Background: Total elbow arthroplasty is an effective treatment for patients with painful elbow arthritis. Infection can be a serious complication. The aim of this scoping review was to document the available evidence on periprosthetic elbow infection. Methods: A search of Medline, Embase and PubMed was performed; two authors screened results independently. Systematic reviews, randomised controlled trials, cohort studies, case–control studies and case series including periprosthetic elbow infection were eligible. Results: A total of 46 studies were included. The median rate of periprosthetic elbow infection reported from recent published studies is 3.3%. The most commonly identified causative organisms are Staphylococcus aureus and Staphylococcus epidermidis. Risk factors include younger age, rheumatoid arthritis, obesity, previous surgery or infection to the elbow, and postoperative wound complications. Debridement, antibiotics and implant retention results in implant survival rates of 50–90%. Two-stage revision results in improved functional outcome scores, but with recurrent infection rates of 12–28%. Conclusions: Total elbow arthroplasty carries a higher risk of infection when compared to other major joint replacements. The current body of literature is limited and is almost exclusively low volume retrospective case series. The best management of periprosthetic elbow infection is difficult to determine, but two-stage revision appears to be the gold standard. [ABSTRACT FROM AUTHOR]

Background: The reported survivorship of total shoulder replacement (TSR) is variable. This is probably related to implant design. We report the outcome and survivorship of the uncemented glenoid in patients with osteoarthritis receiving a TSR with an intact or repairable rotator cuff at surgery. Methods: Thirty-two consecutive patients were analysed after TSR using a screw-fixed porous coated metal-back glenoid performed by a single surgeon, with a minimum follow-up of five years. Thirty-three TSRs in 32 patients (19 women) with a mean age of 67 years were analysed, two of whom died before five years of follow-up. Thirty patients (31 shoulders) were monitored for a mean of 95 months (60-173 months). Results: The Constant score improved by 22 points (p < 0.001). The only significant predictor of outcome on logistic regression analysis was the preoperative Constant score, with better scores resulting in a lesser improvement at last follow-up (p < 0.0001). Implant survivorship at ten years was 93 %. Three were revisions: two for polyethylene wear (both at six years) but with a well-fixed glenoid, and another for loosening of the glenoid at 11 years postoperatively. Univariate analysis identified that younger age (56 year vs. 68 years, p = 0.03) and a higher combined preoperative Constant score (35.7 vs. 21.5, p = 0.03) were both predictors of failure. Conclusion: The uncemented glenoid performs well in the medium term for osteoarthritis of the shoulder in older patients, giving improved and sustained functional outcome. Age and preoperative level of function are predictors of outcome and survival. [ABSTRACT FROM AUTHOR]

The use of arthroscopy of the hand and wrist has recently increased sharply in the elective setting and this, not surprisingly, has been followed by an increasing use in the trauma setting. Advocates for the use of arthroscopy in these patients cite the improved assessment of the displacement and reduction of fractures and the early diagnosis of associated injuries, while others temper this with concerns about increased operating time and possible complications. The data relating to patient-reported benefits and costs are limited. The aim of this review was to discuss the current available literature for the use of arthroscopy in the management of injuries of the hand and wrist., Competing Interests: A. D.

Background: There is a paucity of longer-term outcome data in younger adult patients who undergo fixation for an intracapsular hip fracture. The aims of this study were to evaluate the outcomes for young adult patients undergoing intracapsular hip fracture fixation and to assess factors associated with failure and patient-reported outcome measures (PROMs)., Methods: From 2008 to 2018, 112 consecutive patients ≤60 years of age (mean age, 48 years [range, 20 to 60 years]; 54% male) were retrospectively identified as having undergone fixation of an intracapsular hip fracture. Displaced fractures (n = 81) were more common than nondisplaced or minimally displaced fractures (n = 31). Failure was defined as loss of fixation, nonunion, or osteonecrosis. PROMs that were assessed included the Oxford Hip Score (OHS), Forgotten Joint Score (FJS), EuroQol 5-Dimension (EQ-5D) index and Visual Analogue Scale (EQ-VAS), and University of California Los Angeles (UCLA) Activity Scale., Results: Eighty-six patients (77%) had union without evidence of failure, and 26 patients (23%) had a failure, including loss of fixation (6 patients; 5.4%), nonunion (5 patients; 4.5%), and osteonecrosis (16 patients; 14.3%). Overall, 39 patients (35%) required secondary surgery, with hardware removal (21 patients; 18.8%) and total hip arthroplasty (21 patients; 18.8%) being the most frequent procedures. Long-term functional outcomes were obtained for 81 patients (72%) at a mean of 7 years (range, 2.8 to 12.8 years). The median OHS was 47 (interquartile range [IQR], 40-48), the median FJS was 75 (IQR, 49-85), the median EQ-5D index was 1.00 (IQR, 0.77-1.00), and the median EQ-VAS was 90 (IQR, 70-95). The mean UCLA score fell from 6.8 preinjury to 6.0 postinjury (p < 0.001). Compared with the patients who had primary union, those who had a complication had significantly lower median OHS scores (44.5 versus 47, p = 0.008), EQ-5D index scores (0.825 versus 1.00, p = 0.001), EQ-VAS scores (70 versus 90, p = 0.01), and UCLA scores (4.5 versus 6.5, p = 0.001)., Conclusions: One in 4 young adult patients undergoing intracapsular hip fracture fixation had a failure. Failure was associated with inferior long-term function and health-related quality of life., Level of Evidence: Therapeutic Level III.

Background: Hip fracture is common in older people and has significant health and care implications. This study aimed to examine the impact of household characteristics (living alone or living with someone who is themselves ill) on adverse outcomes following hip fracture., Methods: A cohort study of hip fracture patients aged ≥ 50 years living alone or with one co-resident using Welsh nationwide data between January 2013 and December 2018. Outcomes were emergency hospital admission within 30 days and care-home admission and mortality within one year of hospital discharge. Analysis used cause-specific Cox proportional hazards models to examine associations with living alone and with co-resident chronic disease status., Results: Of the 12,089 hip fracture patients discharged, 56.0% lived alone. Compared to hip fracture patients living with a co-resident, those living alone were more commonly women (78.4% versus 65.2%), older (mean 83.1 versus 78.5 years), and had more long-term conditions (mean 5.7 versus 5.3). In unadjusted analyses, compared to living with a co-resident with 0-1 long-term condition and no dementia, living alone (hazard ratio [HR] 1.44, 95%CI 1.23-1.68), living with someone with dementia (HR 1.57, 95%CI 1.07-2.30), and living with someone with 4 + physical long-term conditions (HR 1.24, 95%CI 1.03-1.49) were associated with an increase in mortality, but no significant association was found in adjusted analysis. Adjusted for age, sex, socioeconomic position, and long-term condition count of the hip fracture patient, living alone (adjusted HR [aHR] 2.26, 95%CI 1.81-2.81) and living with a co-resident with dementia (aHR 2.38, 95%CI 1.59-3.57) were both associated with more than double the risk of care home admission. There were no significant associations with 30-day hospital admission., Conclusions: Hip fracture patients who live alone have higher one-year mortality, but associations are explained by the demographic and clinical characteristics of those living alone. However, living alone or living with a co-resident with dementia was independently associated with an additional doubling of the risk of care home admission. Household-based approaches to research and health policy may help target risk groups following hip fracture community discharge and further research is needed to understand the mechanisms by which these associations act., Competing Interests: Declarations.

Background: The aims of this study were to assess whether delayed admission from the ED influenced mortality risk, length of acute hospital stay, risk of developing delirium and return to domicile for patients presenting with a hip fracture., Methods: A single centre service evaluation was undertaken including patients aged over 50 years who were admitted to a Scottish hospital through the ED with a hip fracture during a 42-month period (from January 2019 to June 2022). Delay was defined as spending >4 hours in the ED from arrival. Patient demographics and perioperative variables and mortality were collected. Cox regression analysis (adjusting for age, sex, season, socioeconomic status, American Society of Anesthesiologists grade, place of residence, fracture type, delirium and time from ward to theatre) was used to determine the independent association between delayed disposition from the ED and mortality (90 days and final follow-up) as recorded on a regional database., Results: The cohort consisted of 3266 patients with a mean age of 81 years, of which 2359 (72.2%) were female. 1261 (38.6%) patients stayed >4 hours in ED. The median follow-up was 529 days, during which time there were 1314 (40.2%) deaths. Survival at 90 days was significantly lower (hazard ratio [HR] 0.76, 95% CI 0.63 to 0.91) for patients who stayed >4 hours (92.9%) compared with those who stayed ≤4 hours (95.7%). Delayed disposition was independently associated with an increased mortality risk at 90 days (adjusted HR 1.36, 95% CI 1.12 to 1.63, p=0.001) and at final follow-up (adjusted HR 1.15, 95% CI 1.03 to 1.29, p=0.017). Delay was also associated with a longer length of hospital stay (difference in medians of 1 day, p<0.001). There were no differences in the risk of delirium on the ward (p=0.256) or return to place of residence (p≥0.315)., Conclusion: Delayed disposition from our ED was associated with an increased mortality risk and longer length of hospital stay in patients presenting with a hip fracture., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Aims: The primary aim of this study is to quantify and compare outcomes following a dorsally displaced fracture of the distal radius in elderly patients (aged ≥ 65 years) who are managed conservatively versus with surgical fixation (open reduction and internal fixation). Secondary aims are to assess and compare upper limb-specific function, health-related quality of life, wrist pain, complications, grip strength, range of motion, radiological parameters, healthcare resource use, and cost-effectiveness between the groups., Methods: A prospectively registered (ISRCTN95922938) randomized parallel group trial will be conducted. Elderly patients meeting the inclusion criteria with a dorsally displaced distal radius facture will be randomized (1:1 ratio) to either conservative management (cast without further manipulation) or surgery. Patients will be assessed at six, 12, 26 weeks, and 52 weeks post intervention. The primary outcome measure and endpoint will be the Patient-Rated Wrist Evaluation (PRWE) at 52 weeks. In addition, the abbreviated version of the Disabilities of Arm, Shoulder and Hand questionnaire (QuickDASH), EuroQol five-dimension questionnaire, pain score (visual analogue scale 1 to 10), complications, grip strength (dynamometer), range of motion (goniometer), and radiological assessments will be undertaken. A cost-utility analysis will be performed to assess the cost-effectiveness of surgery. We aim to recruit 89 subjects per arm (total sample size 178)., Discussion: The results of this study will help guide treatment of dorsally displaced distal radial fractures in the elderly and assess whether surgery offers functional benefit to patients. This is an important finding, as the number of elderly distal radial fractures is estimated to increase in the future due to the ageing population. Evidence-based management strategies are therefore required to ensure the best outcome for the patient and to optimize the use of increasingly scarce healthcare resources., Competing Interests: N. D.

Patients who sustain a contralateral hip fracture experience significantly inferior outcomes; however, the incidence and predictors of contralateral hip fracture remain poorly understood. In the present study, 2.5% of patients sustained a contralateral hip fracture within 12 months, and socioeconomic deprivation was associated with reduced risk of contralateral hip fracture., Introduction: Hip fractures are associated with high morbidity and mortality, and patients that sustain a subsequent contralateral fracture experience inferior outcomes. The risk of contralateral fracture is highest within the first year; however, the incidence and associated factors remain poorly understood. The aims were to investigate (i) the incidence of a subsequent contralateral hip fracture within the first year, (ii) identify factors associated with an increased risk of contralateral fracture and (iii) compare early mortality risk after index versus contralateral hip fracture., Methods: This study included all patients aged over 50 years admitted to NHS hospitals in Scotland between 1st March 2020 and 31st December 2020 (n = 5566) as routine activity of the Scottish Hip Fracture Audit (SHFA). Multivariate logistic regression was used to examine factors associated with 30-day mortality, and cox regression was used to identify factors associated with a contralateral fracture., Results: During the study period 2.5% (138/5566) of patients sustained a contralateral hip fracture within 12 months of the index hip fracture. Socioeconomic deprivation was inversely associated with increased risk of contralateral fracture (odds ratio 2.64, p < 0.001), whilst advancing age (p = 0.427) and sex (p = 0.265) were not. After adjusting for significant cofounders, there was no significant difference in 30-day mortality following contralateral fracture compared to index fracture (OR 1.22, p = 0.433)., Conclusion: One in 40 (2.5%) hip fracture patients sustained a contralateral fracture within 12 months of their index fracture, and deprivation was associated with a reduced risk of contralateral fracture. No difference in 30-day mortality was found., (© 2024. International Osteoporosis Foundation and Bone Health and Osteoporosis Foundation.)

Background: Multiple short delirium detection tools have been validated in research studies and implemented in routine care, but there has been little study of these tools in real-world conditions. This systematic review synthesized literature reporting completion rates and/or delirium positive score rates of detection tools in large clinical populations in general hospital settings., Methods: PROSPERO (CRD42022385166). Medline, Embase, PsycINFO, CINAHL, and gray literature were searched from 1980 to December 31, 2022. Included studies or audit reports used a validated delirium detection tool performed directly with the patient as part of routine care in large clinical populations (n ≥ 1000) within a general acute hospital setting. Narrative synthesis was performed., Results: Twenty-two research studies and four audit reports were included. Tools used alone or in combination were the Confusion Assessment Method (CAM), 4 'A's Test (4AT), Delirium Observation Screening Scale (DOSS), Brief CAM (bCAM), Nursing Delirium Screening Scale (NuDESC), and Intensive Care Delirium Screening Checklist (ICDSC). Populations and settings varied and tools were used at different stages and frequencies in the patient journey, including on admission only; inpatient, daily or more frequently; on admission and as inpatient; inpatient post-operatively. Tool completion rates ranged from 19% to 100%. Admission positive score rates ranged from: CAM 8%-51%; 4AT 13%-20%. Inpatient positive score rates ranged from: CAM 2%-20%, DOSS 6%-42%, and NuDESC 5-13%. Postoperative positive score rates were 21% and 28% (4AT). All but two studies had moderate-high risk of bias., Conclusions: This systematic review of delirium detection tool implementation in large acute patient populations found clinically important variability in tool completion rates, and in delirium positive score rates relative to expected delirium prevalence. This study highlights a need for greater reporting and analysis of relevant healthcare systems data. This is vital to advance understanding of effective delirium detection in routine care., (© 2024 The Authors.

Aims: The underlying natural history of suspected scaphoid fractures (SSFs) is unclear and assumed poor. There is an urgent requirement to develop the literature around SSFs to quantify the actual prevalence of intervention following SSF. Defining the risk of intervention following SSF may influence the need for widespread surveillance and screening of SSF injuries, and could influence medicolegal actions around missed scaphoid fractures., Methods: Data on SSF were retrospectively gathered from virtual fracture clinics (VFCs) across a large Scottish Health Board over a four-year period, from 1 January 2018 to 31 December 2021. The Bluespier Electronic Patient Record System identified any surgical procedure being undertaken in relation to a scaphoid injury over the same time period. Isolating patients who underwent surgical intervention for SSF was performed by cross-referencing the unique patient Community Health Index number for patients who underwent these scaphoid procedures with those seen at VFCs for SSF over this four-year period., Results: In total, 1,739 patients were identified as having had a SSF. Five patients (0.28%) underwent early open reduction and internal fixation (ORIF). One patient (0.06%) developed a nonunion and underwent ORIF with bone grafting. All six patients undergoing surgery were male (p = 0.005). The overall rate of intervention following a SSF was 0.35%. The early intervention rate in those undergoing primary MRI was one (0.36%), compared with three in those without (0.27%) (p > 0.576)., Conclusion: Surgical intervention was rare following a SSF and was not required in females. A primary MRI policy did not appear to be associated with any change in primary or secondary intervention. These data are the first and largest in recent literature to quantify the prevalence of surgical intervention following a SSF, and may be used to guide surveillance and screening pathways as well as define medicolegal risk involved in missing a true fracture in SSFs., Competing Interests: P.

Background: Virtual fracture clinics (VFCs) are advocated by the British Orthopaedic Association Standards for Trauma (BOAST). We aimed to assess the impact of the transition from face-to-face fracture clinic review and identify any change in clinical outcome and patient satisfaction., Methods: A national, cross-sectional cohort study of VFCs across the UK over two separate two-week periods pre- and during the first UK COVID-19 lockdown was undertaken. Data comprising patient and injury characteristics, unplanned reattendance and complications within three months following discharge from VFC were collected by local collaborators. Telephone questionnaires were conducted to determine patient satisfaction and patient-reported outcome for patients discharged without face-to-face consultation. The primary outcome measure was the percentage of unplanned reattendances after direct discharge from VFC., Results: Data was analysed for 51 UK VFCs comprising 6134 patients from the pre-pandemic group (06/05/2019-19/05/2019) and 4366 patients from the first UK lockdown (04/05/2020-17/05/2020). During lockdown, the rate of direct discharge from VFC increased significantly (odds ratio (OR) 2.01, p<0.001) from 30 % (n = 1856/6134) to 46 % (n = 2021/4366). The rate of compliance with BOAST guidance recommending fracture clinic review within three days increased (OR 1.93, p<0.001) from 82 % (n = 5003/6134) to 89 % (n = 3883/4366). There were no differences in the rates of unplanned reattendance (6 % pre- and 7 % during lockdown, p = 0.281) or complications (0.2 % for both, p = 0.815). There were 1527/3877 patients discharged without face-to-face review from VFC who completed telephone questionnaires (mean follow-up 18-months in pre-pandemic group and 6-months in lockdown group). Satisfaction was high in both cohorts (80 % pre- and 76 % lockdown, p = 0.093). Dissatisfaction was associated with an unplanned reattendance (p<0.001) or a missed injury (p<0.05)., Conclusion: Despite a significant rise in direct discharge from VFC, there was no significant change in unplanned attendances, complications, or patient satisfaction. However, there are factors associated with dissatisfaction and these should be considered in the evolution of VFC., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Aims: This study aimed to determine whether lateral femoral wall thickness (LWT) < 20.5 mm was associated with increased revision risk of intertrochanteric fracture (ITF) of the hip following sliding hip screw (SHS) fixation when the medial calcar was intact. Additionally, the study assessed the association between LWT and patient mortality., Methods: This retrospective study included ITF patients aged 50 years and over treated with SHS fixation between 2019 and 2021 at a major trauma centre. Demographic information, fracture type, delirium status, American Society of Anesthesiologists grade, and length of stay were collected. LWT and tip apex distance were measured. Revision surgery and mortality were recorded at a mean follow-up of 19.5 months (1.6 to 48). Cox regression was performed to evaluate independent risk factors associated with revision surgery and mortality., Results: The cohort consisted of 890 patients with a mean age of 82 years (SD 10.2). Mean LWT was 27.0 mm (SD 8.6), and there were 213 patients (23.9%) with LWT < 20.5 mm. Overall, 20 patients (2.2%) underwent a revision surgery following SHS fixation. Adjusting for covariates, LWT < 20.5 mm was not independently associated with an increased revision or mortality risk. However, factors that were significantly more prevalent in LWT < 20.5 mm group, which included residence in care home (hazard ratio (HR) 1.84; p < 0.001) or hospital (HR 1.65; p = 0.005), and delirium (HR 1.32; p = 0.026), were independently associated with an increased mortality risk. The only independent factor associated with increased risk of revision was older age (HR 1.07; p = 0.030)., Conclusion: LWT was not associated with risk of revision surgery in patients with an ITF fixed with a SHS when the calcar was intact, after adjusting for the independent effect of age. Although LWT < 20.5 mm was not an independent risk factor for mortality, patients with LWT < 20.5 mm were more likely to be from care home or hospital and have delirium on admission, which were associated with a higher mortality rate., Competing Interests: The following authors have disclosures, all of which were unrelated to this work: B.

CTLA-4 is a crucial immune checkpoint receptor involved in the maintenance of immune homeostasis, tolerance, and tumor control. Antibodies targeting CTLA-4 have been promising treatments for numerous cancers, but the mechanistic basis of their anti-tumoral immune-boosting effects is poorly understood. Although the ctla4 gene also encodes an alternatively spliced soluble variant (sCTLA-4), preclinical/clinical evaluation of anti-CTLA-4-based immunotherapies have not considered the contribution of this isoform. Here, we explore the functional properties of sCTLA-4 and evaluate the efficacy of isoform-specific anti-sCTLA-4 antibody targeting in a murine cancer model. We show that expression of sCTLA-4 by tumor cells suppresses CD8 + T cells in vitro and accelerates growth and experimental metastasis of murine tumors in vivo. These effects were accompanied by modification of the immune infiltrate, notably restraining CD8 + T cells in a non-cytotoxic state. sCTLA-4 blockade with isoform-specific antibody reversed this restraint, enhancing intratumoral CD8 + T cell activation and cytolytic potential, correlating with therapeutic efficacy and tumor control. This previously unappreciated role of sCTLA-4 suggests that the biology and function of multi-gene products of immune checkpoint receptors need to be fully elucidated for improved mechanistic understanding of cancer immunotherapies., Competing Interests: Declaration of interests F.J.W. and L.N.D. are inventors on a patent (US8697845 B2) covering the use of the anti-sCTLA-4 monoclonal antibody as a therapeutic., (Copyright © 2023 The Author(s).

This nationwide study used data-linked records to assess the effect of COVID-19 vaccination among hip fracture patients. Vaccination was associated with a lower risk of contracting COVID-19 and, among COVID-positive patients, it reduced the mortality risk to that of COVID-negative patients. This provides essential data for future communicable disease outbreaks., Purpose: COVID-19 confers a three-fold increased mortality risk among hip fracture patients. The aims were to investigate whether vaccination was associated with: i) lower mortality risk, and ii) lower likelihood of contracting COVID-19 within 30 days of fracture., Methods: This nationwide cohort study included all patients aged > 50 years that sustained a hip fracture in Scotland between 01/03/20-31/12/21. Data from the Scottish Hip Fracture Audit were collected and included: demographics, injury and management variables, discharge destination, and 30-day mortality status. These variables were linked to government-managed population level records of COVID-19 vaccination and laboratory testing., Results: There were 13,345 patients with a median age of 82.0 years (IQR 74.0-88.0), and 9329/13345 (69.9%) were female. Of 3022/13345 (22.6%) patients diagnosed with COVID-19, 606/13345 (4.5%) were COVID-positive within 30 days of fracture. Multivariable logistic regression demonstrated that vaccinated patients were less likely to be COVID-positive (odds ratio (OR) 0.41, 95% confidence interval (CI) 0.34-0.48, p < 0.001) than unvaccinated patients. 30-day mortality rate was higher for COVID-positive than COVID-negative patients (15.8% vs 7.9%, p < 0.001). Controlling for confounders (age, sex, comorbidity, deprivation, pre-fracture residence), unvaccinated patients with COVID-19 had a greater mortality risk than COVID-negative patients (OR 2.77, CI 2.12-3.62, p < 0.001), but vaccinated COVID19-positive patients were not at increased risk of death (OR 0.93, CI 0.53-1.60, p = 0.783)., Conclusion: Vaccination was associated with lower COVID-19 infection risk. Vaccinated COVID-positive patients had a similar mortality risk to COVID-negative patients, suggesting a reduced severity of infection. This study demonstrates the efficacy of vaccination in this vulnerable patient group, and presents data that will be valid in the management of future outbreaks., (© 2023.

Purpose: To determine the feasibility and reliability of ultrasound in the assessment of humeral shaft fracture healing and estimate the accuracy of 6wk ultrasound in predicting nonunion., Methods: Twelve adults with a non-operatively managed humeral shaft fracture were prospectively recruited and underwent ultrasound scanning at 6wks and 12wks post-injury. Seven blinded observers evaluated sonographic callus appearance to determine intra- and inter-observer reliability. Nonunion prediction accuracy was estimated by comparing images for patients that united (n = 10/12) with those that developed a nonunion (n = 2/12)., Results: The mean scan duration was 8 min (5-12) and all patients tolerated the procedure. At 6wks and 12wks, sonographic callus (SC) was present in 11 patients (10 united, one nonunion) and sonographic bridging callus (SBC) in seven (all united). Ultrasound had substantial intra- (weighted kappa: 6wk 0.75; 12wk 0.75) and inter-observer reliability (intraclass correlation coefficient: 6wk 0.60; 12wk 0.76). At 6wks, the absence of SC demonstrated sensitivity 50%, specificity 100%, positive predictive value (PPV) 100% and negative predictive value (NPV) 91% in nonunion prediction (overall accuracy 92%). The absence of SBC demonstrated sensitivity 100%, specificity 70%, PPV 40% and NPV 100% in nonunion prediction (overall accuracy 75%). Of three patients at risk of nonunion (Radiographic Union Score for HUmeral fractures < 8), one had SBC on 6wk ultrasound (that subsequently united) and the others had non-bridging/absent SC (both developed nonunion)., Conclusions: Ultrasound assessment of humeral shaft fracture healing was feasible, reliable and may predict nonunion. Ultrasound could be useful in defining nonunion risk among patients with reduced radiographic callus formation., (© 2023. The Author(s).)

Importance: Unstable ankle fractures are routinely managed operatively. However, because of soft tissue and implant-related complications, recent literature has reported on the nonoperative management of well-reduced medial malleolus fractures after fibular stabilization, but with limited evidence supporting the routine application., Objective: To assess the superiority of internal fixation of well-reduced (displacement ≤2 mm) medial malleolus fractures compared with nonfixation after fibular stabilization., Design, Setting, and Participants: This superiority, pragmatic, parallel, prospective randomized clinical trial was conducted from October 1, 2017, to August 31, 2021. A total of 154 adult participants (≥16 years) with a closed, unstable bimalleolar or trimalleolar ankle fracture requiring surgery at an academic major trauma center in the UK were assessed. Exclusion criteria included injuries with no medial-sided fracture, open fractures, neurovascular injury, and the inability to comply with follow-up. Data analysis was performed in July 2022 and confirmed in September 2023., Interventions: Once the lateral (and where appropriate, posterior) malleolus had been fixed and satisfactory intraoperative reduction of the medial malleolus fracture was confirmed by the operating surgeon, participants were randomly allocated to fixation (n = 78) or nonfixation (n = 76) of the medial malleolus., Main Outcome and Measure: Olerud-Molander Ankle Score (OMAS) 1 year after randomization (range, 0-100 points, with 0 indicating worst possible outcome and 100 indicating best possible outcome)., Results: Among 154 randomized participants (mean [SD] age, 56.5 [16.7] years; 119 [77%] female), 144 (94%) completed the trial. At 1 year, the median OMAS was 80.0 (IQR, 60.0-90.0) in the fixation group compared with 72.5 (IQR, 55.0-90.0) in the nonfixation group (P = .17). Complication rates were comparable. Significantly more patients in the nonfixation group developed a radiographic nonunion (20% vs 0%; P < .001), with 8 of 13 clinically asymptomatic; 1 patient required surgical reintervention for this. Fracture type and reduction quality appeared to influence fracture union and patient outcome., Conclusions and Relevance: In this randomized clinical trial comparing internal fixation of well-reduced medial malleolus fractures with nonfixation, after fibular stabilization, fixation was not superior according to the primary outcome. However, 1 in 5 patients developed a radiographic nonunion after nonfixation, and although the reintervention rate to manage this was low, the future implications are unknown. These results support selective nonfixation of anatomically reduced medial malleolar fractures after fibular stabilization., Trial Registration: ClinicalTrials.gov Identifier: NCT03362229.

In situ hybridization of oligonucleotide probes to intracellular RNA allows quantification of predefined gene transcripts within millions of single cells using cytometry platforms. Previous methods have been hindered by the number of RNA that can be analyzed simultaneously. Here we describe a method called proximity ligation assay for RNA (PLAYR) that permits highly multiplexed RNA analysis that can be combined with antibody staining. Potentially any number of RNA combined with antigen can be analyzed together, being limited only by the number of analytes that can be measured simultaneously., (© 2024.

Purpose: The primary aim of this study was to define the rate of infection following revision of fixation for aseptic failure. The secondary aims were to identify factors associated with an infection following revision and patient morbidity following deep infection., Methods: A retrospective study was undertaken to identify patients who underwent aseptic revision surgery during a 3-year period (2017-2019). Regression analysis was used to identify independent factors associated with SSI., Results: Eighty-six patients were identified that met the inclusion criteria, with a mean age of 53 (range 14-95) years and 48 (55.8%) were female. There were 15 (17%) patients with an SSI post revision surgery (n = 15/86). Ten percent (n = 9) of all revisions acquired a 'deep infection', which carried a high morbidity with a total of 23 operations, including initial revision, being undertaken for these patients as salvage procedures and three progressed to an amputation. Alcohol excess (odds ratio (OR) 1.61, 95% CI 1.01-6.36, p = 0.046) and chronic obstructive pulmonary disease (OR 11.1, 95% CI 1.00-133.3, p = 0.050) were independently associated with an increased risk of SSI., Conclusion: Aseptic revision surgery had a high rate of SSI (17%) and deep infection (10%). All deep infections occurred in the lower limb with the majority of these seen in ankle fractures. Alcohol excess and COPD were independent risk factors associated with an SSI and patients with a history of these should be counselled accordingly., Level of Evidence: Retrospective Case Series, Level IV., (© 2023.

Aims: Hip fractures are a major cause of morbidity and mortality, and malnutrition is a crucial determinant of these outcomes. This meta-analysis aims to determine whether oral nutritional supplementation (ONS) improves postoperative outcomes in older patients with a hip fracture., Methods: A systematic literature search was conducted in August 2022. ONS was defined as high protein-based diet strategies containing (or not containing) carbohydrates, fat, vitamins, and minerals. Randomized trials documenting ONS in older patients with hip fracture (aged ≥ 50 years) were included. Two reviewers evaluated study eligibility, conducted data extraction, and assessed study quality., Results: There were 812 studies identified, of which 18 studies involving 1,522 patients met the inclusion criteria. The overall meta-analysis demonstrated that ONS was associated with significantly elevated albumin levels (weighted mean difference (WMD) 1.24 (95% confidence interval (CI) 0.95 to 1.53)), as well as a significant risk reduction in infective complications (odds ratio (OR) 0.54 (95% CI 0.39 to 0.76)), pressure ulcers (OR 0.54 (95% CI 0.33 to 0.88)), and total complications (OR 0.57 (95% CI 0.42 to 0.79)). Length of hospital stay (LOS) was also significantly reduced (WMD -2.36 (95% CI -4.14 to -0.58)), particularly in rehabilitation LOS (WMD -4.17 (95% CI -7.08 to -1.26)). There was a tendency towards a lower mortality risk (OR 0.93 (95% CI 0.62 to 1.4)) and readmission (OR 0.52 (95% CI 0.16 to 1.73)), although statistical significance was not achieved (p = 0.741 and p = 0.285, respectively). The overall compliance with ONS ranged from 64.7% to 100%, but no factors influencing compliance were identified., Conclusion: This meta-analysis is the first to quantitatively demonstrate that ONS could nearly halve the risk of infective complications, pressure ulcers, total complications, as well as improve serum albumin and reduce LOS. ONS should be a regular and integrated part of the perioperative care of these patients, especially given that the compliance with ONS is acceptable., Competing Interests: B.

Objective: Acute compartment syndrome (ACS) is a true emergency. Even with urgent fasciotomy, there is often muscle damage and need for further surgery. Although ACS is not uncommon, no validated classification system exists to aid in efficient and clear communication. The aim of this study was to establish and validate a classification system for the consequences of ACS treated with fasciotomy., Methods: Using a modified Delphi method, an international panel of ACS experts was assembled to establish a grading scheme for the disease and then validate the classification system. The goal was to articulate discrete grades of ACS related to fasciotomy findings and associated costs. A pilot analysis was used to determine questions that were clear to the respondents. Discussion of this analysis resulted in another round of cases used for 24 other raters. The 24 individuals implemented the classification system 2 separate times to compare outcomes for 32 clinical cases. The accuracy and reproducibility of the classification system were subsequently calculated based on the providers' responses., Results: The Fleiss Kappa of all raters was at 0.711, showing a strong agreement between the 24 raters. Secondary validation was performed for paired 276 raters and correlation was tested using the Kendall coefficient. The median correlation coefficient was 0.855. All 276 pairs had statistically significant correlation. Correlation coefficient between the first and second rating sessions was strong with the median pair scoring at 0.867. All surgeons had statistically significant internal consistency., Conclusion: This new ACS classification system may be applied to better understand the impact of ACS on patient outcomes and economic costs for leg ACS., (Copyright © 2023 Wolters Kluwer Health, Inc.

Aims: To develop a reliable and effective radiological score to assess the healing of isolated ulnar shaft fractures (IUSF), the Radiographic Union Score for Ulna fractures (RUSU)., Methods: Initially, 20 patients with radiographs six weeks following a non-operatively managed ulnar shaft fracture were selected and scored by three blinded observers. After intraclass correlation (ICC) analysis, a second group of 54 patients with radiographs six weeks after injury (18 who developed a nonunion and 36 who united) were scored by the same observers., Results: In the initial study, interobserver and intraobserver ICC were 0.89 and 0.93, respectively. In the validation study, the interobserver ICC was 0.85. The median score for patients who united was significantly higher than those who developed a nonunion (11 vs. 7, p < 0.001). A ROC curve demonstrated that a RUSU ≤ 8 had a sensitivity of 88.9% and specificity of 86.1% in identifying patients at risk of nonunion. Patients with a RUSU ≤ 8 (n = 21) were more likely to develop a nonunion (n = 16/21) than those with a RUSU ≥ 9 (n = 2/33; OR 49.6, 95% CI 8.6-284.7). Based on a PPV of 76%, if all patients with a RUSU ≤ 8 underwent fixation at 6 weeks, the number of procedures needed to avoid one nonunion would be 1.3., Conclusion: The RUSU shows good interobserver and intraobserver reliability and is effective in identifying patients at risk of nonunion six weeks after fracture. This tool requires external validation but may enhance the management of patients with isolated ulnar shaft fractures., (© 2023.

Purpose: The primary aim was to evaluate the impact of COVID-19 on frailty in patients surviving a hip fracture. Secondary aims were to assess impact of COVID-19 on (i) length of stay (LoS) and post-discharge care needs, (ii) readmissions, and (iii) likelihood of returning to own home., Methods: This propensity score-matched case-control study was conducted in a single centre between 01/03/20-30/11/21. A 'COVID-positive' group of 68 patients was matched to 141 'COVID-negative' patients. 'Index' and 'current' Clinical Frailty Scale (CFS) scores were assigned for frailty at admission and at follow-up. Data were extracted from validated records and included: demographics, injury factors, COVID-19 status, delirium status, discharge destination, and readmissions. For subgroup analysis controlling for vaccination availability, the periods 1 March 2020-30 November 2020 and 1 February 2021-30 November 2021 were considered pre-/post-vaccine periods., Results: Median age was 83.0 years, 155/209 (74.2%) were female and median follow-up was 479 days (interquartile range [IQR] 311). There was an equivalent median increase in CFS in both groups (+1.00 [IQR 1.00-2.00, p = 0.472]). However, adjusted analysis demonstrated COVID-19 was independently associated with a greater magnitude change (Beta coefficient [β] 0.27, 95% confidence interval [95% CI] 0.00-0.54, p = 0.05). COVID-19 in the post-vaccine availability period was associated with a smaller increase versus pre-vaccine (β -0.64, 95% CI -1.20 to -0.09, p = 0.023). COVID-19 was independently associated with increased acute LoS (β 4.40, 95% CI 0.22-8.58, p = 0.039), total LoS (β 32.87, 95% CI 21.42-44.33, p < 0.001), readmissions (β 0.71, 95% CI 0.04-1.38, p = 0.039), and a four-fold increased likelihood of pre-fracture home-dwelling patients failing to return home (odds ratio 4.52, 95% CI 2.08-10.34, p < 0.001)., Conclusions: Hip fracture patients that survived a COVID-19 infection had increased frailty, longer LoS, more readmissions, and higher care needs. The health and social care burden is likely to be higher than prior to the COVID-19 pandemic. These findings should inform prognostication, discharge-planning, and service design to meet the needs of these patients., (© 2023 The Authors.

This study assessed the lead and trail arm peak and average extensor carpi ulnaris (ECU) muscle activity in association with tri-planar angular velocities of the lead and trail wrists during the golf swing. Fifteen sub-elite, male right-handed golfers ( M age  = 34.7 years ±13.3, M handicap  = 1.5 ± 2.2) were recruited to execute five shots each with their pitching wedge, 7-iron and driver clubs in an indoor golf simulator. Surface electromyography (EMG) sensors were placed over the ECU muscle belly and inertial measurement unit sensors were placed bi-laterally on the distal forearm and dorsum of the hand. There was a statistically greater recruitment of the trail ECU muscle during the downswing ( p  < 0.001) for all clubs. The lead ECU muscle was recruited more during the backswing ( p  < 0.001) and follow through ( p  < 0.024) phases. There were statistically different tri-planar movement patterns between the lead and trail wrist throughout all three phases of the golf swing. No significant relationships were found between downswing EMG data and clubhead kinematics at impact. In conclusion, differing wrist kinematics and associated muscle activity may contribute to the asymmetrical injury pattern seen clinically.

The aims of this study were to assess whether completion of the emergency department (ED) Big 6 interventions (provision of pain relief, screening for delirium, early warning score (EWS) system, full blood investigation and electrocardiogram, intravenous fluids therapy, and pressure area care) in those presenting with an acute hip fracture were associated with mortality risk and length of acute hospital stay. A retrospective cohort study was undertaken. All patients aged ≥50 years that were admitted with a hip fracture via the ED at a single centre during a 42-month period were included. A total of 3613 patients (mean age 80.9; 71% female) were included. The mean follow up was 607 (range 240 to 1542) days. A total of 1180 (32.7%) patients had all six components completed. Pain relief (90.8%) was the most frequently completed component and pressure area assessment (57.6%) was the least. Completion of each of the individual Big 6 components, except for pressure areas assessment, were associated with a significantly ( p ≤ 0.041) lower mortality risk at the 90-days, one-year and final follow-up. The completion of all components of the Big 6 was associated with a significantly (2.4 hours, p = 0.002) shorter time to theatre. Increasing number of Big 6 components completed were independently associated with a lower mortality risk: when all six were completed, the hazard ratio was 0.64 (95% CI 0.52 to 0.78, p < 0.001). Completion of an increasing number of Big 6 components was independently associated with shorter length of hospital stay and completion of all six was associated with a 2.3 (95% CI 0.9 to 3.8)-day shorter acute stay. The findings provide an evidence base to support the ongoing use of the Big 6 in the ED.

Background: The aim of this study was to determine the floor and ceiling effects for both the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire) and the PRWE (Patient-Rated Wrist Evaluation) following a distal radial fracture (DRF). Secondary aims were to determine the degree to which patients with a floor or ceiling effect felt that their wrist was "normal" according to the Normal Wrist Score (NWS) and if there were patient factors associated with achieving a floor or ceiling effect., Methods: A retrospective cohort study of patients in whom a DRF was managed at the study center during a single year was undertaken. Outcome measures included the QuickDASH, PRWE, EuroQol-5 Dimensions-3 Levels (EQ-5D-3L), and NWS., Results: There were 526 patients with a mean age of 65 years (range, 20 to 95 years), and 421 (80%) were female. Most patients were managed nonsurgically (73%, n = 385). The mean follow-up was 4.8 years (range, 4.3 to 5.5 years). A ceiling effect was observed for both the QuickDASH (22.3% of patients with the best possible score) and the PRWE (28.5%). When defined as a score that differed from the best available score by less than the minimum clinically important difference (MCID) for the scoring system, the ceiling effect increased to 62.8% for the QuickDASH and 60% for the PRWE. Patients who had a ceiling score on the QuickDASH and the PWRE had a median NWS of 96 and 98, respectively, and those who had a score within 1 MCID of the ceiling score reported a median NWS of 91 and 92, respectively. On logistic regression analysis, a dominant-hand injury and better health-related quality of life were the factors associated with both QuickDASH and PRWE ceiling scores (all p < 0.05)., Conclusions: The QuickDASH and PRWE demonstrate ceiling effects when used to assess the outcome of DRF management. Some patients achieving ceiling scores did not consider their wrist to be "normal." Future research on patient-reported outcome assessment tools for DRFs should aim to limit the ceiling effect, especially for individuals or groups that are more likely to achieve a ceiling score., Level of Evidence: Prognostic Level III .

Shoulder injury related to vaccine administration (SIRVA) is a prolonged episode of shoulder dysfunction that commences within 24 to 48 hours of a vaccination. Symptoms include a combination of shoulder pain, stiffness, and weakness. There has been a recent rapid increase in reported cases of SIRVA within the literature, particularly in adults, and is likely related to the mass vaccination programmes associated with COVID-19 and influenza. The pathophysiology is not certain, but placement of the vaccination in the subdeltoid bursa or other pericapsular tissue has been suggested to result in an inflammatory capsular process. It has been hypothesized that this is associated with a vaccine injection site that is "too high" and predisposes to the development of SIRVA. Nerve conduction studies are routinely normal, but further imaging can reveal deep-deltoid collections, rotator cuff tendinopathy and tears, or subacromial subdeltoid bursitis. However, all of these are common findings within a general asymptomatic population. Medicolegal claims in the UK, based on an incorrect injection site, are unlikely to meet the legal threshold to determine liability., Competing Interests: P. J.

Purpose: Positive ulnar variance following a distal radius malunion can lead to ulnar-sided wrist pain, loss of grip strength, and distal radioulnar joint impingement. The primary aim of this study is to describe upper limb-specific functional outcomes following ulnar shortening osteotomy (USO) for ulnar-sided wrist pain associated with malunion of the distal radius., Methods: We retrospectively identified 40 adult patients from a single centre over a 9-year period that had undergone an USO for symptomatic malunion of the distal radius. The primary outcome was the patient-rated wrist evaluation (PRWE). Secondary outcomes were the QuickDASH, EQ-5D-5L, complications, and net promoter score (NPS)., Results: Outcomes were available for 37 patients (93%). The mean age was 56 years and 25 patients were female (68%). At a mean follow-up of 6 years (range 1-10 years) the median PRWE was 11 (IQR 0-29.5), the median QuickDASH 6.8 (IQR 0-29.5), and the median EQ-5D-5L index was 0.88 (IQR 0.71-1). The NPS was 73. Complications occurred in nine patients (24%) and included non-union (n = 4), early loss of fixation requiring revision surgery (n = 1), superficial wound infection (n = 2), neurological injury (n = 1), and further surgery for symptomatic hardware removal (n = 1)., Conclusions: For patients with a symptomatic distal radius malunion where the predominant deformity is ulnar positive variance, this study has demonstrated that despite 1 in 4 patients experiencing a complication, USO can result in excellent patient reported outcomes with high levels of satisfaction., Level of Evidence: III (Cohort Study)., (© 2022.

Aims: Delirium is associated with adverse outcomes following hip fracture, but the prevalence and significance of delirium for the prognosis and ongoing rehabilitation needs of patients admitted from home is less well studied. Here, we analyzed relationships between delirium in patients admitted from home with 1) mortality; 2) total length of hospital stay; 3) need for post-acute inpatient rehabilitation; and 4) hospital readmission within 180 days., Methods: This observational study used routine clinical data in a consecutive sample of hip fracture patients aged ≥ 50 years admitted to a single large trauma centre during the COVID-19 pandemic between 1 March 2020 and 30 November 2021. Delirium was prospectively assessed as part of routine care by the 4 A's Test (4AT), with most assessments performed in the emergency department. Associations were determined using logistic regression adjusted for age, sex, Scottish Index of Multiple Deprivation quintile, COVID-19 infection within 30 days, and American Society of Anesthesiologists grade., Results: A total of 1,821 patients were admitted, with 1,383 (mean age 79.5 years; 72.1% female) directly from home. Overall, 87 patients (4.8%) were excluded due to missing 4AT scores. Delirium prevalence in the whole cohort was 26.5% (460/1,734): 14.1% (189/1,340) in the subgroup of patients admitted from home, and 68.8% (271/394) in the remaining patients (comprising care home residents and inpatients when fracture occurred). In patients admitted from home, delirium was associated with a 20-day longer total length of stay (p < 0.001). In multivariable analyses, delirium was associated with higher mortality at 180 days (odds ratio (OR) 1.69 (95% confidence interval (CI) 1.13 to 2.54); p = 0.013), requirement for post-acute inpatient rehabilitation (OR 2.80 (95% CI 1.97 to 3.96); p < 0.001), and readmission to hospital within 180 days (OR 1.79 (95% CI 1.02 to 3.15); p = 0.041)., Conclusion: Delirium affects one in seven patients with a hip fracture admitted directly from home, and is associated with adverse outcomes in these patients.

Introduction: Socioeconomic deprivation is associated with multi-morbidity and frailty, but influence on hip fracture outcomes is poorly understood. The primary aim was to investigate the association between deprivation and mortality, and secondary aims were to assess the effects on: (i) age at presentation; (ii) inpatient outcomes, and (iii) post-discharge outcomes., Method: This cohort study included all patients aged >50 years admitted with a hip fracture to a high-volume centre between 01 March 2020 and 20 November 2021. Data were collected contemporaneously by specialist auditors and underwent validation using live health records after 180 days follow-up. Variables were demographics including Scottish Index of Multiple Deprivation, injury and management factors, and outcome measures including length of stay, discharge destination, readmission, and mortality status at 180 days., Results: There were 1822 patients of which 1306/1822 (72%) were female. Deprivation was independently associated with younger age at hip fracture, demonstrating a linear correlation with each deprivation level. The overall mean age was 80.7 years (range 50-102), with the mean age in the most deprived group being 77.2 years (95% CI; 75.7-78.7) versus 82.8 years (95% CI; 82.0-83.5) in the least deprived. Multivariate logistic regression showed no association between deprivation and 30- or 180-day mortality risk. Kaplan-Meier survival analysis demonstrated no difference between the most deprived versus least deprived (log-rank, p = 0.854). Deprivation had no influence on length of stay, discharge destination, or COVID-19 status, but deprived patients had an increased risk of readmission (OR 1.63, 95% CI [1.18-2.24]; p = 0.003)., Conclusion: Deprivation showed no linear correlation with early mortality risk (within 180 days of injury), but it was associated with an earlier age at presentation (the most deprived sustained a hip fracture 5.6 years earlier than the least deprived) which may impact overall life expectancy. More deprived patients were more likely to require further acute hospital admissions., (© 2022 The Authors. Musculoskeletal Care published by John Wiley & Sons Ltd.)

Aims: This study aims to determine whether intraoperative intravenous (IV) tranexamic acid (TXA) affects blood loss following the surgical management of femoral fragility fractures (FFF)., Methods: This was a single centre (university teaching hospital) non-randomised case-control study. There were 361 consecutive patients with FFF admitted over a 4-month period were included (mean age 81.4yrs; mean BMI 23.5; 73.7% female). Patient demographics, comorbidities, preoperative anticoagulation use, surgical management, intravenous TXA use, perioperative haemoglobin (Hb) and haematocrit, and requirement for blood transfusion were recorded. The primary outcome was postoperative blood transfusion requirement. Secondary outcomes included postoperative day one calculated blood loss (CBL) (using the Nadler and Gross formulae) and fall in Hb (percentage) from preoperative levels; and the incidence of thrombotic events and mortality up to 30 days., Results: Groups were well matched in terms of patient demographics, comorbidities, preoperative anticoagulation use, injury types and surgical management. Intravenous TXA 1 g given at the beginning of surgery at the discretion of the operating team: 178 (49%) received TXA and 183 (51%) did not. The requirement for postoperative blood transfusion was significantly less in the TXA group: 15/178 (8.4%) compared to 58/183 (31.7%) (p < 0.001; Chi square). TXA significantly reduced both the percentage fall in Hb (mean difference 4.3%, p < 0.001) and the CBL (mean difference -222 ml, p < 0.001). There was no difference in VTE (2 vs 1, p = 0.620) or other thrombotic events (2 vs 0, p = 0.244) between groups., Conclusion: 1 g of intraoperative intravenous TXA during the surgical management of FFF was associated with reduced rate of transfusion, CBL and the percentage drop in HB. The use of TXA in this study was not randomised, so there could be un-quantifiable bias in the patient selection., (© 2023. The Author(s).)

Objectives: To delineate whether a "safe" window exists for timing from definitive fixation to definitive soft tissue coverage in the treatment of open tibial diaphyseal fractures requiring flap coverage., Design: International multicenter, retrospective comparative cohort study., Patients/participants: Three hundred and seventy-three (n = 373) patients who sustained an open tibial shaft fracture requiring flap coverage., Methods: We evaluated the deep infection rates based on the timing between the definitive fixation and flap coverage. We determined several intervals of time from the day of definitive fixation (regardless of time from injury) and flap coverage. If performed on the same operative setting these were considered day 0. We evaluated coverage after 2 and 5 days from definitive fixation based on time versus infection rate curve inflection points. We adjusted for time to debridement and antibiotics within an hour., Main Outcome Measurement: Deep infection after definitive fixation and flap coverage., Results: The mean age of the cohort was 42.4 years (SD = 18.2) and 270 were male (72.4%). The deep infection rate after flap coverage was 20.6% (77/373). Definitive fixation to flap coverage time of up to 2 days was not associated with an increased risk of infection [relative risk (RR) = 1.12; 95% confidence interval, 0.92-1.37; P = 0.26]. There was an increased risk of deep infection for more than 2 days (RR = 1.59) and >5 days (RR = 1.64)., Conclusion: This study observed a "safe" window of up to 2 days between definitive fixation and flap coverage in open tibial shaft fractures requiring coverage before a statistical increase in risk of deep infection rate occurred., Level of Evidence: Therapeutic Level III.
