Racial Disparities in the Operative Management of Orthopedic Trauma: A Systematic Review and Meta-Analysis.

OBJECTIVE: The objective of this study was to investigate if race is associated with the likelihood of operative management of acute fractures. METHODS: A systematic review of the literature was performed using the PubMed, EMBASE, and Cochrane databases to identify studies associated with social disparities and acute orthopedic trauma. Peer-reviewed studies commenting on social disparities and the decision to pursue operative or non-operative management of acute fractures were identified for detailed review. Study characteristics and odds ratios were extracted from each article. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed. A quality analysis of the data was also performed. RESULTS: In total, 13 studies were identified and 8 were included in the meta-analysis totaling 743,846 fractures. Hip, distal radius, pelvic, tibial plateau, clavicle, femoral neck, and femoral shaft fractures were represented in this patient population. The meta-analysis demonstrated that White race is associated with a higher likelihood of operative intervention compared to all other races pooled together (odds ratio, 1.31; 95% confidence interval 1.16 to 1.47; p < .0001) as well as Black race (odds ratio 1.39; 95% confidence interval 1.12 to 1.72; p = .0025). CONCLUSIONS: Non-White race and Black race are associated with a lower likelihood of receiving surgical management of acute orthopedic trauma. Surgeons and health systems should be aware of these inequities and consider strategies to mitigate bias and ensure all patients receive appropriate and timely care regardless of race.

Surgical fixation with K-wires versus casting in adults with fracture of distal radius: DRAFFT2 multicentre randomised clinical trial.

OBJECTIVE: To assess wrist function, quality of life, and complications in adult patients with a dorsally displaced fracture of the distal radius, treated with either a moulded cast or surgical fixation with K-wires. DESIGN: Multicentre randomised clinical superiority trial, SETTING: 36 hospitals in the UK National Health Service (NHS). PARTICIPANTS: 500 adults aged 16 or over with a dorsally displaced fracture of the distal radius, randomised after manipulation of their fracture (255 to moulded cast; 245 to surgical fixation). INTERVENTIONS: Manipulation and moulded cast was compared with manipulation and surgical fixation with K-wires plus cast. Details of the application of the cast and the insertion of the K-wires were at the discretion of the treating surgeon, according to their normal clinical practice. MAIN OUTCOME MEASURES: The primary outcome measure was the Patient Rated Wrist Evaluation (PRWE) score at 12 months (five questions about pain and 10 about function and disability; overall score out of 100 (best score=0 and worst score=100)). Secondary outcomes were PRWE score at three and six months, quality of life, and complications, including the need for surgery due to loss of fracture position in the first six weeks. RESULTS: The mean age of participants was 60 years and 417 (83%) were women; 395 (79%) completed follow-up. No statistically significant difference in the PRWE score was seen at 12 months (cast group (n=200), mean 21.2 (SD 23.1); K-wire group (n=195), mean 20.7 (22.3); adjusted mean difference -0.34 (95% confidence interval -4.33 to 3.66), P=0.87). No difference was seen at earlier time points. In the cast group, 33 (13%) of participants needed surgical fixation for loss of fracture position in the first six weeks compared with one revision surgery in the K-wire group (odds ratio 0.02, 95% confidence interval 0.001 to 0.10). CONCLUSIONS: Among patients with a dorsally displaced distal radius fracture that needed manipulation, surgical fixation with K-wires did not improve patients' wrist function at 12 months compared with a cast.

Surgical stabilization of severe chest wall injury following cardiopulmonary resuscitation.

BACKGROUND: Cardiopulmonary resuscitation (CPR) contributes to significant chest wall injury similar to blunt trauma. With benefits realized for surgical stabilization of rib fractures (SSRFs) for flail injuries and severely displaced fractures following trauma, SSRF for chest wall injury following CPR could be advantageous, provided good functional and neurologic outlook. Experience is limited. We present a review of patients treated with SSRF at our institution following CPR. METHODS: A retrospective analysis of patients undergoing SSRF following CPR was performed between 2019 and 2020. Perioperative inpatient data were collected with outpatient follow-up as able. RESULTS: Five patients underwent SSRF over the course of the 2-year interval. All patients required invasive ventilation preoperatively or had impending respiratory. Mean age was 59 ± 12 years, with all patients being male. Inciting events for cardiac arrest included respiratory, ventricular tachycardia, ventricular fibrillation, pulseless electrical activity, and anaphylaxis. Time to operation was 6.6 ± 3 days. Four patients demonstrated anterior flail injury pattern with or without sternal fracture, with one patient having multiple severely displaced fractures. Surgical stabilization of rib fracture was performed appropriately to restore chest wall stability. Mean intensive care unit length of stay was 9.8 ± 6.4 days and overall hospital length of stay 24.6 ± 13.2 days. Median postoperative ventilation was 2 days (range, 1-15 days) with two patients developing pneumonia and one requiring tracheostomy. There were no mortalities at 30 days. One patient expired in hospice after a prolonged hospitalization. Disposition destination was variable. No hardware complications were noted on outpatient follow-up, and all surviving patients were home. CONCLUSION: Chest wall injuries are incurred frequently following CPR. Surgical stabilization of these injuries can be considered to promote ventilator liberation and rehabilitation. Careful patient selection is paramount, with surgery offered to those with reversible causes of arrest and good functional and neurologic outcome. Experience is early, with further investigation needed. LEVEL OF EVIDENCE: Therapeutic, Level V.

Charges, length of stay, and complication associations with trauma center ownership in adult patients with mild to moderate trauma.

BACKGROUND: For-profit (FP) trauma centers (TCs) charge more for trauma care than not-for-profit (NFP) centers. We sought to determine charges, length of stay (LOS), and complications associations with TC ownership status (FP, NFP, and government) for three diagnoses among patients with overall low injury severity. METHODS: Adult patients treated at TCs with an International Classification of Diseases-based injury severity score (ICISS) survival probability ≥ 0.85 were identified. Only those who with a principal diagnosis of femur, tibial or rib fractures were included. RESULTS: Total charges were significantly higher at FP centers than NFP and lower at government centers (89.6% and -12.8%, respectively). FP TCs had a 12.5% longer LOS and government TCs had a 20.4% longer LOS than NFP TCs. CONCLUSION: Patients presenting to FP TCs with mild/moderate femur, tibial, or rib fractures experienced higher charges and increased LOS compared with government or NFP centers. There was no difference in overall complication rates.

Mapping of common rib fracture patterns and the subscapular flail chest associated with operative scapula fractures.

BACKGROUND: Rib fractures occur in approximately 10% of trauma patients and are associated with more than 50% of patients with scapula fractures. This study investigates the location and patterns of rib fractures and flail chest occurring in patients with operatively treated scapula fractures. Novel frequency mapping techniques of rib fracture patterns in patients who also injure the closely associated scapula can yield insight into surgical approaches and fixation strategies for complex, multiple injuries patients. We hypothesize that rib fractures have locations of common occurrence when presenting with concomitant scapula fracture that requires operative treatment. METHODS: Patients with one or more rib fractures and a chest computed tomography scan between 2004 and 2018 were identified from a registry of patients having operatively treated scapula fractures. Unfurled rib images were created using Syngo-CT Bone Reading software (Siemens Inc., Munich, Germany). Rib fracture and flail segment locations were marked and measured for standardized placement on a two-dimensional chest wall template. Location and frequency were then used to create a gradient heat map. RESULTS: A total of 1,062 fractures on 686 ribs were identified in 86 operatively treated scapula fracture patients. The mean ± SD number of ribs fractured per patient was 8.0 ± 4.1 and included a mean ± SD of 12.3 ± 7.2 total fractures. Rib fractures ipsilateral to the scapula fracture occurred in 96.5% of patients. The most common fracture and flail segment location was ipsilateral and subscapular; 51.4% of rib fractures and 95.7% of flail segments involved ribs 3 to 6. CONCLUSION: Patients indicated for operative treatment of scapula fractures have a substantial number of rib fractures that tend to most commonly occur posteriorly on the rib cage. There is a pattern of subscapular rib fractures and flail chest adjacent to the thick bony borders of the scapula. This study enables clinicians to better evaluate and diagnose scapular fracture patients with concomitant rib fractures. LEVEL OF EVIDENCE: Diagnostic test, level IV.

Long-term pulmonary function, thoracic pain, and quality of life in patients with one or more rib fractures.

BACKGROUND: Long-term outcomes after rib fractures and the effect of treatment modality or chest wall injury severity on these outcomes remains uncertain. This retrospective cohort study evaluated the long-term pulmonary function, thoracic pain, and quality of life in patients admitted with rib fractures. METHODS: Patients admitted with rib fractures between January 1, 2012, and December 1, 2019, were included. Data on long-term outcomes were collected during one follow-up visit. Patients were stratified by chest wall injury severity (one or two rib fractures, ≥3 rib fractures, or a flail chest) and treatment modality (surgical stabilization of rib fractures [SSRF] or nonoperative management). Multivariable analysis was performed to compare outcomes after SSRF with nonoperative treatment in patients with three or more rib fractures. RESULTS: In total, 300 patients were included. The median follow-up was 39 months (P25-P75, 18-65 months). At follow-up, the corrected forced vital capacity returned to 84.7% (P25-P75, 74.3-93.7) and the forced expiratory volume in 1 second to 86.3% (P25-P75, 75.3-97.0) of the predicted reference values. Quality of life was determined using the Short Form-12 version 2 and EuroQoL-5D-5L. The Short Form-12 version 2 physical and mental component summary were 45 (P25-P75, 38-54) and 53 (P25-P75, 43-60), respectively. The EuroQoL-5D-5L utility score was 0.82 (P25-P75 0.66-0.92) and visual analog scale score 75 (P25-P75 70-85). This indicated a quality of life within normal population ranges. Moderate to severe thoracic pain was reported by 64 (21.3%) patients. Long-term outcomes returned to values within population ranges and were similar across chest wall injury severity and for patients treated with SSRF or nonoperatively. CONCLUSION: While long-term pulmonary function and quality of life recover to values considered normal, subjective thoracic complaints, such as pain and dyspnea, remain frequently present following rib fractures. No effect of chest wall injury severity or treatment modality on long-term outcomes was demonstrated. LEVEL OF EVIDENCE: Therapeutic, level III.

Hip Fracture Following a Fall among Older Adults during the COVID-19 Pandemic.

BACKGROUND: Little is known regarding the impact of the coronavirus disease-2019 (COVID-19) pandemic on the incidence of hip fractures among older adults. OBJECTIVES: To compare the characteristics of patients with a hip fracture following a fall during the COVID-19 pandemic year and during the preceding year. METHODS: We conducted a retrospective cohort study of older patients who had undergone surgery for hip fracture repair in a major 495-bed hospital located in northern central Israel following a fall. Characteristics of patients who had been hospitalized in 2020 (pandemic year, n=136) and in 2019 (non-pandemic year, n=151) were compared. RESULTS: During the pandemic year, patients were less likely to have fallen in a nursing facility, to have had muscle or balance problems, and to have had a history of falls and fractures following a fall. Moreover, the average length of stay (LOS) in the hospital was shorter; however, the average time from the injury to hospitalization was longer. Patients were less likely to have acquired a postoperative infection or to have died. During the pandemic year, postoperative infection was only associated with prolonged LOS. CONCLUSIONS: The COVID-19 pandemic may have had a positive impact on the behavior of older adults as well as on the management of hip fracture patients. However, healthcare providers should be aware of the possible reluctance to seek care during a pandemic. Moreover, further research on the impact of the change in management during COVID-19 on hip fracture survival is warranted.

Prediction of Long Bone Fractures in Multiple Myeloma Patients in an Advanced Imaging World.

BACKGROUND: Multiple myeloma (MM) affects the long bones in 25% of patients. The advent of positron-emission tomography/computed tomography (PET/CT) scanners offers the possibility of both metabolic and radiographic information and may help determine fracture risk. To the best of our knowledge, no published study correlates these two factors with long bone fractures. OBJECTIVES: To evaluate the impact of PET/CT on fracture risk assessment in multiple myeloma patients. METHODS: We identified all bone marrow biopsy proven multiple myeloma patients from 1 January 2010 to 31 January 2015 at a single institution. We prospectively followed patients with long bone lesions using PET/CT scan images. RESULTS: We identified 119 patients (59 males/60 females) with 256 long bone lesions. Mean age at diagnosis was 58 years. The majority of lesions were in the femur (n=150, 59%) and humerus (n=84, 33%); 13 lesions in 10 patients (8%) required surgery for impending (n=4) or actual fracture (n=9). Higher median SUVmax was measured for those with cortical involvement (8.05, range 0-50.8) vs. no involvement (5.0, range 2.1-18.1). SUVmax was found to be a predictor of cortical involvement (odds ratio = 1.17, P = 0.026). No significant correlation was found between SUVmax and pain or fracture (P = 0.43). CONCLUSIONS: Improved medical treatment resulted improvement in 8% of patients with an actual or impending fracture. The orthopedic surgeons commonly use the Mirels classification for long bone fracture prediction. Adding PET/CT imaging to study in myeloma long bone lesions did not predict fracture risk directly but suggested it indirectly by cortical erosion.

Relationship between Charlson comorbidity index, early recovery and 2-year mortality in elderly patients undergoing surgical treatment of inter-trochanteric fractures: a retrospective analysis.

The aim of this study was to evaluate how the Charlson Comorbidity Index (CCI) scores contribute to early recovery and 2-year mortality in elderly patients undergoing surgical treatment of inter-trochanteric fractures. 60 cases with unilateral intertrochanteric fracture were retrospectively analyzed and divided into Low-CCI group (CCI: 1-4) or high-CCI groups (CCI: 5-6). All the patients' electronic hospital records were reviewed. The preoperative situations (demographic data, comorbidities and fracture conditions), perioperative situations (wait time, operation time, implant choice, blood loss, transfusion or not) and postoperative situations (complications, first time out of bed, function about 1-/2- week and 2-year mortality) were recorded. 51.67% were in low-CCI group and 48.33% in high-CCI group. The survival rates in low- and high-CCI group were 93.5% and 86.2% respectively. According to the functional results of 1- or 2- week after operation, no significant difference was found (P = 0.955, 0.140). Log-rank analysis showed that the main prognostic factors were blood loss, first time out of bed and complication (P < 0.05). Multivariate analysis confirmed that complication and first time out of bed were significant factor on survival rate (P = 0.029, 0.010). Charlson comorbidity index maybe not the indicator of 2-year mortality in older patients with intertrochanteric fractures. In order to improve the prognosis, more attentions should be paid to reduce the complications and encourage postoperative earlier excise out of bed.

Surgical stabilization of traumatic rib fractures is associated with reduced readmissions and increased survival.

BACKGROUND: Surgical stabilization for rib fractures (SSRF) in trauma patients remains controversial, with guidelines currently suggesting the procedure for only select patient groups. How surgical stabilization for rib fractures affect hospital readmission in patients with traumatic rib fractures is unknown. We hypothesized that surgical stabilization for rib fractures would not decrease the risk of readmission. METHODS: The National Readmission Database was examined for adults with any rib fractures from 2010 to 2017. Readmission up to 90 days was examined. Patients receiving surgical stabilization for rib fractures were compared with those receiving nonoperative treatment. RESULTS: In total, 864,485 patients met criteria, with 13,701 (1.6%) receiving SSRF. For patients receiving SSRF, 338 (1.5%) were readmitted. Readmitted patients had higher Charlson Comorbidity Index and were more likely to have flail chest. On multivariate propensity score-matched analysis, SSRF (Hazard Ratio [HR]: 0.55, 95% confidence interval [CI] 0.33-0.92, P = .022) was associated with reduced readmission. Addition of surgical stabilization for rib fractures to video-assisted thoracoscopic surgery (VATS) (Odds Ratio [OR]: 0.95, 95% CI 0.52-1.73, P = .86) or thoracotomy (OR: 1.97, 95% CI 0.83-4.70, P = .13) was not associated with increased readmission. On further propensity matched analysis, VATS + SSRF when compared with SSRF alone (HR: 0.75, 95% CI 0.18-3.20, P = .696), and VATS + SSRF when compared with VATS alone (HR: 0.49, 95% CI 0.11-2.22, P = .355) was also not associated with increased readmission. SSRF on primary admission was associated with increased in-hospital survival (HR: 0.27, 95% CI 0.22-0.32, P < .001). For patients with retained hemothorax who underwent VATS, addition of SSRF did not improve survival (HR = 0.92, 95% CI 0.58-1.46, P = .72). However, for patients requiring thoracotomy for retained hemothorax, concomitant SSRF was associated with improved survival (HR = 0.14, 95% CI 0.06-0.32, P < .001). CONCLUSION: Surgical stabilization for rib fractures is associated with reduced readmission risk while also being associated with improved survival. Patients who had a thoracotomy for retained hemothorax appear to especially benefit from concomitant surgical stabilization for rib fractures.

Surgical stabilization of rib fractures in octogenarians and beyond-what are the outcomes?

BACKGROUND: Prospective studies of surgical stabilization of rib fractures (SSRF) have excluded elderly patients, and no study has exclusively addressed the ≥80-year-old subgroup. We hypothesized that SSRF is associated with decreased mortality in trauma patients 80 years or older. METHODS: Multicenter retrospective cohort study involving eight centers. Patients who underwent SSRF from 2015 to 2020 were matched to controls by study center, age, injury severity score, and presence of intracranial hemorrhage. Patients with chest Abbreviated Injury Scale score less than 3, head Abbreviated Injury Scale score greater than 2, death within 24 hours, and desire for no escalation of care were excluded. A subgroup analysis compared early (0-2 days postinjury) to late (3-7 days postinjury) SSRF. Poisson regression accounting for clustered data by center calculated the relative risk (RR) of the primary outcome of mortality for SSRF versus nonoperative management. RESULTS: Of 360 patients, 133 (36.9%) underwent SSRF. Compared with nonoperative patients, SSRF patients were more severely injured and more likely to receive locoregional analgesia. There were 31 hospital deaths among the entire sample (8.6%). Multivariable regression demonstrated a decreased risk of mortality for the SSRF group, as compared with the nonoperative group (RR, 0.41; 95% confidence interval, 0.24-0.69; p < 0.01). However, SSRF patients were more likely to develop pneumonia, and had an increased duration of both mechanical ventilation and intensive care unit stay. There were no differences in discharge destination, although the SSRF group was less likely to be discharged on narcotics (RR, 0.66; 95% confidence interval, 0.48-0.90; p = 0.01). There was no difference in adjusted mortality between the early and late SSRF subgroups. CONCLUSION: Patients selected for SSRF were substantially more injured versus those managed nonoperatively. Despite this, SSRF was independently associated with decreased mortality. With careful patient selection, SSRF may be considered a viable treatment option in octogenarian/nonagenarians. LEVEL OF EVIDENCE: Therapeutic, Level IV.

Delay in Hip Fracture Repair in the Elderly: A Missed Opportunity Towards Achieving Better Outcomes.

BACKGROUND: Hip fractures are a major cause of morbidity and mortality in the elderly. The American Academy of Orthopedic Surgeons (AAOS) recommends surgical repair within 48 hours of admission, as this is associated with lower postoperative mortality and complications. This study demonstrates the association between patient demographics, level of care, and hospital region to delay in hip fracture repair in the elderly. METHODS: The National Trauma Data Bank (NTDB) was queried for elderly patients (age >65 years) who underwent proximal femoral fracture repair. Identified patients were subcategorized into two groups: hip fracture repair in <48 hours, and hip fracture repair > 48 hours after admission. Patient and hospital characteristics were collected. Outcome variables were timed from the day of admission to surgery and inpatient mortality. RESULTS: Out of 69,532 patients, 28,031 were included after inclusion criteria were applied. 23,470 (83.7%) patients underwent surgical repair within 48 hours. The overall median time to procedure was 21 (interquartile range [IQR] 7-38) hours. Females were less likely to undergo a delay in hip fracture repair (odds ratio [OR; 95% confidence interval {CI}]: 0.82 [0.76-0.88], P< 0.05), and patients with higher Injury Severity Score (ISS ≥25) had higher odds of delay in surgical repair (OR; 95% CI: 1.56 [1.07-2.29], P< 0.05). Patients treated at hospitals in the Western regions of the United States had lower odds of delay, and those treated in the Northeast and the South had higher odds of delay compared to the hospitals in the Midwest (taken as standard). There was no association between trauma level designation and odds of undergoing delay in hip fracture repair. CONCLUSION: Variables related to patient demographic and hospital characteristics are associated with delay in hip fracture repair in the elderly. This study delineates key determinants of delay in hip fracture repair in the elderly patients.

Pelvic and acetabular fracture care in England: current workload and future directions.

INTRODUCTION: Fractures of the pelvis and acetabulum (PAFs) are challenging injuries, requiring specialist surgical input. Since implementation of the major trauma network in England in 2012, little has been published regarding the available services, workforce organisation and burden of PAF workload. The aim of this study was to assess the recent trends in volume of PAF workload, evaluate the provision of specialist care, and identify variation in available resources, staffing and training opportunity. METHODS: Data on PAF volume, operative caseload, route of admission and time to surgery were requested from the Trauma Audit and Research Network. In order to evaluate current workforce provision and services, an online survey was distributed to individuals known to provide PAF care at each of the 22 major trauma centres (MTCs). RESULTS: From 2013 to 2019, 23,823 patients with PAF were admitted to MTCs in England, of whom 12,480 (52%) underwent operative intervention. On average, there are 3,971 MTC PAF admissions and 2,080 operative fixations each year. There has been an increase in admissions and cases treated operatively since 2013. Three-quarters (78%) of patients present directly to the MTC while 22% are referred from regional trauma units. Annually, there are on average 37 operatively managed PAF injuries per million population. Notwithstanding regional differences in case volume, the average number of annual PAF operative cases per surgeon in England is 30. There is significant variation in frequency of surgeon availability. There is also variation in rota organisation regarding consistent specialist surgeon availability. CONCLUSIONS: This article describes the provision of PAF services since the reorganisation of trauma services in England. Future service development should take into account the current distribution of activity, future trends for increased volume and casemix, and the need for a PAF registry.

Low-energy Gunshot-induced Tibia Fractures: What Proportion Develop Complications?

BACKGROUND: Gunshot injuries of the extremities are common in the United States, especially among people with nonfatal gunshot wounds. Controversy persists regarding the proper management for low-energy gunshot-induced fractures, likely stemming from varying reports on the likelihood of complications. There has yet to be published a study on a large cohort of patients with gunshot-induced tibia fractures on which to base our understanding of complications after this injury. QUESTIONS/PURPOSES: (1) What percentage of patients with low-energy gunshot-induced tibia fractures developed complications? (2) Was there an association between deep infection and fracture location, injury characteristics, debridement practices, or antibiotic use? METHODS: This was a multicenter retrospective study. Between January 2009 and December 2018, we saw 201 patients aged 16 years or older with a gunshot-induced fracture who underwent operative treatment; 2% (4 of 201) of those screened had inadequate clinical records, and 38% (76 of 201) of those screened had inadequate follow-up for inclusion. In all, 121 patients with more than 90 days of follow-up were included in the study. Nonunion was defined as a painful fracture with inadequate healing (fewer than three cortices of bridging bone) at 6 months after injury, resulting in revision surgery to achieve union. Deep infection was defined according to the confirmatory criteria of the Fracture-Related Infection Consensus Group. These results were assessed by a fellowship-trained orthopaedic trauma surgeon involved with the study. Complication proportions were tabulated. A Kaplan-Meier chart demonstrated presentations of deep infection by fracture location (proximal, shaft, or distal). Univariate statistics and multivariate Cox regression were used to examine the association between deep infection and fracture location, entry wound size, vascular injury, intravenous (IV) antibiotics in the emergency department (ED), deep and superficial debridement, the duration of postoperative IV antibiotics, and the use of topical antibiotics, while adjusting for age, race/ethnicity, smoking status, and BMI. A power analysis for the result of deep infection demonstrated that we would have had to observe a hazard ratio of 4.28 or greater for shaft versus proximal locations to detect statistically significant results at 80% power and alpha = 0.05. RESULTS: The overall complication proportion was 49% (59 of 121), with proportions of 14% (17 of 121) for infection, 27% (33 of 121) for wound complications, 20% (24 of 121) for nonunion, 9% (11 of 121) for hardware breakage, and 26% (31 of 121) for revision surgery. A positive association was present between deep infection and deep debridement (HR 5.51 [95% confidence interval 1.12 to 27.9]; p = 0.04). With the numbers available, we found no association between deep infection and fracture location, entry wound size, vascular injury, IV antibiotics in the ED, superficial debridement, the duration of postoperative IV antibiotics, and the use of topical antibiotics. CONCLUSION: In this multicenter study, we found a higher risk of complications in operative gunshot-induced tibia fractures than prior studies have reported. Infection, in particular, was much more common than expected based on prior studies. Consequently, surgeons might consider adopting the general management principles for nongunshot-induced open tibia fractures with gunshot-induced fractures, such as the use of IV antibiotics both initially and after surgery. Further research is needed to test and validate these approaches. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Hip fracture care during the 2020 COVID-19 first-wave: a review of the outcomes of hip fracture patients at a Scottish Major Trauma Centre.

BACKGROUND AND PURPOSE OF THE STUDY: This study reviewed whether the response to the Coronavirus (COVID-19) pandemic affected the care for hip fracture patients at a major trauma centre in Scotland during the first-wave lock-down period. METHODS: All patients referred to Orthopaedics with a hip fracture in a major trauma centre in Scotland were captured between 14 th March and 28 th May (11 weeks) in 2020 and 2019. Patients were identified using electronic patient records. The primary outcomes are time to theatre, length of admission and 30-day mortality. Secondary outcomes are COVID-19 prevalence, duration of surgery, proportion of patients to theatre within 36 hours and COVID-19 positive 30-day mortality from time of surgery. 225 patients were included: 108 from 2019 and 117 from 2020. THE MAIN FINDINGS: 30-day mortality was 3.7% (n=4) in 2019 and 8.5% (n=10) in 2020 (p=0.142). There was no statistical difference with time to theatre (p=0.150) nor duration of theatre (p=0.450). Duration of admission was reduced from 12 days to 6.5 days (p=<0.005). 4 patients tested positive for COVID-19 during admission, one 5 days after discharge, all underwent surgical management. 30-day mortality for COVID-19 positive patients during admission was 40%. COVID-19 prevalence of patients that were tested (n=89) was 5.62%. CONCLUSIONS: This study has shown the care of hip fracture patients has been maintained during the COVID-19 pandemic. There is no statistically significant change in mortality, time to theatre, and duration of surgery, however, the patient's admission duration was significantly less than the 2019 cohort.

Management of acute paediatric fractures treated surgically in the UK: a cross-sectional study.

INTRODUCTION: The epidemiology of acute paediatric orthopaedic trauma managed surgically across the NHS is poorly described. Compliance against national standards for the management of supracondylar humeral fractures is also unknown at a national level. METHODS: Collaborators in 129 NHS hospitals prospectively collected data on surgically managed acute paediatric orthopaedic trauma cases. Data were collected over a seven-day period and included demographics, injury characteristics, operative details and timing of surgery. A national audit was also undertaken to evaluate compliance with the British Orthopaedic Association Standards for Trauma Guideline 11: Supracondylar Fractures of the Humerus in Children. RESULTS: Data were captured on 770 surgically treated cases. The three most common injuries were forearm fractures of both bones (n = 235), distal radius fractures (n = 194) and supracondylar elbow fractures (n = 89). The mode day of injury was Friday (n = 136) and the mode day of surgery was Saturday (n = 138). 88% of supracondylar fractures received surgery on the day of presentation or the following day. Only 14% of supracondylar fractures were treated surgically after 8pm; 33/89 used 2.0mm Kirschner wires, 38/89 used 1.6mm wires and 2/89 used 1.2mm wires. CONCLUSION: Forearm fractures of both bones, distal radius fractures and supracondylar humeral fractures were the three most common injuries treated surgically. There is wide variation in compliance against national standards in the management of supracondylar humeral fractures with 88% undertaking surgery on the day of or the day following presentation but only 37% using the recommended 2.0mm Kirschner wires.

Ex vivo comparison of standing and recumbent repair of incomplete parasagittal fractures of the first phalanx in horses.

OBJECTIVE: To assess suspensory ligament extensor branch location and fracture gap reduction with simulation of standing and recumbent cortical bone screw repair of experimental incomplete parasagittal proximal phalanx (P1) fractures. STUDY DESIGN: Controlled laboratory study. SAMPLE POPULATION: Twenty equine cadaver forelimbs. METHODS: Simulated fractures were repaired twice in random order. A proximal cortical bone screw was placed in lag fashion with the limb unloaded (simulated recumbent repair) and loaded to 38% of body weight (range, 375-568 kg; simulated standing repair). Changes in fracture gap width were assessed on computed tomography (CT) images and with intraplanar force-sensitive resistors measuring voltage ratios (V△ ) between loaded recumbent (R-1) and standing repair simulations (R-2). Extensor branch borders were determined relative to implant position and sagittal P1 width on transverse CT images. P ≤ .05 was considered significant. RESULTS: Standing repair simulation-associated fracture gaps were not wider than in R-1 while controlling for confounding factors (loading weight, implant position, or animal age; P > .7, repeated-measures analysis of variance). Voltage ratio data associated with R-2 were not smaller than with R-1 (mean difference, 0.002 ± 0.052; one-sided Wilcoxon signed-rank test, P = .27). More of P1 width was approachable palmar to extensor branches when limbs were loaded (0.804 ± 0.314 cm) vs unloaded (0.651 ± 0.31 cm; paired Student's t test, P < .001). CONCLUSION: Simulated standing repair was not associated with inferior fracture reduction compared with loaded simulations of recumbent repairs. Limb loading affected extensor branch location relevant to implant positioning. CLINICAL SIGNIFICANCE: Unloading during standing repair of incomplete parasagittal proximal P1 fractures may not be required to optimize fracture reduction.

Closed reduction percutaneous pinning versus open reduction internal fixation in the treatment of intraarticular distal radius fractures: Mean four-year results.

BACKGROUND: This study was performed to compare the results of closed reduction percutaneous pinning (CRPP) versus open reduction internal fixation with a volar locking plate (ORIF) in the treatment of intraarticular distal radius fractures (IDRF) average four-year follow-up. METHODS: In this study, 43 patients had unilateral intraarticular distal radius fractures (type B and C) treated with CRPP (n=19; 11 males and eight females) and ORIF (n=24; 14 males and 10 females) were retrospectively evaluated. The mean follow-up was 50.3 months (12-74) at the CRPP group and 45.2 months (40-65) at the ORIF group. The mean age was 50.8 years (29-73) in the CRPP group and 51.5 (19-75) in the ORIF group. The patients were evaluated functionally and radiologically at the last follow-up. RESULTS: There was no statistically significant difference between the groups concerning follow-up, age, and gender. However, there was no statistical difference concerning grip power and the range of motion. The Disabilities of the Arm, Shoulder and Hand Score (Q-DASH) was better in the ORIF group. Voler tilt and radial height measurements were statistically significantly better in the ORIF group. Degenerative arthritis was 63% in the CRPP group and 41% in the ORIF group, and there was no statistically significant difference. CONCLUSION: ORIF with a volar locking plate has better functional and radiological results than CRPP in IDRF patients' average four-year follow-up.
