Aims. This is a multicentre, prospective assessment of a proportion of the overall orthopaedic trauma caseload of the UK. It investigates theatre capacity, cancellations, and time to surgery in a group of hospitals that is representative of the wider population. It identifies barriers to effective practice and will inform system improvements. Methods. Data capture was by collaborative approach. Patients undergoing procedures from 22 August 2022 and operated on before 31 October 2022 were included. Arm one captured weekly caseload and theatre capacity. Arm two concerned patient and injury demographics, and time to surgery for specific injury groups. Results. Data was available from 90 hospitals across 86 data access groups (70 in England, two in Wales, ten in Scotland, and four in Northern Ireland). After exclusions, 709 weeks' of data on theatre capacity and 23,138 operations were analyzed. The average number of cases per operating session was 1.73. Only 5.8% of all theatre sessions were dedicated day surgery sessions, despite 29% of general trauma patients being eligible for such pathways. In addition, 12.3% of patients experienced at least one cancellation. Delays to surgery were longest in Northern Ireland and shortest in England and Scotland. There was marked variance across all fracture types. Open fractures and fragility hip fractures, influenced by guidelines and performance renumeration, had short waits, and varied least. In all, nine hospitals had 40 or more patients waiting for surgery every week, while seven had less than five. Conclusion. There is great variability in operative demand and list provision seen in this study of 90 UK hospitals. There is marked variation in nearly all injuries apart from those associated with performance monitoring. There is no evidence of local network level coordination of care for orthopaedic trauma patients. Day case operating and pathways of care are underused and are an important area for service improvement. Cite this article: Bone Jt Open 2023;4(6):463–471

Aims. This study aimed to describe practice variation in the use of total hip arthroplasty (THA) for older patients with femoral neck fracture and to determine the association between patient, surgeon, and institution factors and treatment with THA. Methods. We performed a cross-sectional analysis of 49,597 patients aged 60 years and older from Ontario, Canada, who underwent hemiarthroplasty or THA for femoral neck fracture between 2002 and 2017. This population-based study used routinely collected healthcare databases linked through ICES (formerly known as the Institute for Clinical Evaluative Sciences). Multilevel logistic regression modelling was used to quantify the association between patient, surgeon, and institution-level variables and whether patients were treated with THA. Variance partition coefficient and median odds ratios were used to estimate the variation attributable to higher-level variables and the magnitude of effect of higher-level variables, respectively. Results. Over the study period, 9.4% of patients (n = 4,638) were treated with THA. Patient factors associated with higher likelihood of treatment by THA included: younger age, male sex, and diagnosis with rheumatoid arthritis. Long-term care residence, use of home care services prior to hip fracture, diagnosis of dementia, higher comorbidity burden, and the most marginalized group were negatively associated with treatment by THA. Treating surgeon and institution accounted for 54.2% and 17.8% of the total variation in treatment with THA, respectively. Surgeon volume of THA procedures in the 365 days prior to surgery was the strongest higher-level predictor of treatment with THA. Specific treating surgeons and institutions still accounted for significant proportions of the variability in treatment with THA (40.3% and 19.5% of total observed variation, respectively) after controlling for available patient, surgeon, and institution-level variables. Conclusion. The strongest predictors for treatment of patients with femoral neck fracture with THA were patient age, treating surgeon, and treating institution. This practice variation highlights differential access to care for patients. Cite this article: Bone Joint J 2023;105-B(2):180–189

Aims. Patients with A1 and A2 trochanteric hip fractures represent a substantial proportion of trauma caseload, and national guidelines recommend that sliding hip screws (SHS) should be used for these injuries. Despite this, intramedullary nails (IMNs) are routinely implanted in many hospitals, at extra cost and with unproven patient outcome benefit. We have used data from the National Hip Fracture Database (NHFD) to examine the use of SHS and IMN for A1 and A2 hip fractures at a national level, and to define the cost implications of management decisions that run counter to national guidelines. Methods. We used the NHFD to identify all operations for fixation of trochanteric fractures in England and Wales between 1 January 2021 and 31 December 2021. A uniform price band from each of three hip fracture implant manufacturers was used to set cost implications alongside variation in implant use. Results. We identified 18,156 A1 and A2 trochanteric hip fractures in 162 centres. Of these, 13,483 (74.3%) underwent SHS fixation, 2,352 (13.0%) were managed with short IMN, and 2,321 (12.8%) were managed with long IMN. Total cost of IMN added up to £1.89 million in 2021, and the clinical justification for this is unclear since rates of IMN use varied from 0% to 97% in different centres. Conclusion. Most trochanteric hip fractures are managed with SHS, in keeping with national guidelines. There is considerable variance between hospitals for implant choice, despite the lack of evidence for clinical benefit and cost-effectiveness of more expensive nailing systems. This suggests either a lack of awareness of national guidelines or a choice not to follow them. We encourage provider units to reassess their practice if outwith the national norm. Funding bodies should examine implant use closely in this population to prevent resource waste at a time of considerable health austerity. Cite this article: Bone Jt Open 2022;3(10):741–745

Mirels’ score predicts the likelihood of sustaining pathological fractures using pain, lesion site, size and morphology. The aim is to investigate its reproducibility, reliability and accuracy in upper limb bony metastases and validate its use in pathological fracture prediction. A retrospective cohort study of patients with upper limb metastases, referred to an Orthopaedic Trauma Centre (2013–18). Mirels’ was calculated in 32 patients; plain radiographs at presentation scored by 6 raters. Radiological aspects were scored twice by each rater, 2-weeks apart. Inter- and intra-observer reliability were calculated (Fleiss’ kappa test). Bland-Altman plots compared variances of individual score components &total Mirels’ score. Mirels’ score of ≥9 did not accurately predict lesions that would fracture (11% 5/46 vs 65.2% Mirels’ score ≤8, p<0.0001). Sensitivity was 14.3% &specificity was 72.7%. When Mirels’ cut-off was lowered to ≥7, patients were more likely to fracture (48% 22/46 versus 28% 13/46, p=0.045). Sensitivity rose to 62.9%, specificity fell to 54.6%. Kappa values for interobserver variability were 0.358 (fair, 0.288–0.429) for lesion size, 0.107 (poor, 0.02–0.193) for radiological appearance and 0.274 (fair, 0.229–0.318) for total Mirels’ score. Values for intraobserver variability were 0.716 (good, 95% CI 0.432–0.999) for lesion size, 0.427 (moderate, 95% CI 0.195–0.768) for radiological appearance and 0.580 (moderate, 0.395–0.765) for total Mirels’ score. We showed moderate to substantial agreement between &within raters using Mirels’ score on upper limb radiographs. Mirels’ has poor sensitivity &specificity predicting upper limb fractures - we recommend the cut-off score for prophylactic surgery should be lower than for lower limb lesions

Aims. The purpose of this study was to identify factors associated with limitations in function, measured by patient-reported outcome measures (PROMs), six to nine months after a proximal humeral fracture, from a range of demographic, injury, psychological, and social variables measured within a week and two to four weeks after injury. Patients and Methods. We enrolled 177 adult patients who sustained an isolated proximal humeral fracture into the study and invited them to complete PROMs at their initial outpatient visit within one week of injury, between two and four weeks, and between six to nine months after injury. There were 128 women and 49 men; the mean age was 66 years (. sd. 16; 18 to 95). In all, 173 patients completed the final assessment. Bivariate analysis was performed followed by multivariable regression analysis accounting for multicollinearity using partial R. 2. , correlation matrices, and variable inflation factor. Results. Many variables within a week of injury and between two and four weeks after injury correlated with six- to nine-month PROMs in bivariate analysis. Kinesiophobia measured within a week of injury (Tampa Scale for Kinesiophobia-11: partial R. 2. = 0.14; p = 0.000) and self-efficacy measured between two and four weeks (Pain Self-efficacy Questionnaire-2: partial R. 2. = 0.266; p < 0.001) were the strongest predictors of limitations (measured by Patient Reported Outcome Measurement Information System Upper Extremity Physical Function Computer Adaptive Test (PROMIS UE)) at six to nine months in multivariable analysis. Similar findings were observed with other types of PROM. Regression models accounted for a substantial amount of variance in all PROMs at both timepoints (e.g. 66% of the overall variance within one week, and 70% within two to four weeks for PROMIS UE at six to nine months). . Conclusion. Recovery from a proximal humeral fracture appears to be enhanced by overcoming fears of movement or reinjury within a week after injury and greater self-efficacy (developing resilience and more effective coping strategies) within a month. Such factors are modifiable using enhanced communication skills and cognitive behavioural treatments. These findings could be a catalyst for the routine assessment and treatment of psychological and social factors in the management of patients with fractures.

Aims. To compare operative and nonoperative treatment for displaced distal radius fractures in patients aged over 65 years. Methods. A total of 100 patients were randomized in this non-inferiority trial, comparing cast immobilization with operation with a volar locking plate. Patients with displaced AO/OTA A and C fractures were eligible if one of the following were found after initial closed reduction: 1) dorsal angulation > 10°; 2) ulnar variance > 3 mm; or 3) intra-articular step-off > 2 mm. Primary outcome measure was the abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) after 12 months. Secondary outcome measures were the Patient-Rated Wrist and Hand Evaluation (PRWHE), EuroQol-5 dimensions 5-level questionnaire (EQ-5D-5L), range of motion (ROM), grip strength, “satisfaction with wrist function” (score 0 to 10), and complications. Results. In all, 89 women and 11 men were included. Mean age was 74 years (65 to 91). Nonoperative treatment was non-inferior to operation with a five-point difference in median QuickDASH after 12 months (p = 0.206). After three and six months QuickDASH favoured the operative group (p = 0.010 and 0.030). Median values for PRWHE were 19 (interquartile range (IRQ) 10 to 32) in the operative group versus ten (IQR 1 to 31) in the nonoperative group at three months (p = 0.064), nine (IQR 2 to 20) versus five (IQR 0 to 13) (p = 0.020) at six months, and two (IQR 0 to 12) versus zero (IQR 0 to 8) (p = 0.019) after 12 months. Range of motion was similar between the groups. The EQ-5D-5L index score was better (mean difference 0.07) in the operative group at three and 12 months (p = 0.008 and 0.020). The complication rate was similar (p = 0.220). The operated patients were more satisfied with wrist function (median 8 (IQR 6 to 9) vs 6 (IQR 5 to 7) at three months, p = 0.002; 9 (IQR 7 to 9) vs 8 (IQR 6 to 8) at six months, p = 0.002; and 10 (IQR 8 to 10) vs 8 (IQR 7 to 9) at 12 months, p < 0.001). Conclusion. Nonoperative treatment was non-inferior to operative treatment based on QuickDASH after one year. Patients in the operative group had a faster recovery and were more satisfied with wrist function. Results from previous trials comparing operative and nonoperative treatment for displaced distal radius fractures in the elderly vary between favouring the operative group and showing similar results between the treatments. This randomized trial suggests that most elderly patients may be treated nonoperatively. Cite this article: Bone Joint J 2021;103-B(2):247–255

Introduction. To introduce a new classification method and analyze related risk factor about lateral wall perforation associated with lower cervical pedicle screw and free-hand insertion technique. Methods. A Retrospective study was made to analyze 214 patients (1024 screws) with various cervical spine disorders, involved in pedicle screw instrumentation at C3-7 from July 2004 to July 2009. Researchers assessed the position of the screws in the pedicle by carefully probing intraoperatively and studying postoperative thin-slice computed tomography scan. Perforation of lateral wall was classified into two phases. Phase I refers to the burst of the pedicle by screw, which means that the length of screw threads penetrating the external cortex of pedicles on CT scan is 2 mm, whereas in Phase, the length is >2 mm. The Penetrated screws and related factors were analyzed though Backward Stepwise (Wald) Logistic regression. Results. During the follow-up, 2 screws were reported to be broken and 1 screw loosened. Of the screws inserted, total of 129 screws 12.60% have shown violated of lateral pedicle walls, included 101 screws (9.86%) causative of Phase I and 28 screws (2.73%) of Phase II. Two variance were deduced in the regression analysis, which concerned to ratio variance between inner and lateral walls, PRC 0.695, OR value = 2.003and angle difference variance between screws implanted and measurements preoperativePRC −1.542, OR value = 0.214). Conclusions. Free-hand lower cervical pedicle screw insertion in this series was comparatively safety. Phase I Penetration was believed to be safe of vertebral artery and Phase II faced to higher risk of artery damage. The main risk factor of lateral wall perforation was the ratio variance between inner and lateral wall, while the main protection factor was the angle difference variance between screws implanted and CT measurements

The patella is a complex sesamoid bone within the quadriceps enhancing mechanical advantage of the extensor mechanism. Depending on activity, the patella magnifies either force or displacement; behaving as a lever, by redirecting quadriceps force it also acts as a pulley. Aim. We describe and validate a device for obtaining consistent dynamic weight bearing views of the patellofemoral joint (PFJ). Materials and Methods. Weight bearing (WB) axial views of 48 knees (24 patients) were performed using the device. The sulcus angle (SA), congruence angle (CA), lateral patellofemoral angle (LPFA), facet angle (FA) and patellofemoral displacement (PD) were measured. These were compared with similar measurements made on prone (PR) and axial (AX) radiographs of same knees. Results. Variance (V=SD2) and Standard error of mean (SEM/95% CI) for all measurements in each of the three views were analysed. For the Sulcus Angle, Congruence angle and LPFA, the WB view had the lowest SEM and the least variance in comparison to PR and AX views (SEM 1.05/V 30.14, SEM 2.52/V 172.39 and SEM 1.34/V 47.61 respectively for the SA, SEM 3.09/V 256, SEM 2.79/V 210.25 and SEM 3.37/V 306.25 respectively for the CA, SEM 0.67/V 11.9, SEM 1.20/V39.06 and SEM 1.03/V 28.83 respectively for the LPFA). SEM and Variance for FA measurements were similar for WB and AX views but superior to PR views (SEM 1.62/V 70.56, SEM 1.6/V 68.9 and SEM 2.3/V 148.84 respectively). Mean PFD was maximum on the WB view compared to the PR and AX views (36.0, −45.62 and 22.23 respectively) with lowest SEM and V (SEM 8.73/V 2052.0, SEM 18.65/V 92959.67 and SEM 9.70/V 2540.16 respectively). Conclusion. The WB view as introduced and reported here has consistently lower Variance, SEM and SD in comparison to Axial and Prone views for all measurements of the PFJ. WB view also gives a more accurate dynamic measure of Patello Femoral displacement. The view is easily obtained and readily reproduced

A total of 118 consecutive patients with a fracture of the distal radius were treated with a volar locking plate; 50 patients had no ulnar styloid fracture, 41 had a basal ulnar styloid fracture, and 27 had a fracture of the tip of the ulnar styloid. There were no significant differences in radiological and clinical results among the three groups. The outcome was good and was independent of the presence of a fracture of the ulnar styloid. A total of five patients (4.2%) had persistent ulnar-sided wrist pain at final follow-up. Nonunion of the ulnar styloid fracture did not necessarily lead to ulnar wrist pain. Patients with persistent ulnar pain had a higher mean initial ulnar variance and increased post-operative loss of ulnar variance. The presence of an associated ulnar styloid fracture of the ulnar styloid does not adversely affect the outcome in patients with a fracture of the distal radius treated by volar plating

Aims

Tobacco, in addition to being one of the greatest public health threats facing our world, is believed to have deleterious effects on bone metabolism and especially on bone healing. It has been described in the literature that patients who smoke are approximately twice as likely to develop a nonunion following a non-specific bone fracture. For clavicle fractures, this risk is unclear, as is the impact that such a complication might have on the initial management of these fractures.

Aims

Fracture-related infections (FRIs) are a devastating complication of fracture management. However, the impact of FRIs on mental health remains understudied. The aim of this study was a longitudinal evaluation of patients’ psychological state, and expectations for recovery comparing patients with recurrent FRI to those with primary FRI.

Aims

The aims of this study were to identify means to quantify coronal plane displacement associated with distal radius fractures (DRFs), and to understand their relationship to radial inclination (RI).

Aims

Prior to the availability of vaccines, mortality for hip fracture patients with concomitant COVID-19 infection was three times higher than pre-pandemic rates. The primary aim of this study was to determine the 30-day mortality rate of hip fracture patients in the post-vaccine era.

Aims

To determine if patient ethnicity among patients with a hip fracture influences the type of fracture, surgical care, and outcome.

Aims

The use of multimodal non-opioid analgesia in hip fractures, specifically acetaminophen combined with non-steroidal anti-inflammatory drugs (NSAIDs), has been increasing. However, the effectiveness and safety of this approach remain unclear. This study aimed to compare postoperative outcomes among patients with hip fractures who preoperatively received either acetaminophen combined with NSAIDs, NSAIDs alone, or acetaminophen alone.

Hip fracture care is complex multi-disciplinary. We hypothesise that quality of care is affected by variance in resources between ‘in-hours’ (Monday-Friday, 0800–1700) and ‘out-of-hours’ services. This prospective multicentre national cohort study assessed quality of care by evaluating adherence to the evidence-based Scottish Standards of Care for Hip Fracture Patients. Data was collected by the Scottish Hip Fracture Audit for 15174 patients admitted to any of 22 Scottish hospitals from January 2014-April 2018. 11197/15174 (73.8%) patients were admitted out-of-hours. They were significantly less likely to meet the following Standards: ED Big-6-Bundle (OR 0.85, p= 0.002); Time in ED <4 hours (OR 0.76, p< 0.001); avoidance of repeated fasting (OR 0.80, p< 0.001), and avoidance of prolonged fluid fasting (OR 0.83, p< 0.001). Out-of-hours admissions were more likely to receive: geriatric assessment <3 days (OR 1.16, p< 0.001); OT input <3 days (OR 1.10, p= 0.013), and PT input <2 days (OR 1.44, p< 0.001). There were no significant differences for: Time to Theatre <36 hours; Inpatient Care Bundle <24 hours, and Post-op Day 1 Mobilisation. Quality of hip fracture care is affected by time of admission. ED care is poorer out-of-hours, which may reflect limited resources, and out-of-hours admissions are more likely to be excessive fasted excessively. Weekday in-hours admissions are less likely to receive geriatric and allied health professional input in the days following admission, which may reflect the reduced weekend services. Examination of out-of-hours service organisation is required for the pursuit of consistent, equitable care for hip fracture patients

Aims

Frailty greatly increases the risk of adverse outcome of trauma in older people. Frailty detection tools appear to be unsuitable for use in traumatically injured older patients. We therefore aimed to develop a method for detecting frailty in older people sustaining trauma using routinely collected clinical data.

Aims

In the Netherlands, general practitioners (GPs) can request radiographs. After a radiologically diagnosed fracture, patients are immediately referred to the emergency department (ED). Since 2020, the Máxima Medical Centre has implemented a new care pathway for minor trauma patients, referring them immediately to the traumatology outpatient clinic (OC) instead of the ED. We investigated whether this altered care pathway leads to a reduction in healthcare consumption and concomitant costs.

Aims

Acetabular fractures are associated with long-term morbidity. Our prospective cohort study sought to understand the recovery trajectory of this injury over five years.

Aims

Though most humeral shaft fractures heal nonoperatively, up to one-third may lead to nonunion with inferior outcomes. The Radiographic Union Score for HUmeral Fractures (RUSHU) was created to identify high-risk patients for nonunion. Our study evaluated the RUSHU’s prognostic performance at six and 12 weeks in discriminating nonunion within a significantly larger cohort than before.
