8%), 39 (14.9%) and 53 (20.2%) died at 1, 3, 6 and 12 months after surgery, respectively. The phase angle cut-off for mortality at 12 months was 4.05° in women and 4.65° in men. A total of 94 patients (35.9%) were considered to have a low phase angle. After adjustment for possible confounders, mortality in patients with a low phase angle was 5.1 times higher at 1 month, 3.1 times higher at 3 months, 2.9 times higher at 6 months, and 2.8 times higher at 12 months. Phase angle is associated with prognosis in patients admitted for hip fracture regardless of age and comorbidities and can be positioned as a prognostic tool for mortality at 1, 3, 6 and 12 months.

Hip fractures are common orthopedic injuries that have significant impacts on patients and healthcare systems. Previous studies have shown varying outcomes for hip fracture management in different settings, with diverse postoperative outcomes and complications. While teaching hospital settings have been investigated, no studies have specifically examined hip fracture outcomes in teaching hospitals in Jordan or the broader Middle East region. Therefore, the aim of this study was to investigate this important outcome. A cohort comprising 1268 patients who underwent hip fracture fixation from 2017 to 2020 was analyzed for nine distinct outcomes. These outcomes encompassed time to surgery, ICU admissions, perioperative hemoglobin levels, length of hospital stay, readmission rates, revision procedures, and mortality rates at three time points: in-hospital, at 6-months, and at 1-year post-surgery. The analysis of 1268 patients (616 in teaching hospitals, 652 in non-teaching hospitals) showed shorter mean time to surgery in teaching hospitals (2.2 days vs. 3.6 days, p < 0.01), higher ICU admissions (17% vs. 2.6%, p < 0.01), and more postoperative blood transfusions (40.3% vs. 12.1%, p < 0.01). In-hospital mortality rates were similar between groups (2.4% vs. 2.1%, p = 0.72), as were rates at 6-months (3.1% vs. 3.5%, p = 0.65) and 1-year post-surgery (3.7% vs. 3.7%, p = 0.96). Geriatric hip fracture patients in teaching hospitals have shorter surgery times, more ICU admissions, and higher postoperative blood transfusion rates. However, there are no significant differences in readmission rates, hospital stays, or mortality rates at various intervals., (© 2024. The Author(s).)

Background: "Multidisciplinary fast-track" (MFT) care can accelerate recovery and improve prognosis after surgery, but whether it is effective in older people after hip fracture surgery is unclear., Methods: We retrospectively compared one-year all-cause mortality between hip fracture patients at least 80 years old at our institution who underwent hip fracture surgery between January 2014 and December 2018 and who then received MFT or conventional care. Multivariable regression was used to assess the association between MFT care and mortality after adjustment for confounders., Results: The final analysis included 247 patients who received MFT care and 438 who received conventional orthopedic care. The MFT group showed significantly lower one-year mortality (8.9% vs. 14.4%, P = 0.037). Log-rank testing of Kaplan-Meier survival curves confirmed the survival advantage. However, the two groups did not differ significantly in rates of mortality during hospitalization or at 30 or 90 days after surgery. Regression analysis confirmed that MFT care was associated with lower risk of one-year mortality (hazard ratio [HR] 0.47, 95% confidence interval [CI] 0.281-0.788, P = 0.04), and the survival benefit was confirmed in subgroups of patients with anemia (HR 0.453, 95% CI 0.268-0.767, P = 0.003) and patients with American Society of Anesthesiologists grade III (HR 0.202, 95% CI 0.08-0.51, P = 0.001)., Conclusions: MFT care can reduce one-year mortality among hip fracture patients at least 80 years old. This finding should be verified and extended in multi-center randomized controlled trials., (© 2024. The Author(s).)

Introduction: Hospital systems were strained during the COVID-19 pandemic, and although previous studies have shown that surgical outcomes in healthy hip fracture patients were unaffected in the initial months of the pandemic, subsequent data are limited. This study examined the evolution of hip fracture care throughout the COVID-19 pandemic., Methods: A retrospective review (level III evidence) was done of surgically treated adult hip fractures at a Level 1 academic trauma center from January 2019 to September 2022, stratified into three groups: pre, early, and late pandemic. Continuous variables were evaluated with the Student t-test and one-way analysis of variance, categorical variables were evaluated with chi-squared, P < 0.05 considered significant., Results: Late pandemic patients remained in the hospital 30.1 hours longer than early pandemic patients and 35.7 hours longer than prepandemic patients (P = 0.03). High-energy fractures decreased in the early pandemic, then increased in late pandemic (P < 0.01). Early pandemic patients experienced more myocardial infarctions (P < 0.01). No significant differences in time to surgery, revision surgery, 90-day mortality, or other adverse events were noted., Conclusion: To our knowledge, this is the longest study evaluating hip fracture outcomes throughout the COVID-19 pandemic. These results are indicative of an overburdened regional health system less capable of facilitating patient disposition., (Copyright © 2024 The Authors.

Purpose: This meta-analysis compared the efficacy and safety of Proximal Femoral Nail Antirotation (PFNA) and InterTan Nail in the treatment of intertrochanteric fractures. Given the high incidence of femoral intertrochanteric fractures in the elderly population and its impact on quality of life, choosing the most effective and safest surgical option is crucial. PFNA and InterTan are currently two commonly used techniques, but there is a lack of systematic evaluation comparing their safety and effectiveness. This study aims to fill this knowledge gap through Meta-analysis, providing clinicians with evidence-based treatment recommendations., Materials and Methods: A computer search was used to search for published literature on PFNA and InterTan in the treatment of intertrochanteric fractures in PubMed (Medline), Web of Science, Embase, Cochrane Library (CENTRAL), Cinahl, CBM, and CNKI.A total of 853 related literatures were retrieved, and 15 literatures were finally included. Newcastle-Ottawa-Scale and Cochrane systematic review methodologies were used to assess the quality of the literature. Meta-analysis was performed using Review Manager 5.4 software, following data extraction., Results: The comparison found that during the surgical treatment of intertrochanteric fractures, the operation time, fluoroscopy time, and blood loss in the PFNA group were significantly shorter than those in the InterTan group, and the difference was statistically significant. In terms of postoperative complication rates, the InterTan group had a significant advantage over the PFNA group. Shaft fracture, varus collapse, cut out, screw migration, and pain of hip and thigh were the most likely to occur in the PFNA group, and the differences were all statistically significant. In terms of postoperative efficacy, the results of the PFNA group and the InterTan group were comparable, and there was no significant differences., Conclusions: When selecting surgical techniques for the treatment of femoral intertrochanteric fractures, it is necessary to conduct individualized assessments based on the patient's overall health status, surgical tolerance, and post-operative recovery needs. For patients who cannot tolerate long-term surgery or are in poor physical condition, PFNA may be more appropriate. While for patients who can tolerate long-term surgery or have more complex conditions, InterTan may be more suitable., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Liao et al.

Background: The management of preoperative blood glucose levels in reducing the incidence of postoperative delirium (POD) remains controversial. This study aims to investigate the impact of preoperative persistent hyperglycemia on POD in geriatric patients with hip fractures., Methods: This retrospective cohort study analyzed medical records of patients who underwent hip fracture surgery at a tertiary medical institution between January 2013 and November 2023. Patients were categorized based on preoperative hyperglycemia (hyperglycemia defined as ≥ 6.1mmol/L), clinical classification of hyperglycemia, and percentile thresholds. Multivariate logistic regression and propensity score matching analysis (PSM) were employed to assess the association between different levels of preoperative glucose and POD. Subgroup analysis was conducted to explore potential interactions., Results: A total of 1440 patients were included in this study, with an incidence rate of POD at 19.1% (275/1440). Utilizing multiple logistic analysis, we found that patients with hyperglycemia had a 1.65-fold increased risk of experiencing POD compared to those with normal preoperative glucose levels (95% CI: 1.17-2.32). Moreover, a significant upward trend was discerned in both the strength of association and the predicted probability of POD with higher preoperative glucose levels. PSM did not alter this trend, even after meticulous adjustments for potential confounding factors. Additionally, when treating preoperative glucose levels as a continuous variable, we observed a 6% increase in the risk of POD (95% CI: 1-12%) with each 1mmol/L elevation in preoperative glucose levels., Conclusions: There exists a clear linear dose-response relationship between preoperative blood glucose levels and the risk of POD. Higher preoperative hyperglycemia was associated with a greater risk of POD., Clinical Trial Number: NCT06473324., (© 2024. The Author(s).)

Objective: We aimed to investigate the effects of anesthesia methods and perioperative procedures on mortality in geriatric patients operated for hip fracture., Patients and Methods: This retrospective study included patients over 65 years of age who underwent hip fracture surgery. Demographic data, risk scores, perioperative and anesthesia management were analyzed in terms of mortality., Results: Data from 451 patients who were eligible for the study were analyzed. It was determined that there was no difference in mortality between the anesthesia methods administered to the patients in hip fracture surgery (p>0.05).  Being male increased the mortality risk by 4.568 times (95% CI: 1.215-17.168), and a one-unit increase in the number of erythrocyte suspensions given perioperatively increased the mortality risk by 2.801 times (95% CI: 1.509-5.197). Additionally, an American Society of Anesthesiologists (ASA) II score increased the mortality risk by 0.120 times (95% CI: 0.021-0.690), and a higher modified Charlson comorbidity index (mCCI) of 5-7 increased the mortality risk by 0.052 times (95% CI: 0.009-0.289)., Conclusions: Although high ASA and mCCI scores, male sex, and blood transfusion were associated with mortality in geriatric hip fracture surgery, we found that the method of anesthesia did not affect mortality.

Purpose: The optimal choice of distal locking modes remains a subject due to limited available data, and therefore, this study aims to investigate the relationship between distal locking mode and postoperative mechanical complications in an intertrochanteric fracture (ITF) population who underwent closed reduction and intramedullary fixation with a PFNA-II., Methods: Patients aged 65 years or older who underwent surgery with PFNA-II fixation in a university teaching hospital between January 2020 and December 2021 were potentially eligible. Based on the distal locking mode, patients were classified into static, dynamic, and limited dynamic groups, among which the differences were tested using univariate analysis. Multivariate logistic regression was used to examine whether the distal locking mode was independently associated with the risk of postoperative one year mechanical complications, adjusting for covariates and potential confounders. Subgroup analyses were performed to evaluate the robustness of the findings., Result: Among 507 eligible patients, 33 (6.5%) developed postoperative mechanical complications. In the univariate analysis, sex (P = 0.007), fracture type (P = 0.020), LAT Parker ratio (P = 0.023), and lateral femoral (P = 0.003) wall showed that the differences were significant. Compared to the static group, the limited dynamic group and the dynamic group showed higher odds of postoperative mechanical complications (OR = 3.314, 95% CI: 1.215-9.041; and OR = 3.652, 95% CI: 1.451-9.191, respectively). These associations were robust across a series of analyses, including adjusting for confounders and subgroup analyses., Conclusion: Using a distal non-static locking mode significantly increases the risk of postoperative mechanical complications, and static locking could be a preferable option when treating an intertrochanteric fracture., (© 2024.

Introduction: There are no clear recommendations for the perioperative timing and initiation of venous thromboembolism pharmacologic prophylaxis (VTEp) among polytrauma patients undergoing high-risk bleeding orthopedic operative intervention, leading to variations in VTEp administration. Our study examined the association between the timing of VTEp and VTE complications in polytrauma patients undergoing high-risk operative orthopedic interventions nationwide., Methods: We performed a retrospective cohort study of trauma patients 18 years or older who underwent high-risk bleeding operative orthopedic interventions for pelvic, hip, and femur fractures within 24 hours of admission at American College of Surgeons-verified trauma centers using the 2019-2020 American College of Surgeons Trauma Quality Improvement Program databank. We excluded patients with a competing risk of nonorthopedic surgical bleeding. We assessed operative orthopedic polytrauma patients who received VTEp within 12 hours of orthopedic surgical intervention compared with VTEp received beyond 12 hours of intervention. The primary outcome assessed was overall VTE events. Secondary outcomes were orthopedic reinterventions within 72 hours after primary orthopedic surgery, deep venous thromboembolism, and pulmonary embolism rates., Results: The study included 2,229 patients who underwent high-risk orthopedic operative intervention. The median time to VTEp initiation was 30 hours (interquartile range, 18-44 hours). After adjustment for baseline patient, injury, and hospital characteristics, VTEp initiated more than 12 hours from primary orthopedic surgery was associated with increased odds of VTE (adjusted odds ratio, 2.02; 95% confidence interval, 1.08-3.77). Earlier initiation of prophylaxis was not associated with an increased risk for surgical reintervention (hazard ratio, 0.90; 95% confidence interval, 0.62-1.34)., Conclusion: Administering VTEp within 24 hours of admission and within 12 hours of major orthopedic surgery involving the femur, pelvis, or hip demonstrated an associated decreased risk of in-hospital VTE without an accompanying elevated risk of bleeding-related orthopedic reintervention. Clinicians should reconsider delays in initiating or withholding perioperative VTEp for stable polytrauma patients needing major orthopedic intervention., Level of Evidence: Therapeutic/Care Management; Level III., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: Biomechanical superiority of intramedullary nails over extramedullary implants has been proved for subtrochanteric fractures. Nevertheless, postoperative management of these patients has not changed, with high rates of protected weight-bearing after intramedullary nailing. The purpose of this study is to determine the mechanical complications of immediate postoperative full weigh-bearing for subtrochanteric femur fractures in elderly patients treated with a cephalomedullary nail., Methods: We performed a retrospective case series study from patients treated with a cephalomedullary nail for subtrochanteric fractures (AO/OTA 31A.3 and 32A-32C) over a nine-year period. Patients in the immediate full weight-bearing (IFWB) group received orders for immediate full weight bear as tolerated on postoperative 48 h. Patients in the non- or limited- weight-bearing (NLWB) group received orders not to full weight bear in the immediate postoperative., Results: There were five (2.7%) cases of implant failure including four cutouts and one nail breakage that needed a reoperation. Of them, one (2.2%) followed the NLWB protocol and four (2.9%) followed the IFWB protocol. Mean length of stay was 7.9 days (median 8, range 3-21) in the NLWB group and 10.7 days (median 8, range 2-60) in the IWBAT group. The NLWB group observed a 2.8-day shorter postoperative length of stay when compared to the IFWB, but the median remained equal., Conclusion: This study suggests that geriatric patients with subtrochanteric fractures treated by intramedullary nailing and in which a good fracture reduction was achieved, may be able to tolerate immediate postoperative full weight-bearing, not increasing reoperation rates due to implant failure., (© 2024.

Introduction: Intensive care unit risk stratification models have been utilized in elective joint arthroplasty; however, hip fracture patients are fundamentally different in their clinical course. Having a critical care risk calculator utilizing pre-operative risk factors can improve resourcing for hip fracture patients in the peri‑operative period., Methods: A cohort of geriatric hip fracture patients at a single institution were reviewed over a three-year period. Non-operative patients, peri‑implant fractures, additional procedures performed under the same anesthesia period, and patients admitted to the intensive care unit (ICU) prior to surgery were excluded. Pre-operative laboratory values, Revised Cardiac Risk Index (RCRI), and American Society of Anesthesiologists (ASA) scores were calculated. Pre-operative ambulatory status was determined. The primary outcome measure was ICU admission in the post-operative period. Outcomes were assessed with Fisher's exact test, Kruskal-Wallis test, logistic regression, and ROC curve., Results: 315 patient charts were analyzed with 262 patients meeting inclusion criteria. Age ≥ 80 years, ASA ≥ 4, pre-operative hemoglobin < 10 g/dL, and a history of CVA/TIA were found to be significant factors and utilized within a "training" data set to create a 4-point scoring system after reverse stepwise elimination. The 4-point scoring system was then assessed within a separate "validation" data set to yield an ROC area under the curve (AUC) of 0.747. Score ≥ 3 was associated with 96.8 % specificity and 14.2 % sensitivity for predicting post-op ICU admission. Score ≥ 3 was associated with a 50 % positive predictive value and 83 % negative predictive value., Conclusion: A hip fracture risk stratification scoring system utilizing pre-operative patient specific values to stratify geriatric hip patients to the ICU post-operatively can improve the pre-operative decision-making of surgical and critical care teams. This has important implications for triaging vital hospital resources., Level of Evidence: III (retrospective study)., Competing Interests: Declaration of competing interest SM receives royalties from Smith+Nephew Inc., Depuy Synthes, and serves as a consultant for Stryker Corporation.

Objective: To understand immediate and long-term outcomes following hip fracture surgery in adults with schizophrenia., Methods: Retrospective population-based cohort study leveraging health administrative databases from Ontario, Canada. Individuals aged 40-105 years with hip fracture surgery between April 1, 2009 and March 31, 2019 were included. Schizophrenia was ascertained using a validated algorithm. Outcomes were: 30-day mortality; 30-day readmission; 1-year survival; and subsequent hip fracture within 2 years. Analyses incorporated Generalized Estimating Equation models, Kaplan-Meier curves, and Fine-Gray competing risk models., Results: In this cohort study of 98,126 surgically managed hip fracture patients, the median [IQR] age was 83[75-89] years, 69.2% were women, and 3700(3.8%) had schizophrenia. In Fine-Gray models, schizophrenia was associated with subsequent hip fracture ( sd RH, 1.29; 95% CI, 1.09-1.53), with male patients with schizophrenia sustaining a refracture 50 days earlier. In age- and sex-adjusted GEE models, schizophrenia was associated with 30-day mortality (OR, 1.31; 95% CI, 1.12-1.54) and readmissions (OR, 1.40; 95% CI, 1.25-1.56). Kaplan-Meier survival curves suggested that patients with schizophrenia were less likely to be alive at 1-year., Conclusions: Study highlights the susceptibility of hip fracture patients with schizophrenia to worse outcomes, including refracture, with implications for understanding modifiable processes of care to optimize their recovery., Competing Interests: Declaration of competing interest Hina Ansari has received consultancy fees from Brookfield Chair in Fracture Prevention outside of submitted work.

Introduction: The use of hypnotic drugs is common in the elderly and is associated with negative health outcomes. Our aim was to evaluate the prevalence of hypnotic drug usage amongst hip fracture patients undergoing a rehabilitation program and investigate any potential associations between hypnotic drug use and rehabilitation outcomes in a post-acute care setting., Methods: A retrospective analysis of 440 geriatric hip fracture patients was conducted from 1/1/2019 to 12/2021 in a geriatric rehabilitation center. The main outcome measures were the Functional Independence Measure (FIM), the motor FIM effectiveness and length of stay (LOS)., Results: Two hundred and twenty-eight (51.7 %) patients out of the entire cohort (440)), were prescribed hypnotic drugs. These patients exhibited a significantly lower rate of diabetes (p = 0.025), a higher rate of depression (p = 0.003), and lower albumin levels (p = 0.023) upon admission to rehabilitation in comparison to untreated patients. No significant differences were observed between the two patient groups in functional rehabilitation outcomes or LOS. Moreover, no correlation was established between the hypnotic drug burden during rehabilitation and the outcome measures. Furthermore, no significant differences were found between patients treated with hypnotic drugs on admission and those who were prescribed these drugs during rehabilitation. The type of hypnotic drug did not affect these results., Conclusion: The use of hypnotic drugs by elderly individuals undergoing a rehabilitation program after a hip fracture is unlikely to have an adverse impact on their short-term rehabilitation outcomes. Consequently, there may not be an immediate necessity to discontinue these drugs upon admission. Nevertheless, the use of hypnotic drugs should be approached with caution and minimized whenever possible due to an increased fall risk and other adverse effects., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

Purpose: According to Vancouver classification, B2 type fractures are most often treated with removal of the loose stem and implantation of a long stem that bypasses the fracture site. However, there is a controversy about the stem fixation that should be used: cemented or cementless. Hence, this study aims to compare cemented and cementless stems in prosthetic revision due to Vancouver B2 (VB2) periprosthetic hip fracture., Methods: A retrospective study was done including all the patients treated with stem exchange due to VB2 periprosthetic hip fracture in a tertiary hospital between 2015 and 2022. Patients were divided into two groups according to the stem fixation used: cemented or cementless. Functional outcomes, hospital stay, surgical time, complication rate, and mortality were compared between the two groups of patients., Results: Of the 30 included patients, 13 (43.4%) were treated with cementless stems and 17 (56.7%) with cemented stems. There were no statistically significant differences in age, gender, anesthesia risk scale (ASA) or functional capacity prior to the intervention. Patients treated with cementless stems had a higher complication and reintervention rate than those treated with cemented stems: 62 and 45% versus 34 and 6% (p = 0.035; p = 0.010), respectively. Furthermore, in the group of cementless stems a higher proportion of non-union was found (53.8% vs. 17.6%; p = 0.037). Also, the hospital stay (33 vs. 24 days; p = 0.037) and the time to full weight-bearing (21 days vs. 9 days; p < 0.001) were longer in the cementless stem group., Conclusion: Cemented fixation in stem revision due to Vancouver B2 periprosthetic hip fracture could be an optimal option with faster recovery which could decrease the rate of complications and reintervention, without compromising the fracture healing and patient mortality. Thus, this option can be considered when an anatomical reduction can be obtained, especially in elderly patients with multiple comorbidities in which a less aggressive surgical option should be considered., (© 2024.

We determined the prognostic value of nutritional status for outcome after hip fracture. Nutritional status was a strong independent prognostic factor for clinical outcome and 5-year mortality. Physical function showed incomplete recovery. Elderly care should focus on prevention already before hip fracture., Purpose: To determine the prognostic value of nutritional status in hip fracture patients for multiple clinical and functional outcomes over 6 months, and for new fractures and survival over 5 years post-fracture., Methods: We included 152 well-characterized subjects (age 55+ years) with a hip fracture from a previously published randomized controlled trial. Nutritional status was appraised using the Mini Nutritional Assessment (MNA). Multivariable linear, logistic and Cox regression models were fitted, adjusted for age, sex, ASA score, group and additional prognostic covariates identified in backward regression models., Results: At baseline, impaired nutritional status was significantly associated with physical disability, depression, impaired cognition and lower quality of life. Prospective analyses showed that impaired baseline nutritional status was an independent prognostic factor for postoperative complications (OR 2.00, 95%CI 1.01-3.98, p = 0.047), discharge location from hospital (home vs. rehabilitation clinic, OR 0.41, 95%CI 0.18-0.98, p = 0.044), hospital readmission (OR 4.59, 95%CI 1.70-12.4, p = 0.003) and total length of hospital stay (HR of being discharged: 0.63, 96%CI 0.44-0.89, p = 0.008), as well as for 5-year mortality (HR 3.94, 95%CI 1.53-10.2, p = 0.005), but not for risk of new fractures (5y-HR 0.87, 95%CI 0.34-2.24, p = 0.769). Curves of physical disability over time showed that the three nutritional status categories followed almost parallel trajectories from baseline until 6 months after hip fracture, without complete recovery and even with further deterioration in malnourished subjects from 3 to 6 months post-fracture., Conclusion: As baselline nutritional status is a strong independent prognostic factor for clinical outcome after hip fracture, affecting even five-year survival, elderly health care should focus on prevention and identification of at-risk individuals already before hip fracture., (© 2024.

Background: Hip fracture surgeries in elderly patients often require spinal or general anesthesia, posing risks of severe hypotension and inadequate pain management. The optimal anesthesia type for minimizing these risks remains undetermined. Preliminary studies suggest that a combination of fascia iliaca block (FIB) and low-dose low-specific-gravity spinal anesthesia (LLSA) might offer a solution, but comprehensive evidence is lacking., Objectives: This study aimed to assess the efficacy of combining FIB with LLSA for reducing severe hypotension and enhancing analgesia during hip fracture surgery in elderly patients., Study Design: A prospective, randomized controlled trial was conducted., Setting: An operating theatre of a tertiary hospital., Methods: The study comprised 68 patients. They were separated into 2 equal parallel groups 34 patients each: the FIB+LLSA group and the general anesthesia (GA) group. Patients aged 75-96 undergoing primary hip arthroplasty for hip fracture were randomized to receive either FIB+LLSA or GA. The primary outcome was the incidence of severe hypotension; secondary outcomes included postoperative pain, use of rescue analgesia, vasopressor dosage, and complications., Results: We found a significantly lower incidence of severe hypotension in the FIB+LLSA group compared to the GA group (32.4% vs 67.6%). Additionally, postoperative pain scores were significantly lower, and the need for rescue analgesia was reduced in the FIB+LLSA group. Vasopressor use during surgery was also significantly lower in the FIB+LLSA group. The hospital stay was shorter in the FIB+LLSA group, with an average of 5.9 days compared to 6.7 days in the GA group., Limitations: The study's limitations include its single-center nature, which may limit the generalizability of the findings. Additionally, the inability to conduct a double-blind study could introduce biases, though measures were taken to minimize this. The sample size might not be sufficient to determine the broader implications of LLSA., Conclusions: Combining FIB with LLSA for elderly patients undergoing hip fracture surgery significantly reduces the incidence of severe intraoperative hypotension and postoperative pain. It also decreases the need for rescue analgesia and shortens hospital stays, suggesting that FIB+LLSA could be a beneficial regional anesthesia technique for elderly hip fracture surgery patients, aligning with enhanced recovery protocols.

Objective: AO/OTA 31-A3.3 intertrochanteric fracture is the most unstable type of intertrochanteric fracture, with a high rate of postoperative complications and implant failure. We have designed a new intramedullary fixation, proximal femoral totally bionic nail (PFTBN), for the treatment of A3.3 intertrochanteric fracture. To test its biomechanical performance, we adopted the method of finite element analysis and compared PFTBN with proximal femoral nail antirotation (PFNA) and proximal femoral bionic nail (PFBN, another internal fixation we previously designed for stable intertrochanteric fractures)., Methods: Mimics, 3-matic, ANSYS, and other software were used to construct a highly precise and realistic 3D digital model of the human femur. An AO/OTA 31-A3.3 intertrochanteric fracture of the femur was constructed according to the 2018 classification of AO/OTA, and then assembled with PFNA, PFBN and PFTBN models, respectively. The stress distribution and displacement distribution of the three groups of constructs were tested under three times the body weight load and one-foot standing configuration., Results: In terms of maximum stress and maximum displacement, the PFTBN group outperforms the PFBN group, and the PFBN group, in turn, surpasses the PFNA group. The maximum stress of PFTBN group was 408.5 Mpa, that of PFBN group was 525.4 MPa, and that of PFNA group was 764.3 Mpa. Comparatively, the maximum stress in the PFTBN group was reduced by 46.6% when contrasted with the PFNA group. Moreover, the stress dispersion within the PFTBN group was more evenly distributed than PFNA group. Regarding maximum displacement, the PFTBN group displayed the least displacement at 5.15 mm, followed by the PFBN group at 7.32 mm, and the PFNA group at 7.73 mm. Notably, the maximum displacement of the PFTBN group was 33.4% less than that observed in the PFNA group. Additionally, the relative displacement between the fragment and implant at the tip of pressure screw or helical blade was 0.22 mm in the PFTBN group, 0.34 mm in the PFBN group, and substantially higher 0.51 mm in the PFNA group., Conclusion: The "lever-reconstruction-balance" theory provides a new perspective for us to understand the mechanical conduction of the proximal femur. Compared with PFNA, in treating A3.3 intertrochanteric fractures PFTBN can better reconstruct the function of lateral wall, restore physiological mechanical conduction, increase postoperative stability, and finally reduce the risk of postoperative cut-out and implant failure. It might be a better alternative for the treatment of A3.3 intertrochanteric fracture., (© 2024 The Authors. Orthopaedic Surgery published by Tianjin Hospital and John Wiley & Sons Australia, Ltd.)

The management of the older person with a displaced intracapsular hip fracture is one of the most significant aspects of musculoskeletal trauma. These patients require prompt, integrated pathway delivered care. The care delivered outside of the operating theatre and that performed within, are intertwined. Traditionally, surgeons have focussed predominantly only on the operative elements. In modern trauma care for older people, this focus must broaden. We provide for the first time a comprehensive overview of all elements of care for this important patient group. This brings together pathway elements from the National Hip Fracture Database Key Performance Indicators and NICE guidance alongside a synthesis of all current research output for intracapsular hip fracture., Competing Interests: Declaration of competing interest Neither Will Eardley no Antony Johansen have any conflict of interest with regards this submission.

Introduction: Periprosthetic femoral fractures (PPFFs) represent an important healthcare problem, with a rising incidence noted due to an increase in the number of arthroplasty surgeries being performed. There is a current lack of national consensus as to how these complex, often frail patients are managed., Aims: Our primary aim was to present the epidemiology of PPFFs in England and Wales over the first two years of data collection by the National Hip Fracture Database (NHFD). Secondary aims included how well the NHFD Key Performance Indicators (KPIs) are met for PPFF patients, whether centres reporting a higher burden of PPFF patients are more likely to meet KPIs compared to lower volume centres, and to also identify if regional variation in care for these patients exist., Methods: Patients aged 60 years or over, admitted to any acute hospital in England or Wales with a PPFF within the period 1st January 2020 to 31st December 2021 were included. Fractures were classified using the Vancouver system. The primary outcome of interest was the incidence of PPFF in England and Wales. Secondary outcomes included i) geographical distribution, ii) pattern of injury, iii) treatment received, iv) KPI performance nationally, v) KPI performance by top 5 highest volume hospitals vs the rest, vi) KPI performance by region and vii) KPI performance compared with native hip fracture patients., Results: A total of 5,566 PPFFs were reported during our study period. A 31 % increase in cases was seen between 2020 and 2021 (2,405 to 3,161). The South-West of England reported the highest burden of PPFFs (14 % of all cases reported in 2021). Vancouver B subtypes were most common around hip replacements (62 %) and C subtype around knee replacements (55 %). A total of 4,598 patients (82.6 %) underwent operative management. There was regional variation in KPI attainment. When compared to KPI attainment for native hip fractures PPFF care under performed in most regions and domains. High volume PPFF centres were not associated with improved attainment of KPIs., Conclusion: We have described the incidence, nature, and management of PPFF at national and regional levels using routinely collected NHFD data. Both numerically and due to case complexity, PPFF are a considerable challenge to patients and health services alike. This epidemiology is not captured by other existing datasets and increased case contribution to the NHFD is encouraged to improve understanding and enable prioritisation and delivery of further care and research., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare, (Copyright © 2024.

Aim: This cohort study aimed to explore the connection between postoperative hyperactive delirium and major complications in elderly patients undergoing emergency hip fracture surgery., Methods: Elderly patients aged 65 years and older undergoing emergency hip fracture surgery were included in the study. The presence of postoperative hyperactive delirium was assessed, and logistic regression analysis, following propensity score matching, was conducted to investigate the association between postoperative hyperactive delirium and major complications occurring 30 and 90 days post-surgery. The analysis controlled for potential confounding factors., Results: After propensity score matching, the analysis included 13 590 patients, equally distributed with 6795 in each group. The group experiencing postoperative hyperactive delirium exhibited a significantly elevated risk of 30-day postoperative complications, including acute renal failure, pneumonia, septicemia, and stroke, with adjusted odds ratios ranging from 1.64 to 2.39. Furthermore, this group displayed notably higher rates of 90-day postoperative complications, encompassing mortality, acute renal failure, pneumonia, septicemia, and stroke, with a significantly increased incidence of mortality within 90 days., Conclusion: Postoperative hyperactive delirium in elderly patients undergoing emergency hip fracture surgery is significantly linked to an increased risk of major complications at both 30 and 90 days post-surgery. These findings underscore the critical importance of delirium prevention and management in this patient population, offering the potential to reduce the occurrence of postoperative complications.

Background: AO/OTA 31A3 fractures (A3 fractures) have risk for postoperative complications with major impact on morbidity and mortality. For older patients, limited information is available for factors associated with postoperative complications. We aimed to assess factors associated with postoperative complications after surgery using cephalomedullary nails., Methods: A retrospective cohort study was conducted using the information on patients aged ≥65 years who underwent surgery using cephalomedullary nails for trochanteric fractures due to low-energy trauma in three hospitals. Postoperative complications were diagnosed when patients were identified as nonunion, cutout of lag screw, or nail breakage. First, we compared differences including age, sex, body mass index, American Society of Anesthesiologists physical status classification system, preoperative waking ability, fracture type, nail length, neck shaft angle, reduction method, reduction quality and tip apex distance between patients with and without postoperative complications. Second, multivariable logistic regression analysis was employed to assess factors associated with postoperative complications resulting from A3 fractures., Results: Among 120 patients with A3 fractures, postoperative complications were identified in 12 patients (10.0%). Postoperative complications were significantly more likely to develop among patients with poor reduction quality (adjusted odds ratio [95% confidence interval], 35.0 [4.43-275.9]) and a tip-apex distance ≥25 mm (16.4 [1.92-140.3])., Conclusions: These findings suggest that surgeons should aim to perform appropriate postoperative reduction and to prevent postoperative complications when using a cephalomedullary nail for A3 fractures among older patients., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2023.
