Total hip arthroplasty (THA) aims to restore joint function and relieve pain. New technology, such as robot assistance, offers the potential to reduce human error, improve precision, and improve postoperative outcomes. The aim of this study was to compare outcomes between conventional and robot-assisted THA. This is a retrospective cohort study utilizing a national database from 2016 to 2019. Patients undergoing THA, conventional or robot-assisted, were identified via the International Classification of Diseases, Tenth Revision code. Multivariate regressions were performed to assess outcomes between groups. Negative binomial regressions were performed to assess discharge disposition, readmission, and reoperation. Gamma regressions with log-link were used to assess total charges and lengths of hospital stays. Patient demographics and comorbidities, measured via the Elixhauser comorbidity index, were controlled for in our analyses. A total of 1,216,395 patients undergoing THA, 18,417 (1.51%) with robotic assistance, were identified. Patients undergoing robot-assisted procedures had increased surgical complications (odds ratio [OR] 1.31 [95% confidence interval [CI] 1.14 to 1.53]; P <.001), including periprosthetic fracture (OR 1.63 [95% CI 1.35 to 1.98]; P <.001). Notably, these patients also had significantly greater total charges (OR 1.20 [95% CI 1.11 to 1.30]; P <.001). Robotic assistance in THA is associated with an increased risk of surgical complications, including periprosthetic fracture, while incurring greater charges. Level III; Retrospective Cohort Study.

Introduction: To improve outcomes after knee or hip surgery, better insight is needed in long-term recovery patterns in the context of ageing-related decline. We examined long-term trajectories of physical functioning (PF) in older women with and without hip and knee surgery and described profiles of cases with higher and lower resilience after surgery. Methods: This observational study used data from 10,434 women (73–79 years) who completed survey 2 of the Australian Longitudinal Study on Women's Health. Data were used from surveys 2 (1999) to 6 (2011). Covariable-adjusted linear mixed models were run to examine the surgery-by-time (−12 to +12 years) interaction in association with PF (SF-36 subscale). The differences between observed and expected PF were calculated, with positive/negative values reflecting higher/lower resilience, respectively. Results: Women with hip surgery (n = 982) had lower PF than those without surgery (n = 8,117) (p < 0.001). Among hip surgery patients, the decline was more rapid pre-surgery than post-surgery (Δslope = −0.7, p < 0.001). Women with knee surgery (n = 1,144) had lower PF than those without surgery (n = 7,971), but with a slower rate of decline (p = 0.01). Among knee surgery patients, the rate of decline was similar pre- and post-surgery (Δslope = −0.3, p = 0.25). Both in hip and knee patients, women with higher resilience had fewer comorbidities and symptoms and were more often physically active and independent in daily activities than those with lower resilience (all p < 0.05). Conclusion: Compared with women without surgery, PF was lower and declined more rapidly around the time of hip surgery, but not for knee surgery. Women with better long-term recovery after surgery had fewer health problems and were more independent around the time of surgery. [ABSTRACT FROM AUTHOR]

Purpose: Bone marrow stimulation is a common treatment for full‐thickness cartilage defects in the hip joint. However, common procedures may result in poor fibrous repair tissue and changes to the subchondral anatomy. This study investigated the clinical outcome of a cohort of International Cartilage Repair Society (ICRS) grades 3 and 4 cartilage defects treated with bone marrow stimulation compared to those who received simple debridement/chondroplasty. Methods: In this retrospective registry study, 236 patients with uni‐focal acetabular chondral lesions of the hip up to 400 mm² (mean 177.4 ± 113.4 mm²) and of ICRS grade ≥3 with follow‐up of at least 12 months (mean 33.2 ± 15.3 months) were included. Eighty‐one patients underwent bone marrow stimulation (microfracture: n = 44, abrasion: n = 37) besides treatment of the underlying pathology, 155 patients underwent defect debridement/chondroplasty. The patient‐reported outcome was measured using the International Hip Outcome Tool 33 (iHOT33) score and the Visual Analogue Scale (VAS) for pain. Results: iHOT33 and VAS both improved highly statistically significantly (p < 0.001) in the debridement group after 6, 12, 24, 36 and 60 months compared to the preoperative scores, whereas iHOT33 and VAS after microfracture or abrasion did not show statistically significant changes over time. Twenty‐four and sixty months postsurgery the debridement group revealed significant higher scores in the iHOT33 compared to the bone marrow stimulation groups. Conclusion: Patients with chondral lesions of the hip ≤400 mm2 sustainably benefit from arthroscopic debridement under preservation of the subchondral bone plate in terms of functional outcome and pain in contrast to patients treated with bone marrow stimulation. These findings discourage the currently recommended use of microfracture in the hip joint. Level of Evidence: Level III. [ABSTRACT FROM AUTHOR]

Purpose: (1) To determine the prevalence, magnitude and distribution pattern of acetabular rim ossification in patients with femoroacetabular impingement syndrome (FAIS) and (2) to determine the association between acetabular rim ossification and rotational abnormalities of the hip. Methods: Patients underwent hip arthroscopic surgery for FAIS at our institute between January 2021 and May 2022 were retrospectively reviewed. Patients were included if preoperative computed tomography (CT) images of the operated hip and ipsilateral distal femur were available for the measurement of femoral and acetabular anteversion. The presence and size of acetabular rim ossification were evaluated on coronal CT sections for the superior half of the acetabulum on each clockface location. The associations between acetabular rim ossification and radiographic parameters of hip rotational morphology were examined. Results: A total of 214 hips were included. Acetabular rim ossification was found in 167 hips (78%) and the most common locations were 10 and 11 o'clock. Patients presenting with acetabular rim ossification had a mean size of 4.6 ± 1.6 mm. It was the largest at 9 o'clock position (4.9 ± 2.2 mm), with a decreasing trend in size from posterior to anterior. Logistics regression analysis found age was associated with the occurrence of posterior ossification (p = 0.002). Linear regression analysis found age (p = 0.049) and male sex (p < 0.001) were significantly correlated with the size of ossification. Patients with increased cranial combined anteversion had larger posterior ossification than patients with normal and decreased cranial combined anteversion (4.2 ± 2.9 vs. 3.1 ± 2.5 mm, p = 0.016; 4.2 ± 2.9 vs. 2.5 ± 2.4 mm, p = 0.005). Conclusion: Increased combined anteversion is associated with greater posterior acetabular rim ossification. The presence and size of acetabular rim ossification are positively associated with older age and male sex. Level of Evidence: Level III. [ABSTRACT FROM AUTHOR]

Purpose: Robot-assisted total hip arthroplasty (RA-THA) helps with precise orientation of the prosthesis, but some RA-THA procedures are aborted intraoperatively and are converted to manual total hip arthroplasty (THA). This study aimed to analyse why RA-THA is sometimes aborted intraoperatively and to make recommendations accordingly. Methods: A total of 429 consecutive Mako THA cases in our prospective database from August 2018 to June 2021 were included in our study. All robotic procedures aborted intraoperatively for any reason were recorded. The patients' demographics, diagnoses, and surgeons' information were included in the statistical analysis to pinpoint the risk factors for intraoperative robot to manual conversion. Results: Intraoperative RA-THA abortions occurred in 17 cases (3.96%) and the patients had to be converted to manual THA. The adverse events leading to intraoperative abortions included pelvic array loosening or malposition (5, 1.17%), inaccurate bone mapping or construction (6, 1.40%), inaccurate initial registration (4, 0.93%), and other reasons (2, 0.47%). Conclusion: Robot-related adverse events could be found in all perioperative steps of RA-THA, and some of these events might result in intraoperative abortion. Complex hip disease was a statistically significant factor for an increased risk of intraoperative abortion of RA-THA. Standardized surgical procedures and preoperative assessments can be helpful in reducing the rate of RA-THA abortions. [ABSTRACT FROM AUTHOR]

Purpose: We aim to analyse and compare the efficacy of the excision of HO around the hip with and without CT-guided navigation. We also aim to compare the functional outcome between CT navigation guided versus conventional excision of HO. Patients and methods: This study is a retrospective analysis of prospectively collected data from 2015 to 2022. There were 23 patients (24 hips) in the final cohort. Intraoperative CT navigation guided excision was performed in 7 hips and conventional excision of HO was done in 17 hips. The HO was classified by Brooker's grading in radiographs. CT scan was taken preoperatively in all patients to exactly identify the volume, location and preoperative planning. The functional outcome was analysed according to Harris Hip Score (HHS) and International Hip Outcome Tool (iHOT) for self-ambulatory patients and improvement in the sitting or nursing care was assessed in patients mobilising with wheelchair or walker support. Any complications or recurrence noted postoperatively and in follow-up were recorded. Results: The mean follow-up was 41.2 months in the CT navigation-guided excision group and 55 months in the conventional excision group. According to Brooker's grading, grade IV was present in 20 hips and grade III in four hips. Twelve patients were self-ambulatory and the other 12 patients were requiring support for mobilisation. There was a significant improvement in the HHS from 21.3 ± 3.7, 18.3 ± 2.5 preoperatively to 75.2 ± 8.3, 72.2 ± 4.3 postoperatively in the CT navigation guided and conventional group respectively (p < 0.001) in the self-ambulatory group. There was one anterior wall and one partial posterior wall fracture in the conventional group. One patient in the conventional group had a deep infection and recurrence. One patient had a superficial infection and another had superficial vein thrombosis in the CT guided excision group. Conclusion: Intraoperative CT navigation helps to exactly localize the HO and facilitates safe excision. Functional excision of the HO leads to better nursing care and functional outcomes between both groups. [ABSTRACT FROM AUTHOR]

Purpose: The acetabular coverage in osteonecrosis of the femoral head (ONFH) affects the need for surgical intervention, and the collapse of the femoral head remains unclear. This study aimed to evaluate the relation between the acetabular coverage and the need for surgical treatment and femoral head collapse. Methods: The study included 158 patients with 252 hips with glucocorticoid administration and idiopathic ONHF without osteoarthritis changes. The mean age at the first visit was 45.2 years, and the mean follow-up period was 92.2 months. All ONFH hips were subsequently divided into two groups: those needing surgical intervention and those without surgery. Additionally, it divided 167 initially non-collapsed hips into those that either later collapsed or not. Radiographic parameters with the centre-edge angle, acetabular roof obliquity, sharp angle, and necrotic location, following the guidelines of the Japanese Investigation Committee, were evaluated. Results: There were no significant differences in radiographic parameters between the 106 hips that underwent surgery and the 146 hips without surgery. Among the 167 hips without initial collapse, 91 eventually collapsed while 76 did not; their radiographic findings have no significant differences. The necrotic locations were significantly larger in hips requiring surgical intervention or femoral head collapse. Furthermore, 21.8% (55 out of 252 hips) had acetabular dysplasia, which did not significantly correlate with the necessity for surgical treatment or the incidence of femoral head collapse. Conclusions: Acetabular coverage has little effect on the necessity for surgical treatment and femoral head collapse in ONFH patients over a long-term follow-up. [ABSTRACT FROM AUTHOR]

When indicated, Birmingham Hip Resurfacing (BHR) presents a viable alternative to total hip arthroplasty (THA), but there remain questions about the long-term outcomes of BHR. Therefore, we asked: 1) what are the long-term patient-reported outcomes and 2) survivorship rates following BHR; 3) what are the causes for revision surgery after BHR? and 4) how have these outcomes compared to THA at long-term follow-up. A query of PubMed, MEDLINE, Scopus, and Cochrane in September 2023 was performed. Articles were included if they reported BHR survivorship rates at ≥10 years. Survivorship was defined as an all-cause revision of any BHR component. This review encompasses 26 articles, totaling 13,103 hips. Mean follow-up ranged from 6.0 to 20.9 years, but each study had at least a subgroup analysis for ≥10-year follow-up. Five studies compared preoperative and postoperative PROs for BHR, with four reporting improvement in at least one PRO after 10-year follow-up. Overall, survivorship rates ranged from 83% to 100% across diverse long-term timeframes, with 25 of 26 studies reporting 10-year survivorship rates greater than 87%. The primary reasons for revisions were implant loosening (22%), adverse reactions to metal debris (21.2%), and fractures of any kind (17.2%). In the six studies that compared BHR to THA, long-term survivorship was similar while BHR exhibited slightly superior activity levels. The findings from this study suggested favorable long-term survivorship and postoperative outcomes of BHR. In studies comparing long-term BHR and THA, survivorship was comparable, with BHR potentially providing enhanced postoperative activity levels. [ABSTRACT FROM AUTHOR]

Introduction: Aortic stenosis is a cause of mortality or morbidity. It complicates the selection and management of anesthetic procedures. The aim of this study was to evaluate the efficacy, hemodynamic effects and postoperative outcome of unilateral spinal anesthesia in geriatric patients with hip fractures with moderate or severe aortic stenosis. Material and Method: A retrospective observational study was conducted on geriatric high-risk patients with cardiac conditions who underwent surgery for hip fractures under unilateral spinal anesthesia with low-dose hyperbaric bupivacaine. The study period spanned from January 2018 to December 2021. The inclusion criteria were individuals with moderate to severe aortic stenosis, as defined by the American Heart Association Criteria. Data on demographic information, cardiac pathologies, hemodynamic data, data on motor and sensory block, perioperative complications, and mortality rates at 30th and 180th days were collected. Results: Mortality rates at the 30th day and 180th day were 8.9% (n:4) and 24.4% (n:11), respectively. T6 level was predominantly obtained level of anesthesia (44.4%). Motor and sensory block formation times averaged 7.6 and 4.8 minutes, respectively. Surgical procedures were performed mostly within 1 hour (66.7%), and complications were rare (11.1% hypotension). Initial analgesic effect showed a rapid resolution, with 64.4% of patients requiring analgesic within the first hour postoperatively. Conclusion: In elderly patients with moderate to severe aortic stenosis scheduled for hip fracture surgery, we posit that unilateral spinal anesthesia with ultra-low dose is safe and effective option.

Background: The Musculoskeletal Tumor Society Score (MSTS) is widely used to evaluate functioning following surgery for bone and soft-tissue sarcoma. However, concerns have been raised about its content validity due to the lack of patient involvement during item development. Additionally, literature reports inconsistent results regarding data quality and structural validity. This study aimed to evaluate content, structural and construct validity of the Danish version of the MSTS for lower extremity (MSTS-LE). Methods: The study included patients from three complete cohorts (n = 87) with bone sarcoma or giant cell tumour of bone who underwent bone resection and reconstruction surgery in hip and knee. Content validity was evaluated by linking MSTS items to frameworks of functioning, core outcome sets and semi-structured interviews. Data quality, internal consistency and factor analysis were used to assess the underlying structure of the MSTS. Construct validity was based on predefined hypotheses of correlation between the MSTS and concurrent measurements. Results: Content validity analysis revealed concerns regarding the MSTS. The MSTS did not sufficiently cover patient-important functions, the item Emotional acceptance could not be linked to the framework of functioning, the items Pain and Emotional acceptance pertained to domains beyond functioning and items' response options did not match items. A two-factor solution emerged, with the items Pain and Emotional acceptance loading highly on a second factor distinct from functioning. Internal consistency and construct validity showed values below accepted levels. Conclusion: The Danish MSTS-LE demonstrated inadequate content validity, internal consistency, and construct validity. In addition, our analyses did not support unidimensionality of the MSTS. Consequently, the MSTS-LE is not a simple reflection of the construct of functioning and the interpretation of a sum score is problematic. Clinicians and researcher should exercise caution when relying solely on MSTS scores for assessing lower extremity function. Alternative outcome measurements of functioning should be considered for the evaluation of postoperative function in this patient group. [ABSTRACT FROM AUTHOR]

Background/Objectives: The increasing numbers of already endemic hip fractures in the elderly taking anticoagulants is a growing concern for daily surgical practice. Ample evidence demonstrates decreased morbidity and mortality in the general population when surgery is performed at the earliest possibility. Direct anticoagulants are relatively new drugs that can cause increased perioperative bleeding. Current guidelines propose stopping the drug to allow for elimination before performing elective surgery. Optimal management in urgent hip surgery is presently based on expert opinion with arbitrary cut-offs. In this study, we investigated whether patients taking direct anticoagulants would benefit from early surgical treatment, regardless of the timing since last intake. Methods: A total of 340 patients were included in the analysis, of which 59 took direct anticoagulants. The primary outcomes were time to surgery, postoperative transfusion rate, postoperative hemoglobin decrease, length of postoperative in-hospital stay (LOPS), revision rate, and complication rate (medical and surgical). Results: Our findings showed that the anticoagulated group was fit for discharge earlier when operated on within 24 h (p = 0.0167). Postoperative transfusion and medical complication rate tended to be lower when the operation was performed earlier. Revision rate due to hematomas were higher in the direct anticoagulant group without a relationship to time to surgery. Simple linear regression could not determine a relationship between postoperative hemoglobin change and time to surgery. Conclusions: We suggest that directly anticoagulated patients needing hip fracture surgery must be considered for early surgery. [ABSTRACT FROM AUTHOR]

Purpose: It is not uncommon for patients with hip disorders to present with pelvic obliquity (PO), and residual PO after total hip arthroplasty (THA) may not only affect hip joint function but also cause adjacent intervertebral joint disorders. This study aimed to investigate the postoperative PO impact on clinical outcomes and risk factors by comparing patients who had PO after THA to those who did not. Methods: A single-center, retrospective cohort study was conducted. A total of 103 patients who underwent THA were included in this study from 2018 to 2020. Demographics, functional outcomes, and spinopelvic parameters were compared between post-THA PO of less than 2° (NT group, 55 patients) and PO of 2° or more (O group, 48 patients). Multivariate analysis was performed using factors with significant differences in univariate analysis. Results: Postoperative Harris Hip Score Activity was significantly lower in the T group than in the NT group (p = 0.031). Preoperative PO was smaller in the NT group than in the T group (p = 0.001). Preoperative lumbar bending range (LBR) was significantly more flexible in the NT group than in the T group. In the logistic regression analysis, Age (odds ratio 0.957, 95% CI 0.923–0.993, p = 0.020), preoperative PO (odds ratio 1.490, 95% CI 1.100–2.020, p = 0.001), and LBR (odds ratio 0.848, 95% CI 0.756–0.951, p = 0.005) were found to be significant factors. Conclusion: Younger age and large preoperative PO, and poor lumbar spine mobility were identified as risk factors for residual postoperative PO. [ABSTRACT FROM AUTHOR]

Background: Hip replacement surgery is highly effective in relieving pain and improving mobility in patients with various hip conditions. However, some patients develop groin pain after surgery, often due to iliopsoas impingement (IPI), which can be challenging to diagnose. Conservative treatments are initially recommended, but when these are not effective, surgical options may be considered. This study aims to evaluate the clinical outcomes, success and failure rates, revision rates, and complications associated with arthroscopic and endoscopic surgery for IPI, thereby providing a comprehensive understanding of the effectiveness and risks of these surgical interventions. Materials and methods: A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, including a thorough search of five main databases: PubMed, Scopus, Embase, Medline, and Cochrane. Eligible articles were meticulously evaluated according to predefined criteria for levels of evidence (LoE), with retrospective studies assessed using the Coleman Methodology Score (mCMS). This systematic review was registered in the International Prospective Registry of Systematic Reviews (PROSPERO). Results: Among the 16 included studies, 431 patients with 434 hips underwent either endoscopic or arthroscopic tenotomy. Both techniques showed favorable outcomes, with arthroscopic tenotomy demonstrating slightly higher success rates than endoscopic tenotomy. Common complications included mild pain and occasional infections, with recurrence observed in some cases. Both techniques offer direct visualization of prosthetic components and potential preservation of psoas function. Conclusions: Arthroscopic and endoscopic iliopsoas tenotomy are effective treatments for alleviating symptoms and improving hip function in patients with IPI post-total hip arthroplasty (THA). Level of evidence: IV. [ABSTRACT FROM AUTHOR]

Background: Snapping hip syndrome (SHS) is characterized by snapping sensation and pain and affects up to 10% of the general population. External snapping hip syndrome (ESHS), the most common form, is often due to repetitive movements in sports or anatomical predispositions. Conservative treatment includes physiotherapy and corticosteroid injections, while surgery is considered if conservative measures fail. Open surgical techniques carry several risks, while modern arthroscopic techniques offer less invasive options, such as endoscopic iliotibial band release (ITB) and gluteus maximus tenotomy. Materials and methods: A systematic review was conducted adhering to the PRISMA guidelines. Relevant studies were searched in four databases: Pubmed, Scopus, Embase, and Medline. The selected articles were evaluated according to the criteria of levels of evidence. The Risk of Bias In Non-randomized Studies of Interventions (ROBINS-I) was used to analyze the retrospective studies. This paper was registered in the International Prospective Registry of Systematic Reviews (PROSPERO). Results: Out of 9 included studies, 403 patients with 689 hips underwent endoscopic treatment. ITB release and his variations were the main surgical techniques. Gluteus maximus tenotomy was also used in some studies. Postoperative rehabilitation protocols varied. Patients generally experienced significant improvements in symptoms and functional outcomes, with low rates of recurrence (1.02%) and revision (0.15%). Complications were minimal. Conclusions: Endoscopic treatment of ESH shows favorable results, improving functional outcomes and returning patients to pre-injury activity levels. Long-term efficacy and costeffectiveness need to be evaluated, emphasizing the importance of large-scale prospective randomized trials to clarify surgery's benefits in refractory ESH cases.

Background: Greater trochanteric pain syndrome (GTPS) presents challenges in clinical management due to its chronic nature and uncertain etiology. Historically attributed to greater trochanteric bursitis, current understanding implicates abductor tendinopathy as the primary cause. Diagnosis usually involves a clinical examination and additional tests such as imaging and provocative testing. Surgical intervention may be considered for cases refractory to conservative therapy, with endoscopic techniques gaining ground over open procedures. Materials and methods: A systematic review was conducted adhering to the PRISMA guidelines. Relevant studies were searched in four databases: Pubmed, Scopus, Embase, and Medline. The selected articles were evaluated according to the criteria of levels of evidence (LoE). The Coleman methodology score (mCMS) was used to analyze the retrospective studies. This systematic review was registered in the International Prospective Registry of Systematic Reviews. Results: Surgical success rates ranged from 70.6–100%, significantly improving pain and function. Complications were generally mild, mainly hematomas and seromas, while recurrence rates were low. However, limitations such as the retrospective design and the absence of control groups warrant cautious interpretation of the results. Conclusions: Endoscopic surgery emerges as a promising option for refractory GTPS, offering effective symptom relief and functional improvement. Despite limitations, these results suggest a favorable risk–benefit profile for endoscopic procedures. Further research is needed, particularly prospective randomized trials, to confirm these findings and optimize surgical techniques to improve patient outcomes. [ABSTRACT FROM AUTHOR]

Background: The progression of scoliosis has been observed in skeletally mature patients with cerebral palsy (CP). The aims of this systematic review were to determine the incidence of curve progression of untreated scoliosis after skeletal maturity, to estimate the average annual increase and to identify factors that influence the progression. Methods: A systematic literature search was performed in PubMed, Embase and the Cochrane Library for original research articles published between 1968 and May 2024 with a retrospective, prospective or cross-sectional design, investigating CP patients that were followed up beyond the age of 15 years. The search was limited to articles in English, French, German and Dutch. Articles were excluded if the study population concerned neuromuscular diseases other than CP. After an assessment of the methodological quality of each study, estimates of annual curve progression and the effect of the investigated risk factors for progression were recorded systematically and synthetized. Results: Fifteen studies met the inclusion criteria, resulting in a total sample size of 2569 participants. The study populations of the included original research articles were small and heterogeneous in terms of patient age and the type and severity of CP. Curve progression after skeletal maturity occurred in all included studies. A greater curve magnitude at the end of adolescence and a severe motor deficit (an inability to walk or GMFCS IV-V) were identified as significant risk factors for the progression of scoliosis after skeletal maturity. If at least one of these risk factors was present, scoliotic curves progressed after skeletal maturity in up to 74% of patients, with an average annual increase of 1.4 to 3.5 degrees per year. No significant association was found between curve progression and the physiologic type of CP, the type of scoliotic curve, previous hip surgery, positioning and gravity, weight and length, sex, epilepsy, or pelvic obliquity. Findings on the effect of hip instability were inconsistent: a positive correlation was found with the progression of scoliosis overall, but not after skeletal maturity in particular. A significant selection bias should be considered in the calculation of average annual curve progression, as patients that received interventions to halt curve progression were excluded from follow-up. Conclusions: The identification of risk factors in patients with CP and scoliosis can aid in predicting curve progression and managing follow-ups in clinical practice. Based on the findings in this review a radiographic follow-up once every 3 years is recommended for skeletally mature CP patients with at least one risk factor, and once every 5 years if no risk factors are present.

In this retrospective cohort study, we investigated: (1) The impact of comorbid chronic kidney disease (CKD) on postoperative mortality in patients with a hip fracture; (2) mortality variations by dialysis type, potentially indicating CKD stage; (3) the efficacy of different hip fracture surgical methods in reducing mortality for patients with CKD. This study included 25,760 patients from the Korean National Health Insurance Service-Senior cohort (2002–2019) who underwent hip fracture surgery. Participants were categorized as CKD and Non-CKD. Mortality rate was determined using a generalized linear model with a Poisson distribution. The effect size was presented as a hazard ratio (HR) through a Cox proportional-hazard model. During follow-up, we ascertained that 978 patients (3.8%) had CKD preoperatively. Compared to the Non-CKD group, the mortality risk (HR) in the CKD group was 2.17 times higher (95% confidence interval [CI], 1.99–2.37). In sensitivity analysis, the mortality risk of in patients who received peritoneal dialysis and hemodialysis was 6.21 (95% CI, 3.90–9.87) and 3.62 times (95% CI, 3.11–4.20) higher than that of patients who received conservative care. Mortality risk varied by surgical method: hip hemiarthroplasty (HR, 2.11; 95% CI, 1.86–2.40), open reduction and internal fixation (HR, 2.21; 95% CI, 1.94–2.51), total hip replacement (HR, 2.27; 95% CI, 1.60–3.24), and closed reduction and percutaneous fixation (HR, 3.08; 95% CI, 1.88–5.06). Older patients with CKD undergoing hip fracture surgery had elevated mortality risk, necessitating comprehensive pre- and postoperative assessments and management. [ABSTRACT FROM AUTHOR]

Septic arthritis of the hip joint (septic hip) is the bacterial infection of the hip. Delayed treatment increases the risk of extensive joint damage, systemic infection, prolonged recovery, higher healthcare costs, and long-term disability. This study explores the repercussions of delayed surgical treatment in pediatric septic hip. In this observational study, pediatric patients diagnosed with septic hip between 2012 and 2021 were retrospectively selected from a major referral center in Shiraz, Iran. We collected clinical and radiological data, including Kocher score and determined Choi classification in follow-up radiographs. Multivariate logistic regression analysis was used to assess the impact of delay to surgery on the development of clinical sequelae and radiological deformities in the presence of potential confounders of age and Kocher criteria. Out of 49 children with delayed presentation, 46 survived and entered the study. Mean delay from symptom presentation to admission was 12.67 ± 10.51 days, and mean delay from admission to surgery was 5.33 ± 6.47 days. Of the 46 patients, 28.26% developed clinical sequelae. The Choi classification revealed that 54.35% of patients developed no residual deformity. A multivariate logistic regression analysis indicated a statistically significant association between delay to surgery and the development of radiological deformities (adjusted odds ratio: 1.36, 95% CI: 1.14–1.64, p = 0.001). Additionally, a separate analysis revealed that each additional day of delay was associated with a 12% increase in the odds of clinical sequelae (adjusted odds ratio: 1.12, 95% CI: 1.03–1.22, p = 0.006). Sensitivity analyses confirmed the relationship of delay from admission to surgery in developing both outcomes. Delay in medical care and surgical management remains the most important factor affecting the outcomes of septic hip. The study underscores the critical role of timely surgical intervention in reducing complications in pediatric septic hip patients. [ABSTRACT FROM AUTHOR]

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.

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.

Background: Postoperative pain remains a significant challenge after knee and hip surgeries, two of the most frequently performed procedures, preventing patients from seeking timely surgical help. Gabapentinoids, gabapentin, and pregabalin, have been gaining attention in postoperative pain management. Methods: We conducted a meta-analysis to evaluate the efficacy of gabapentinoids in pain management after knee and hip surgery. PubMed, Scopus, and Cochrane Library were searched for relevant randomized controlled trials (RCTs) published before January 2023. Results: Fifteen articles reporting 1320 patients were analyzed. Cumulative pain intensity at rest and on movement was lower in the experimental group with the mean difference (MD) = −0.30 [−0.55,−0.05], p-value = 0.02, and MD = −0.41 [−0.68,−0.13], p-value = 0.004, respectively. However, the difference was not clinically meaningful and lacked statistical significance at each time period. The gabapentinoid group required less opioid consumption in morphine equivalents (MD = −6.42 [−9.07, −3.78] mg, p-value < 0.001). There was a lower incidence of postoperative nausea in the experimental group with a risk ratio (RR) of 0.69 [0.55, 0.86], p-value < 0.001. A subgroup analysis showed that gabapentinoids reduced pain on movement on postoperative day two after total knee arthroplasty but not hip arthroplasty. There was insufficient data to examine the efficacy of gabapentinoids in the reduction of chronic postoperative pain in knee/hip surgery. Conclusions: Thus, gabapentinoids were associated with a reduction in postoperative pain intensity at rest and on movement, morphine consumption, and the incidence of postoperative nausea in the early postoperative period following knee and hip surgeries. However, pain reduction was not clinically relevant. Sedation has not been evaluated in this work and, if performed, this may have influenced the conclusions. An important limitation of this study is that different gabapentinoids, their administration times and dosages, as well as varying intraoperative management protocols, were pooled together.

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.

Background: Previous studies have shown that short-term outcomes after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) predict midterm outcomes, but a limited number of studies have evaluated whether short-term outcomes predict long-term outcomes and survivorship. Purpose: To evaluate whether achieving clinically significant outcomes at 2 years after hip arthroscopy for FAIS can predict patient-reported outcomes (PROs) and survivorship at 10 years. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent primary hip arthroscopy for FAIS between June 2012 and December 2012 with a minimum 10-year follow-up were identified. Using previously established thresholds, we classified patients who achieved the 2-year Patient Acceptable Symptom State (PASS) for the visual analog scale (VAS) for satisfaction as the high satisfaction group and patients who did not as the low satisfaction group. Minimum 10-year PROs were then compared between the groups, including scores for the Hip Outcome Score (HOS)–Activities of Daily Living and –Sports Specific, the modified Harris Hip Score, the VAS for pain, and the VAS for satisfaction. Reoperation-free survivorship was compared. Results: Of 120 eligible consecutive patients, 85 patients were included (70.8% follow-up rate), of whom 61.2% were female. The mean age was 34.0 ± 12.8 years, and the mean body mass index was 25.4 ± 4.6. Of the 85 patients, 29 (34.1%) did not achieve PASS for the VAS for satisfaction at 2 years postoperatively compared with 56 (65.9%) who did. The low satisfaction group had significantly worse acetabular chondral grades at the time of surgery (P =.008). At minimum 10-year follow-up, the high satisfaction group showed significantly better HOS-Activities of Daily Living, HOS-Sports Specific, modified Harris Hip Score, VAS pain, and VAS satisfaction scores (P ≤.031). Compared with the low satisfaction group, the high satisfaction group had a significantly lower rate of secondary surgery (1.8% vs 24.1%, respectively; P =.002). Conclusion: Patients who achieved PASS for the VAS for satisfaction at 2 years after hip arthroscopy demonstrated superior minimum 10-year outcomes compared with patients who did not, including greater PRO scores and a higher survivorship rate. The high satisfaction group had lower grade acetabular cartilage damage at the time of surgery compared with those who did not achieve PASS for the VAS for satisfaction at 2 years.

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.

Background Methods Results Conclusion Studies have demonstrated beneficial outcomes associated with timely surgical treatment of hip fracture. Subsequently, practice recommendations changed with 24–48 h as the recommended time for surgery from admission; however, recent data on timing of hip fracture surgery and how this impacts outcomes are lacking.This retrospective cohort study included patients who had a primary diagnosis of hip fracture and underwent a subsequent surgical repair within 3 days of admission (Premier Healthcare claims 2006–2021 data). The primary exposure of interest was time from hip fracture diagnosis to surgery (categorized as 0–1 day, 2 days, and 3 days). Outcomes included any major complication, mortality, and intensive care unit (ICU) admission. Mixed‐effects models measured the association between timing of surgery and outcomes. We report odds ratios (OR) and 95% confidence intervals.Among 501,267 surgical hip fracture patients, 26.0%, 56.0%, and 18.1% of patients received surgery on days 0–1, 2, and 3, respectively. The median ages were 83, 84, and 84 years old, and there were 73.3%, 72.2%, and 68.8% female in each group respectively. Compared with repair on day 0–1, hip fracture surgical treatment on day 2 or day 3 was associated with increased odds of major complications (OR 1.06, 95% CI 1.03–1.08 and OR 1.17, 95% CI 1.13–1.2), mortality (OR 1.08, 95% CI 1.02–1.14 and OR 1.2, 95% CI 1.12–1.28), and ICU admission (OR 1.06, 95% CI 1.04–1.09 and OR 1.36, 95% CI 1.32–1.4) after adjusting major comorbidities; all p < 0.001.Despite the publication of society guidelines in 2015, most fracture patients still received surgery on day 2 or day 3 of admission and were associated with worse outcomes. Balancing optimization of clinical factors with timing of surgery can be challenging, and further research is needed. Nonetheless, our findings reiterate the importance of timely surgical intervention. [ABSTRACT FROM AUTHOR]

Background: The increasing amount of revision surgeries in total hip arthroplasty (THA) represents a burden for orthopedic surgeons given the complexity and unpredictability of this kind of surgery. The aim of the current study was to develop a new radiographic classification of acetabular bone defects stratify the severity of the lesion and to suggest the surgical strategy to address it. Methods: Radiographs of 151 consecutive patients who underwent acetabular revision surgery in our institution were collected to develop a new classification that groups the acetabular bone defects in three zones (A, B and C). The performance to predict treatment and inter- and intra-rater agreement were evaluated. Results: The ability of the newly proposed classification to predict treatment was 87.3% (k weighted: 0.65). The inter-rater reliability was 90.1% (k: 0.81), and the intra-rater reliability between the two sets of evaluations performed by the observer at 1-month distance was 97.5% (k: 0.94). Conclusions: The newly proposed classification was able to characterize the extent of acetabular bone defects and predict pre-operatively the appropriate surgical treatment strategy in 87.3% of cases. It showed a strong agreement among raters and an almost perfect agreement among different measurements at 1 month distance. This new tool could be used in the preoperative assessment to drive the use of secondary level image examinations and the type of surgical management. [ABSTRACT FROM AUTHOR]

Background/Aim. Surgery for developmental dysplasia of the hip (DDH) often needs acetabuloplasty and femoral osteotomy. This type of operation is characterized by long duration, major trauma, and severe postoperative pain. The aim of the study was to compare the analgesic effects of the caudal block (CB) and epidural block (EB) on the DDH surgery in children. Methods. A total of 100 children undergoing DDH surgery in our hospital from May 2018 to December 2021 were selected and randomly divided into two groups: an ultrasound-guided CB group and an EB group (each group consisting of 50 children). The dosage of ropivacaine, changes in blood pressure, heart rate, and intraoperative dosage of fentanyl were recorded. In addition, we recorded the values of several parameters after the surgery: the modified Face, Legs, Activity, Cry, and Consolability (FLACC) scale score at 2, 4, 6, 12, 24, 36, and 48 hrs after surgery; the time point of first-time request for acetaminophen and proportion of patients using pethidine; the sedation degree within 12 hrs after the operation (assessed using the Ramsay Sedation Scale -- RSS); the incidence of nausea, vomiting, and urinary retention; the satisfaction degree of family members with the applied methods of postoperative analgesia in children. Results. The ropivacaine dosage used in the CB group exceeded that of the EB group (p < 0.05). The CB group had lower FLACC scores 12 and 24 hrs after the operation and a longer postoperative time until the first-time request for acetaminophen than the EB group (p < 0.05). No block-related complications occurred; the two groups had similar incidence rates of nausea, vomiting, and urinary retention. The RSS score within 12 hrs after operation was higher in the CB group than in the EB group, and the family members of the children in the CB group were more satisfied (p < 0.05). Conclusion. Both CB and EB can provide satisfactory intraoperative and postoperative analgesia for pediatric hip surgery. However, CB provides effective analgesia for 24 hrs after the operation and lasts longer than that accomplished by the EB. [ABSTRACT FROM AUTHOR]

(1) Background: Hip fractures are currently recognized as major public health problems, raising many issues in terms of both patients' quality of life and the cost associated with caring for this type of fracture. Many authors debate whether to operate as soon as possible or to postpone surgery until the patient is stable. The purpose of this review was to review the literature and obtain additional information about the moment of surgery, the time to surgery, length of hospital stay, and how all of these factors influence patient mortality and complications. (2) Methods: The systematic search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and PICO guidelines, using the Google Scholar platform, for articles published between 2015 and 2023. Quality assessment was performed. (3) Results: After applying the inclusion criteria, 20 articles were included in the final list. Those who had surgery within 48 h had lower in-hospital and 30-day mortality rates than those who operated within 24 h. The American Society of Anesthesiologists (ASA) score is an important predictive factor for surgical delay, length of hospital stay (LOS), complications, and mortality. (4) Conclusions: Performing surgery in the first 48 h after admission is beneficial to patients after medical stabilization. Avoidance of delayed surgery will improve postoperative complications, LOS, and mortality. [ABSTRACT FROM AUTHOR]

Introduction: Extra-articular hip resection may be necessary in cases of malignant tumour of the pelvic bone or of the proximal femur invading the hip joint. When the tumour is in the proximal femur, it is possible to resect the acetabulum en bloc by performing a periacetabular osteotomy, but this creates a discontinuity in the pelvic ring with difficult reconstruction and diminished function. Several techniques described recently seek to be as sparing as possible on the pelvic bone by preserving the posterior column or both columns in order to facilitate reconstruction and improve function. However, these still require complex reconstructions and can necessitate intra-pelvic dissection. Technique: We describe here an extra-articular hip resection technique for tumours of the proximal femur invading the joint, with maintenance of pelvic continuity by preserving both columns and the quadrilateral plate of the acetabulum, without intra-pelvic dissection, that can be performed on patients in whom the medial wall of the acetabulum is thick enough. Our preliminary assessments have included studies on dry bone and imaging analyses. The technique was first tested on a single cadaver pelvis (encompassing 2 hips) and subsequently performed on a patient with a pathological fracture of the femoral neck due to osteosarcoma secondary to Paget's disease. Conclusions: Further clinical applications are essential to evaluate the overall effectiveness, safety and impact on patient functionality of this experimental technique. [ABSTRACT FROM AUTHOR]

Background and Aims: Postoperative pain after hip surgeries in children could be classified as severe, requiring combined intra- and postoperative opioid analgesia with regional blocks. This study was carried out to investigate ultrasound-guided pericapsular nerve group (PENG) block versus ultrasound-guided erector spinae plane (ESP) block for pain management after paediatric hip surgery. The primary objective was to assess the time of the first request for morphine rescue analgesia. Methods: In this randomised study, 56 children scheduled for elective unilateral hip surgery were distributed randomly to ESP and PENG groups. Intraoperative haemodynamics, fentanyl consumption, postoperative pain measurement, morphine consumption, time of first rescue analgesia, adverse effects and parents' satisfaction score were studied. The primary outcome was the time of the first request for morphine rescue analgesia. The Chi-square test, Student's t-test and the Mann--Whitney U test were used, where applicable, to compare the groups. Results: The time to first rescue analgesia was significantly longer in Group ESP than in Group PENG (P < 0.001), with significantly higher postoperative morphine consumption in Group PENG than in Group ESP (P = 0.04). The pain scores of Group ESP were lower than those of Group PENG at 2 and 4 h postoperatively (P = 0.006 and P < 0.001, respectively). At 8 h postoperatively, the score was significantly higher in Group ESP than in Group PENG (P = 0.005). Other outcomes were comparable between both groups (P > 0.05). Conclusion: ESP and PENG could be both effective for intraoperative and postoperative analgesia in paediatric hip surgeries, but the ESP block prolonged the time of first rescue analgesia more than the PENG block.

Objective: To assess the performance of morphologic and hypointense signal changes on MRI to predict grades and types of acetabular cartilage damage in the chondrolabral transitional zone (TZ) of the hip identified at arthroscopy. Materials and methods: This retrospective single-center study reviewed conventional 3T MRI hip studies from individuals with symptomatic femoroacetabular impingement (FAI) and subsequent hip arthroscopy surgery within 6 months. Independent review was made by three radiologists for the presence of morphologic damage or a hypointense signal lesion in the TZ on MRI. Fleiss' kappa statistic was used to assess inter-reader agreement. The degree of TZ surfacing damage (modified Outerbridge grades 1–4) and presence of non-surfacing wave sign at arthroscopic surgery were collected. Relationship between sensitivity and lesion grade was examined. Results: One hundred thirty-six MRI hip studies from 40 males and 74 females were included (mean age 28.5 years, age range 13–54 years). MRI morphologic lesions had a sensitivity of 64.9–71.6% and specificity of 48.4–67.7% for arthroscopic surfacing lesions, with greater sensitivity seen for higher grade lesions. Low sensitivity was seen for wave sign lesions (34.5–51.7%). MRI hypointense signal lesions had a sensitivity of 26.3–62% and specificity of 43.8–78.0% for any lesion. Inter-reader agreement was moderate for morphologic lesions (k = 0.601) and poor for hypointense signal lesions (k = 0.097). Conclusion: Morphologic cartilage damage in the TZ on MRI had moderate sensitivity for any cartilage lesion, better sensitivity for higher grade lesions, and poor sensitivity for wave sign lesions. The diagnostic value of hypointense signal lesions was uncertain. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the distribution of intra- and extraarticular MRI findings in children and adolescents with clinically suspected intraarticular cause of hip pain in order to assess the need for additional intraarticular contrast administration. Material and methods: Database was searched over a period of 34 months retrospectively for consecutive hip MR arthrography in young patients (8–17 years) with suspected intraarticular cause of hip or groin pain. Exclusion criteria were prior hip surgery, follow-up examination due to known intraarticular pathology, incomplete examination, qualitatively non-diagnostic examinations, and missing informed consent. Reports of fellowship-trained MSK radiologists were searched for intraarticular versus extraarticular findings explaining hip or groin pain. Results: Seventy patients (68% female; median age: 14.5 years; range:10.8–16.9 years) were analyzed. No reason for pain was found in 30 (42.9%) hips, extraarticular reasons in 20 (28.6%) cases, intraarticular in 14 (20.0%), and both (intra- and extraarticular) in 6 (8.6%) hips. Most common extraarticular reasons were apophysitis (14.3%), other bony stress reactions (12.9%), intramuscular edema (7%), tendinitis (5.7%), and trochanteric bursitis (4.3%). Labral pathology was the most common intraarticular finding (overall:34.3%; partial tear:15.7%, complete tear:15.7%), most frequent at the anterosuperior position (81.8%). Cartilage defects (1.4%), intraarticular neoplasia (1.4%), and tear of the femoral head ligament (2.8%) were rarely found. Synovitis and loose bodies were not observed. Cam-(37.1%) and pincer-configurations (47.1%) were common while hip dysplasia was rare (5.7%). Conclusion: MRI in children and adolescents with hip pain should be done primarily without intraarticular contrast administration since most cases show an extraarticular pain reason or no diagnosis detectable with MRI.

Background: Although hip arthroscopy has been shown to have beneficial outcomes, there is a paucity of literature examining predictive factors of 10-year clinical outcomes. Purpose: (1) To identify predictive factors of 10-year outcomes of hip arthroscopy and (2) to compare these factors with those found in 2-year and 5-year studies. Study Design: Cohort study; Level of evidence, 3. Methods: Data were prospectively collected and retrospectively reviewed on all patients undergoing hip arthroscopy between February 2008 and June 2012. Patients were included if they had a minimum 10-year follow-up on 2 patient-reported outcome measures: Nonarthritic Hip Score (NAHS) and modified Harris Hip Score. Exclusion criteria included previous ipsilateral hip conditions. Using bivariate and multivariate analyses, that authors analyzed the effects of 37 pre- and intraoperative variables on the NAHS, modified Harris Hip Score, and conversion to total hip arthroplasty. Results: Of the 883 patients who met the inclusion criteria, 734 (83.1%) had follow-up data. The mean follow-up time was 124.4 months (range, 120.0-153.1 months). Six variables were significant predictors of NAHS in both multivariate and bivariate analyses: revision status, body mass index (BMI), duration of symptoms, preoperative NAHS, age at onset of symptoms, and need for acetabular microfracture. Positive predictors of 10-year survivorship included acute injury and gluteus medius repair, while negative predictors included revision arthroscopy, Tönnis grade, acetabular inclination, iliopsoas fractional lengthening, and notchplasty Conclusion: Multiple predictive factors including age, BMI, revision status, and preoperative outcome scores were identified for long-term survivorship and functional outcomes. These may prove useful to clinicians in refining indications and guiding patients on expected outcomes of hip arthroscopy. [ABSTRACT FROM AUTHOR]

Background: Physical therapy is frequently utilized in the postoperative care of femoroacetabular impingement syndrome (FAIS). There has been limited research into the efficacy of a structured home exercise program (HEP) compared with formal physical therapy (FPT) in this patient population. Purpose/Hypothesis: The purpose was to evaluate the short-term outcomes of patients utilizing FPT versus an HEP after hip arthroscopic surgery for FAIS. It was hypothesized that both groups would show similar improvements regarding outcome scores, which would improve significantly compared with their preoperative scores. Study Design: Cohort study; Level of evidence, 2. Methods: Patients undergoing hip arthroscopic surgery for FAIS at a single center between October 2020 and October 2021 were prospectively enrolled. Patients were allowed to self-select FPT or an HEP and were administered a survey preoperatively and at 1 month, 3 months, 6 months, and 12 months postoperatively. The survey included the Single Assessment Numeric Evaluation, visual analog scale for pain, 12-item International Hip Outcome Tool, Patient-Reported Outcomes Measurement Information System Physical Function, and patient satisfaction with physical therapy and overall care. Statistical analysis was conducted between the 2 groups and within groups to compare preoperative and postoperative scores. Results: The patients' mean age was 32.6 ± 10.4 years, with 47.2% being female and 57.4% choosing the HEP. At 12 months postoperatively, no significant differences were reported between the FPT and HEP groups regarding the Single Assessment Numeric Evaluation score (P =.795), visual analog scale for pain score (P >.05), Patient-Reported Outcomes Measurement Information System Physical Function T-score (P =.699), 12-item International Hip Outcome Tool score (P =.582), and patient satisfaction (P >.05). Outcome scores at 12 months postoperatively were significantly improved from the preoperative scores across all measures in both groups (P <.001). Conclusion: There were no significant differences regarding patient outcomes between FPT and the HEP at 1-year follow-up after hip arthroscopic surgery for FAIS when patients selected their own treatment, with both groups demonstrating significant improvements in their outcome scores from their preoperative values. These findings suggest that a structured HEP may be a viable alternative to FPT after hip arthroscopic surgery in patients who prefer a self-directed rehabilitation program. [ABSTRACT FROM AUTHOR]

Background: There is a paucity of literature evaluating long-term outcomes and survivorship of patients undergoing primary hip arthroscopy with capsular repair for femoroacetabular impingement syndrome (FAIS). Purpose: To report 10-year survivorship and patient-reported outcomes (PROs) after primary hip arthroscopy with capsular repair for FAIS and evaluate the effect of capsular repair in patients at the highest risk for conversion to arthroplasty. Study Design: Cohort study; Level of evidence, 3. Methods: Data were prospectively collected and retrospectively reviewed on all patients undergoing primary hip arthroscopy with capsular repair between October 2008 and February 2011. Patients with a minimum 10-year follow-up on the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and visual analog scale for pain (VAS) scores were selected. The preoperative and minimum 10-year follow-up Hip Outcome Score—Sports Specific Subscale (HOS-SSS) scores were also reported, if available. Patients with ipsilateral hip surgery, worker's compensation, Tönnis osteoarthritis grade >1, and hip dysplasia (lateral center-edge angle <25°) were excluded. Survivorship, PROS, and clinical benefit—minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS)—were reported. An additional propensity-matched subanalysis was performed on patients at the highest risk for conversion to arthroplasty, comparing patients undergoing capsular repair to patients with unrepaired capsules. Results: A total of 145 (n = 130 patients) out of 180 eligible hips (n = 165 patients) had a minimum 10-year follow-up (80.6%). Also, 126 hips (86.9%) belonged to women, and 19 hips (13.1%) belonged to men. The mean patient age was 30.3 ± 12.9 years. The survivorship rate was 91% at the 10-year follow-up. The cohort experienced significant improvements (P <.001) in the mHHS, NAHS, HOS-SSS, and VAS for pain scores. Moreover, the cohort achieved high rates of the PASS for the mHHS (89.8%), high rates of the MCID for the mHHS (82.4%), and high rates of the MCID for VAS for pain (80.6%) scores. In the propensity-matched subanalysis performed on patients with the highest risk for arthroplasty, 29 hips with capsular repair were matched to 81 hips with unrepaired capsules. While both groups experienced significant improvements in all PROs (P <.05), the group without capsule repair trended toward a higher conversion to arthroplasty rate when compared with the repair group. In addition, an odds ratio was calculated for the likelihood of converting to arthroplasty after having an unrepaired capsule compared with capsular repair (2.54 [95% CI, 0.873-7.37]; P =.087). Conclusion: Patients undergoing primary hip arthroscopy with capsular repair experienced a high survivorship rate of 91% at a minimum 10-year follow-up. Patients who did not convert to arthroplasty saw favorable improvements in PROs and achieved high clinical benefit rates. In addition, among those patients at the highest risk for conversion to arthroplasty, a trend toward greater survivorship was observed with capsular repair. [ABSTRACT FROM AUTHOR]

Background: As a novel regional analgesic technique, ultrasound-guided pericapsular nerve group (PENG) block has some potential advantages, and we designed a randomized clinical trial (RCT) to investigate whether the ultrasound-guided PENG block combined with general anesthesia can better reduce stress response, maintain intraoperative hemodynamic stability, and reduce postoperative analgesia in elderly hip arthroplasty compared with ultrasound-guided suprainguinal fascia iliaca block (SIFIB) combined with general anesthesia. Methods: Seventy-four subjects were enrolled over an 8-month period (20 April 2023 to 31 December 2023). All patients were divided into the test group (group P) and the control group (group S) using the envelope as the randomization method. The test group was treated with preoperative ultrasound-guided PENG block analgesia combined with general anesthesia and the control group was treated with preoperative ultrasound-guided SIFIB analgesia combined with general anesthesia. The primary outcome selected was the patient Visual Analogue Scale (VAS) score at 12 h postoperatively. Results: After generalized estimating equations (GEE) analysis, there was a statistically significant difference in the main effect of postoperative VAS score in group P compared with group S (P = 0.009), the time effect of VAS score in each group was significantly different (P < 0.001), and there was no statistically significant difference in the group-time interaction effect (P = 0.069). There was no statistically significant difference in the main effect of intraoperative mean arterial pressure (MAP) change (P = 0.911), there were statistically significant differences in the time effect of MAP in each group (P < 0.001), and there were statistically significant differences in the interaction effect (P < 0.001). Conclusions: In summary, we can conclude that in elderly patients undergoing hip fracture surgery, postoperative analgesia is more pronounced, intraoperative hemodynamic parameters are more stable, and intraoperative stress is less induced in patients receiving SIFIB than in patients receiving PENG block.

Introduction: The aim of our study was to validate the original Charlson Comorbidity Index (1987) (CCI) and adjusted CCI (2011) as a prediction model for 30-day and 1-year mortality after hip fracture surgery. The secondary aim of this study was to verify each variable of the CCI as a factor associated with 30-day and 1-year mortality. Methods: A prospective database of two-level II trauma teaching hospitals in the Netherlands was used. The original CCI from 1987 and the adjusted CCI were calculated based on medical history. To validate the original CCI and the adjusted CCI, the CCI was plotted against the observed 30-day and 1-year mortality, and the area under the curve (AUC) was calculated. Results: A total of 3523 patients were included in this cohort study. The mean of the original CCI in this cohort was 5.1 (SD ± 2.0) and 4.6 (SD ± 1.9) for the adjusted CCI. The AUCs of the prediction models were 0.674 and 0.696 for 30-day mortality for the original and adjusted CCIs, respectively. The AUCs for 1-year mortality were 0.705 and 0.717 for the original and adjusted CCIs, respectively. Conclusions: A higher original and adjusted CCI is associated with a higher mortality rate. The AUC was relatively low for 30-day and 1-year mortality for both the original and adjusted CCIs compared to other prediction models for hip fracture patients in our cohort. The CCI is not recommended for the prediction of 30-day and 1-year mortality in hip fracture patients. [ABSTRACT FROM AUTHOR]

The article focuses on evaluating the short-term outcomes of using trabecular metal augments for reconstructing acetabular bone defects during revision total hip arthroplasty. Topics include the effectiveness of trabecular metal augments, postoperative Oxford Hip Scores, and the challenges of achieving hip center of rotation in revision surgeries.

Hip replacement surgery can be painful; postoperative analgesia is crucial for comfort and to facilitate recovery. Regional anaesthesia can reduce pain and postoperative opioid requirements. The role of ultrasound-guided suprainguinal fascia iliaca block for analgesia after elective total hip arthroplasty is not well defined. This randomised trial evaluated its analgesic efficacy. Consenting participants (134) scheduled for elective primary total hip arthroplasty under spinal anaesthesia were randomly allocated to receive ultrasound-guided fascia iliaca block with ropivacaine 0.5% or sham block with saline. The primary outcome was opioid consumption in the first 24 h after surgery. Additional outcomes included pain scores at 4, 8, 12, and 16 h, opioid-related side-effects (nausea, vomiting, pruritis), ability to perform physiotherapy on the first postoperative day, and physiotherapist-assessed quadriceps weakness. There were no significant differences in 24-h opioid consumption (block vs sham block, mean difference −3.2 mg oral morphine equivalent, 95% confidence interval −15.3 to 8.1 mg oral morphine equivalent, P =0.55) or any other prespecified outcomes. In patients undergoing primary total hip arthroplasty, ultrasound-guided suprainguinal fascia iliaca block with ropivacaine did not confer a significant opioid-sparing effect compared with sham block. There were no differences in other secondary outcomes including pain scores, opioid-related side-effects, or ability to perform physiotherapy on the first postoperative day. www.clinicaltrials.gov (NCT03069183).

Background: Greater trochanteric pain syndrome (GTPS) is a commonly diagnosed medical issue, yet there are little data assessing the relative morbidity of GTPS. We sought to characterize the morbidity on presentation of GTPS and compare it to that of patients with end-stage hip osteoarthritis awaiting total hip arthroplasty. We hypothesized that patients with GTPS would have morbidity similar to or worse than that of patients with osteoarthritis. Materials and Methods: This retrospective case-control study examined patient-reported outcome measures of 156 patients with GTPS (193 hips) and 300 patients with hip osteoarthritis before total hip arthroplasty (326 hips). Patients with secondary hip conditions or previous hip surgeries were excluded from the study. Patient-reported outcome measures were analyzed using an equivalence test and two one-sided t tests. Results: Equivalence in mean visual analog scale pain scores between GTPS and osteoarthritis was established with a tolerance margin of ±10. The difference in mean visual analog scale pain scores was 0.35 (95% CI, −0.86 to 0.16; P=.02). The Hip disability and Osteoarthritis Outcome Score Quality of Life was much worse for patients with GTPS, placed well outside of the ±10 tolerance margin, and the difference in mean scores was 1.72 (95% Cl, −2.17 to −1.26; P=.99). Equivalence in mean UCLA Activity scores between GTPS and osteoarthritis was established with a tolerance margin of ±5. The difference in mean UCLA Activity scores was 0.002 (95% CI, −0.45 to 0.43; P<.01). Conclusion: The morbidity and functional limitations of patients with GTPS were similar to those of patients undergoing total hip arthroplasty. GTPS remains a functional problem for patients, and clinicians and researchers should consider GTPS as seriously as hip osteoarthritis. [Orthopedics. 2024;47(4):205–210.] [ABSTRACT FROM AUTHOR]

Patient education is important as it gives patients a better understanding of the risks and benefits of medical and surgical interventions. Developing communication technologies have completely changed and enhanced patient access to medical information. The aim of this study was to evaluate available patient education materials (PEMs) regarding hip surgery on the websites of major hip societies and centers. The PEM from 11 selected leading hip centers and societies were evaluated with the following assessment tools: Flesch–Kincaid (FK) readability test, Flesch Reading Ease formula, Literature-Intelligence-Data-Analysis (LIDA) instrument and Discernibility Interpretability Sources Comprehensive Evidence Relevance Noticeable (DISCERN) tool. Videos were assessed using Patient Educational Video Assessment Tool (PEVAT). A total of 69 educational items, including 52 text articles (75.4%) and 17 videos (24.6%) were retrieved and evaluated. The median Interquartile Range (IQR) FK level of 52 text articles was 10.8 (2.2). The median (IQR) LIDA score of text articles by center was 45. According to the LIDA score, 60% of all website articles demonstrated high accessibility (LIDA score > 44). The median DISCERN score of text articles by center was 69. Overall, 52 (100%) of the text articles were deemed to be at 'good' quality rating or higher, and 23.2% (16 out of 69) of the articles had excellent quality. The mean PEVAT score for the 17 videos was 25 ± 1.9. Analysis of text and video articles from the 11 leading orthopedic surgery centers and societies demonstrated that by selecting a reliable source of information from main scientific societies and major centers in hip surgery, patients can find more accurate information regarding their hip conditions.

Context: Professional athletes showed excellent results after hip preserving procedures. However, there is still a lack of knowledge regarding the rate of return to activity and the rehabilitation time of recreational athletes. Thus, the aim of this study was to investigate factors that were associated with an extended return-to-activity time in nonprofessional athletes. Design: Retrospective, quantitative case-control study. Methods: This study included 47 cases (45 nonprofessional athletes), which were divided according to return-to-activity time (short term: 0.0-7.0 mo vs long term: >7.0 mo). The clinical outcome were evaluated with the modified Harris hip score, the nonarthritic hip score, the Western Ontario and McMaster Universities Osteoarthritis Index, and the University of California, Los Angeles activity score. For statistical analysis between both groups, an unpaired student t test and a paired Wilcoxon test were used. In addition, the sports behavior, intraoperative findings, and surgical procedures were also assessed. Results: After a mean follow-up of 4.3 years (±0.6; 3.4-5.6), the overall postoperative modified Harris hip score was 81.8 points, the nonarthritic hip score was 75.8 points, the Western Ontario and McMaster Universities Osteoarthritis Index was 36.7 points, and the University of California, Los Angeles activity score was 7.9. Compared with the preoperative results, all scores improved significantly (P < .001). Patients of the short-term return-to-activity group showed a higher preoperative activity diversity and, postoperatively, a higher rate in high-impact sports (P = .024). Conclusions: After mini-open arthrotomy for femoroacetabular impingement syndrome treatment, 92.5% of the recreational athletes returned to sports activity. The findings did not detect factors influencing the return-to-activity time. However, a higher preoperative diversity of activities and a shift to high-level impact sport activities might support a shorter rehabilitation. [ABSTRACT FROM AUTHOR]

Abstract Background Allogeneic Blood transfusion is common in hip surgery but is associated with increased morbidity. Accurate prediction of transfusion risk is necessary for minimizing blood product waste and preoperative decision-making. The study aimed to develop machine learning models for predicting perioperative blood transfusion in hip surgery and identify significant risk factors. Methods Data of patients undergoing hip surgery between January 2013 and October 2021 in the Peking Union Medical College Hospital were collected to train and test predictive models. The primary outcome was perioperative red blood cell (RBC) transfusion within 72 h of surgery. Fourteen machine learning algorithms were established to predict blood transfusion risk incorporating patient demographic characteristics, preoperative laboratory tests, and surgical information. Discrimination, calibration, and decision curve analysis were used to evaluate machine learning models. SHapley Additive exPlanations (SHAP) was performed to interpret models. Results In this study, 2431 hip surgeries were included. The Ridge Classifier performed the best with an AUC = 0.85 (95% CI, 0.81 to 0.88) and a Brier score = 0.21. Patient-related risk factors included lower preoperative hemoglobin, American Society of Anesthesiologists (ASA) Physical Status > 2, anemia, lower preoperative fibrinogen, and lower preoperative albumin. Surgery-related risk factors included longer operation time, total hip arthroplasty, and autotransfusion. Conclusions The machine learning model developed in this study achieved high predictive performance using available variables for perioperative blood transfusion in hip surgery. The predictors identified could be helpful for risk stratification, preoperative optimization, and outcomes improvement.

Background: Hip fracture repair surgery carries a certain mortality risk, yet evidence suggests that orthopedic surgeons often refrain from discussing this issue with patients prior to surgery. Aim: This study aims to examine whether orthopedic surgeons raise the issue of one-year post-surgery mortality before hip fracture repair surgery and to explore factors influencing this decision. Method: The study employs a cross-sectional design, administering validated digital questionnaires to 150 orthopedic surgeons. Results: A minority of orthopedic surgeons reported always informing patients about the risk of mortality in the year following hip fracture surgery. The main reasons for not discussing this risk were a desire to avoid frightening patients, time constraints, and concerns about undermining patient hope. Orthopedic surgeons reported a medium-high level of perceived self-efficacy, with higher self-efficacy associated with a reduced likelihood of discussing one-year mortality risk. Conversely, older age and holding a specialist status in orthopedic surgery were associated with an increased likelihood of discussing this risk with patients. Conclusions: These findings suggest a need for interventions to address communication barriers and ensure consistent provision of essential information to patients undergoing hip fracture surgery. Additionally, they highlight the importance of considering individual factors such as self-efficacy, age, and expertise in designing strategies to improve patient-provider communication in orthopedic care settings. Trial registration: : The study doesn't report the results of a health care intervention. [ABSTRACT FROM AUTHOR]
