To determine whether inpatient mobilization (defined as ambulation before hospital discharge) is associated with 1-year mortality and 90-day hospital readmission in patients treated with a hip hemiarthroplasty for a femoral neck fracture.Retrospective case-control.Academic Level 1 trauma center.Two hundred twelve consecutive femoral neck fractures were treated with hip hemiarthroplasties with a minimum of 1 year of follow-up.All study patients were treated with a hip hemiarthroplasty and weight-bearing as tolerated postoperative day 1. Patients were prescribed daily physical therapy with the goal of mobilization before discharge from hospital.Mortality at 1 year; hospital readmission within 90 days.Two hundred twelve patients were included in the study. One-year mortality was 29%. One hundred thirty-two (62%) patients were able to ambulate before hospital discharge. Ambulation with physical therapy before discharge from hospital was a significant predictor of 1-year mortality when compared with patients who were unable to ambulate (hazard ratio 0.57; 95% confidence interval, 0.34-0.94; P = 0.03), which equates to 43% reduction in risk of mortality. There was no difference in the 90-day readmission rates for ambulatory versus nonambulatory patients.Ambulation with physical therapy before discharge reduced the risk of 1-year mortality by 43%, without an effect on 90-day readmission. Sixty-two percentage of our cohort was able to ambulate before discharge. Future investigations are warranted to further identify those patients at heightened risk of mortality and readmission and the role of early rehabilitation in recovery.Prognostic Level III.

OBJECTIVE To identify the patient, injury and treatment factors associated with an acute infection during the treatment of open ankle fractures in a large multi-center retrospective review. To evaluate the effect of infectious complications on the rates of nonunion, malunion, and loss of reduction. DESIGN Multi-center Retrospective Review. SETTING Sixteen Trauma Centers. PATIENTS One thousand and three consecutive skeletally mature patients (514 men and 489 women) with open ankle fractures. MAIN OUTCOME MEASURES Fracture-related infection (FRI) in open ankle fractures. RESULTS The charts of 1,003 consecutive patients were reviewed and 712 patients (357 women and 355 men) had at least 12 weeks of clinical follow-up. Their average age was 50 years (range 16-96), and average BMI was 31; they sustained OTA/AO types 44A (12%), 44B (58%), and 44C (30%) open ankle fractures. The rate FRI rate was 15%. A multivariable regression analysis identified male sex, diabetes, smoking, immunosuppressant use, time to wound closure, and wound location as independent risk factors for infection. There were 77 cases of malunion, nonunion, loss of reduction and/or implant failure; FRI was associated with higher rates of these complications (p=0.01). CONCLUSION Several patient, injury and surgical factors were associated with fracture-related infection in the treatment of open ankle fractures. LEVEL OF EVIDENCE Prognostic Level IV.

OBJECTIVE To compare immediate quality of open reduction of femoral neck fractures by alternative surgical approaches. DESIGN Retrospective cohort study. SETTING Twelve Level 1 North American trauma centers. PATIENTS Eighty adults 18-65 years of age with isolated, displaced, OTA/AO type 31-B2 or -B3 femoral neck fractures treated with internal fixation. INTERVENTION Thirty-two modified Smith-Petersen anterior approaches versus 48 Watson-Jones anterolateral approaches for open reduction performed by fellowship-trained orthopaedic trauma surgeons. MAIN OUTCOME Reduction quality as assessed by 3 senior orthopaedic traumatologists as "acceptable" or "unacceptable" on AP and lateral postoperative radiographs. RESULTS No difference was observed in the rate of acceptable reduction by modified Smith-Petersen (81%) versus Watson-Jones (81%) approach (risk difference null, 95% confidence interval -17.4% to 17.4%, P = 1.00) with 90.4% panel agreement (Fleiss' weighted κ = 0.63, P < 0.01). Stratified analyses did not identify a significant difference in the rate of acceptable reduction between approaches when stratified by Pauwels angle, basicervical or transcervical fracture location, or posterior comminution. The Smith-Petersen approach afforded a better reduction when preoperative skeletal traction was not applied (RR = 1.67 [95% CI 1.10-2.52] vs. RR = 0.87 [95% CI 0.70-1.08], P = 0.006). CONCLUSIONS No difference was observed in the quality of open reduction of displaced femoral neck fractures in young adults when a Watson-Jones anterolateral approach versus a modified Smith-Petersen anterior approach was performed by orthopaedic trauma surgeons.

Objectives To evaluate a large series of open fractures of the forearm following gunshot wounds in order to determine complication rates and factors that may lead to infection, nonunion, or compartment syndrome. Design Multi-center retrospective review. Setting Nine Level 1 Trauma CentersPatients/Participants: 168 patients had 198 radius and ulna fractures due to firearm injuries. All patients were adults, had a fracture due to a firearm injury and at least one year clinical follow-up or follow-up until union. Average follow-up was 831 days. Intervention Most patients (91%) received antibiotics. Formal irrigation and debridement in the operating room was performed in 75% of cases along with either internal fixation (75%), external fixation (6%), or I&D without fixation (19%). Main outcome measures Complications including neurovascular injuries, compartment syndrome, infection and nonunion. Results Twenty-one percent of patients had arterial injuries and 40% had nerve injuries. Nine patients (5%) developed compartment syndrome. Seventeen patients (10%) developed infections, all in comminuted or segmental fractures. Antibiotics were not associated with a decreased risk of infection. Infections in the ulna were more common in fractures with retained bullet fragments and bone loss. Twenty patients (12%) developed a nonunion. Nonunions were associated with high velocity firearms and bone defect size. Conclusions Open fractures of the forearm from gunshot wounds are serious injuries that carry high rates of nonunion and infection. Fractures with significant bone defects are at increased risk of nonunion and should be treated with stable fixation and proper soft tissue handling. Ulna fractures are at particularly high risk for deep infection and septic nonunion and should be treated aggressively. Forearm fractures from gunshot wounds should be followed until union to identify long term complications. Level of evidence Prognostic Level III.

Objective To evaluate rates of complications in patients with bilateral femur fractures treated with intramedullary nailing (IMN) during either 1 single procedure or 2 separate procedures. Design A multicenter retrospective review of patients sustaining bilateral femur fractures, treated with IMN in single or 2-stage procedure, from 1998 to 2018 was performed at 10 Level-1 trauma centers. Setting Ten Level-1 trauma centers. Patients/participants Two hundred forty-six patients with bilateral femur fractures. Interventions Intramedullary nailing. Main outcome measures Incidence of complications. Results A total of 246 patients were included, with 188 single-stage and 58 two-stage patients. Gender, age, injury severity score, abbreviated injury score, secondary injuries, Glasgow coma scale, and proportion of open fractures were similar between both groups. Acute respiratory distress syndrome (ARDS) occurred at higher rates in the 2-stage group (13.8% vs. 5.9%; P value = 0.05). When further adjusted for age, gender, injury severity score, abbreviated injury score, Glasgow coma scale, and admission lactate, the single-stage group had a 78% reduced risk for ARDS. In-hospital mortality was higher in the single-stage cohort (2.7% compared with 0%), although this did not meet statistical significance (P = 0.22). Conclusions This is the largest multicenter study to date evaluating the outcomes between single- and 2-stage IMN fixation for bilateral femoral shaft fractures. Single-stage bilateral femur IMN may decrease rates of ARDS in polytrauma patients who are able to undergo simultaneous definitive fixation. However, a future prospective study with standardized protocols in place will be required to discern whether single- versus 2-stage fixation has an effect on mortality and to identify those individuals at risk.

Objective To evaluate the clinical and patient-reported outcomes of patients with femoral head fractures treated at a single level I trauma center with a minimum 10-year follow-up. Design Retrospective review SETTING:: Academic Level-1 Trauma Center PATIENTS/PARTICIPANTS:: One hundred and one consecutive femoral head fractures were identified for this study. The final study group consisted of 28 patients with a minimum of 10-years of clinical follow-up. Intervention All patients were treated with one or in combination with the following treatments: nonoperative management, open reduction and internal fixation, fragment excision, or total hip arthroplasty. Main outcome measures Oxford Hip Score at final follow-up along with clinical and radiological complications; infection, avascular necrosis, post-traumatic osteoarthritis, heterotopic ossification, and conversion to total hip arthroplasty. Results Twenty-eight patients with greater than 10 years of follow-up were included in this evaluation. The average follow-up was 14 years and the average age was 39.2 years. Surgical management occurred in 86% of patients, and the mean time to definitive treatment was 3.7 days. Overall, 21 patients (75%) experienced a complication. Seven patients (30%) were later converted to a total hip arthroplasty (THA) at an average of 6.4 years from initial injury. Three of the seven late THA conversions (43%) required later revision. Oxford hip scores (OHS) were obtained in all 28 patients at final follow-up. The average OHS was 36.6. The mean OHS of the native hips was 37 at an average follow-up of 13.6 years. The mean OHS of primary THA was 41 and the mean OHS of secondary THA at final follow-up was 31.4, but this was not statistically significant (p = .134). Conclusions Patients should be counseled that the long-term results of open reduction and internal fixation may be satisfactory but unfortunately are not predictable.

Objectives To determine the radial nerve palsy (RNP) rate and predictors of injury after humeral nonunion repair in a large multicenter sample. Design Consecutive retrospective cohort review. Setting Eighteen academic orthopedic trauma centers. Patients/participants Three hundred seventy-nine adult patients who underwent humeral shaft nonunion repair. Exclusion criteria were pathologic fracture and complete motor RNP before nonunion surgery. Intervention Humeral shaft nonunion repair and assessment of postoperative radial nerve function. Main outcome Measurements: Demographics, nonunion characteristics, preoperative and postoperative radial nerve function and recovery. Results Twenty-six (6.9%) of 379 patients (151 M, 228 F, ages 18-93 years) had worse radial nerve function after nonunion repair. This did not differ by surgical approach. Only location in the middle third of the humerus correlated with RNP (P = 0.02). A total of 15.8% of patients with iatrogenic nerve injury followed for a minimum of 12 months did not resolve. For those who recovered, resolution averaged 5.4 months. On average, partial/complete palsies resolved at 2.6 and 6.5 months, respectively. Sixty-one percent (20/33) of patients who presented with nerve injury before their nonunion surgery resolved. Conclusion In a large series of patients treated operatively for humeral shaft nonunion, the RNP rate was 6.9%. Among patients with postoperative iatrogenic RNP, the rate of persistent RNP was 15.8%. This finding is more generalizable than previous reports. Midshaft fractures were associated with palsy, while surgical approach was not. Level of evidence Therapeutic Level IV.

Objectives To determine (1) which factors are associated with the choice to perform an open reduction and (2) by adjusting for these factors, if the choice of reduction method is associated with reoperation. Design Retrospective cohort study with radiograph and chart review. Setting Twelve Level 1 North American trauma centers. Patients Two hundred thirty-four adults 18-65 years of age with an isolated, displaced, OTA/AO type 31-B2 or type 31-B3 femoral neck fracture treated with internal fixation with minimum of 6-month follow-up or reoperation. Exclusion criteria were pathologic fractures, associated femoral head or shaft fractures, and primary arthroplasty. Intervention Open or closed reduction technique during internal fixation. Main outcome Cox proportional hazard of reoperation adjusting for propensity score for open reduction based on injury, demographic, and medical factors. Reduction quality was assessed by 3 senior orthopaedic traumatologists as "acceptable" or "unacceptable" on AP and lateral postoperative radiographs. Results Median follow-up was 1.5 years. One hundred six (45%) patients underwent open reduction. Reduction quality was not significantly affected by open versus closed approach (71% vs. 69% acceptable, P = 0.378). The propensity to receive an open reduction was associated with study center; younger age; male sex; no history of injection drug use, osteoporosis, or cerebrovascular disease; transcervical fracture location; posterior fracture comminution; and surgery within 12 hours. A total of 35 (33%) versus 28 (22%) reoperations occurred after open versus closed reduction (P = 0.056). Open reduction was associated with a 2.4-fold greater propensity-adjusted hazard of reoperation (95% confidence interval 1.3-4.4, P = 0.004). A total of 35 (15%) patients underwent subsequent total hip arthroplasty or hemiarthroplasty. Conclusions Open reduction of displaced femoral neck fractures in nonelderly adults is associated with a greater hazard of reoperation without significantly improving reduction. Prospective randomized trials are indicated to confirm a causative effect of open versus closed reduction on outcomes after femoral neck fracture. Level of evidence Therapeutic Level III.

Objectives We conducted a large, U.S wide, observational study of type III tibial fractures, with the hypothesis that delays between definitive fixation and flap coverage might be a substantial modifiable risk factor associated with nosocomial wound infection. Design A retrospective analysis of a multicenter database of open tibial fractures requiring flap coverage. Setting Fourteen level-1 trauma centers across the United States. Patients Two hundred ninety-six (n = 296) consecutive patients with Gustilo III open tibial fractures requiring flap coverage at 14 trauma centers were retrospectively analyzed from a large orthopaedic trauma registry. We collected demographics and the details of surgical care. We investigated the patient, and treatment factors leading to infection, including the time from various points in care to the time of soft-tissue coverage. Intervention Delay definitive fixation and flap coverage in tibial type III fractures. Main outcome measurements (1) Results of multivariate regression with time from injury to coverage, debridement to coverage, and definitive fixation to coverage in the model, to determine which delay measurement was most associated with infection. (2) A second multivariate model, including other factors in addition to measures of flap delay, to provide the estimate between delay and infection after adjustment for confounding. Results Of 296 adults (227 M: 69 F) with open Gustilo type III tibial fractures requiring flap coverage, 96 (32.4%) became infected. In the multivariate regression, the time from definitive fixation to flap coverage was most predictive of subsequent wound infection (odds ratio 1.04, 95% confidence interval 1.01 to 1.08, n = 260, P = 0.02) among the time measurements. Temporary internal fixation was not associated with an increased risk of infection in both univariate (P = 0.59) or multivariate analyses (P = 0.60). Flap failure was associated with the highest odds of infection (odds ratio 6.83, 95% confidence interval 3.26 to 14.27, P Conclusion Orthoplastic teams that are dedicated to severe musculoskeletal trauma, that facilitate coordination of definitive fixation and flap coverage, will reduce the infection rates in Gustilo type III tibial fractures.

Objective To compare the volar Henry and dorsal Thompson approaches with respect to outcomes and complications for proximal third radial shaft fractures. Design Multicenter retrospective cohort study. Patients/participants Patients with proximal third radial shaft fractures ± associated ulna fractures (OTA/AO 2R1 ± 2U1) treated operatively at 11 trauma centers were included. Intervention Patient demographics and injury, fracture, and surgical data were recorded. Final range of motion and complications of infection, neurologic injury, compartment syndrome, and malunion/nonunion were compared for volar versus dorsal approaches. Main outcome The main outcome was difference in complications between patients treated with volar versus dorsal approach. Results At an average follow-up of 292 days, 202 patients (range, 18-84 years) with proximal third radial shaft fractures were followed through union or nonunion. One hundred fifty-five patients were fixed via volar and 47 via dorsal approach. Patients treated via dorsal approach had fractures that were on average 16 mm more proximal than those approached volarly, which did not translate to more screw fixation proximal to the fracture. Complications occurred in 11% of volar and 21% of dorsal approaches with no statistical difference. Conclusions There was no statistical difference in complication rates between volar and dorsal approaches. Specifically, fixation to the level of the tuberosity is safely accomplished via the volar approach. This series demonstrates the safety of the volar Henry approach for proximal third radial shaft fractures. Level of evidence Therapeutic Level III.

BACKGROUND Rising health care expenditures and declining reimbursements have generated interest in providing interventions of value. The use of external fixation is a commonly used intermediate procedure for the staged treatment of unstable fractures. External fixator constructs can vary in design and costs based on selected component configuration. The objective of this study was to evaluate cost variation and relationships to injury and noninjury characteristics in temporizing external fixation of tibial plateau fractures. We hypothesize that construct costs are highly variable and present no noticeable patterns with both injury and noninjury characteristics. METHODS A retrospective review of tibial plateau fractures treated with initial temporizing external fixation between 2010 and 2016 at 2 Level I trauma centers was conducted. Fracture and patient characteristics including age, body mass index, AO/OTA classification, and Schatzker fracture classification were observed with construct cost. In addition, injury-independent characteristics of surgeon education, site of procedure, and date of procedure were evaluated with construct cost. Factors associated with cost variation were assessed using nonparametric comparative and goodness-of-fit regression tests. RESULTS Two hundred twenty-one patient cases were reviewed. The mean knee spanning fixator construct cost was $4947 (95% confidence interval = $4742-$5152). The overall range in construct costs was from $1848 to $11,568. The mean duration of use was 16.4 days. No strong correlations were noted between construct cost and patient demographics (r = 0.02), fracture characteristics (r = 0.02), or injury-independent characteristics (r = 0.10). Finally, there was no significant difference between constructs of traumatologists and other orthopaedic surgeon subspecialists (P = 0.12). CONCLUSIONS Temporizing external fixation of tibial plateau is a high-cost intervention per unit of time and exhibits massive variation in the mean cost. This presents an ideal opportunity for cost savings by reducing excessive variation in implant component selection. LEVEL OF EVIDENCE Level III. Retrospective Cohort.

© 2017 Elsevier Ltd Background Reoperation rates are high after surgery for hip fractures. We investigated the effect of a sliding hip screw versus cancellous screws on the risk of reoperation and other key outcomes. Methods For this international, multicentre, allocation concealed randomised controlled trial, we enrolled patients aged 50 years or older with a low-energy hip fracture requiring fracture fixation from 81 clinical centres in eight countries. Patients were assigned by minimisation with a centralised computer system to receive a single large-diameter screw with a side-plate (sliding hip screw) or the present standard of care, multiple small-diameter cancellous screws. Surgeons and patients were not blinded but the data analyst, while doing the analyses, remained blinded to treatment groups. The primary outcome was hip reoperation within 24 months after initial surgery to promote fracture healing, relieve pain, treat infection, or improve function. Analyses followed the intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT00761813. Findings Between March 3, 2008, and March 31, 2014, we randomly assigned 1108 patients to receive a sliding hip screw (n=557) or cancellous screws (n=551). Reoperations within 24 months did not differ by type of surgical fixation in those included in the primary analysis: 107 (20%) of 542 patients in the sliding hip screw group versus 117 (22%) of 537 patients in the cancellous screws group (hazard ratio [HR] 0·83, 95% CI 0·63–1·09; p=0·18). Avascular necrosis was more common in the sliding hip screw group than in the cancellous screws group (50 patients [9%] vs 28 patients [5%]; HR 1·91, 1·06–3·44; p=0·0319). However, no significant difference was found between the number of medically related adverse events between groups (p=0·82; appendix); these events included pulmonary embolism (two patients [

Lessons learned from battle have been fundamental to advancing the care of injuries that occur in civilian life. Equally important is the need to further refine these advances in civilian practice, so they are available during future conflicts. The Major Extremity Trauma Research Consortium (METRC) was established to address these needs.METRC is a network of 22 core level I civilian trauma centers and 4 core military treatment centers-with the ability to expand patient recruitment to more than 30 additional satellite trauma centers for the purpose of conducting multicenter research studies relevant to the treatment and outcomes of orthopaedic trauma sustained in the military. Early measures of success of the Consortium pertain to building of an infrastructure to support the network, managing the regulatory process, and enrolling and following patients in multiple studies.METRC has been successful in maintaining the engagement of several leading, high volume, level I trauma centers that form the core of METRC; together they operatively manage 15,432 major fractures annually. METRC is currently funded to conduct 18 prospective studies that address 6 priority areas. The design and implementation of these studies are managed through a single coordinating center. As of December 1, 2015, a total of 4560 participants have been enrolled.Success of METRC to date confirms the potential for civilian and military trauma centers to collaborate on critical research issues and leverage the strength that comes from engaging patients and providers from across multiple centers.

Item does not contain fulltext BACKGROUND: The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) has been extensively evaluated in groups of patients with osteoarthritis, yet not in patients with a femoral neck fracture. This study aimed to determine the reliability, construct validity, and responsiveness of the WOMAC compared with the Short Form-12 (SF-12) and the EuroQol 5D (EQ-5D) questionnaires for the assessment of elderly patients with a femoral neck fracture. METHODS: Reliability was tested by assessing the Cronbach alpha. Construct validity was determined with the Pearson correlation coefficient. Change scores were calculated from ten weeks to twelve months of follow-up. Standardized response means and floor and ceiling effects were determined. Analyses were performed to compare the results for patients less than eighty years old with those for patients eighty years of age or older. RESULTS: The mean WOMAC total score was 89 points before the fracture in the younger patients and increased from 70 points at ten weeks to 81 points at two years postoperatively. In the older age group, these scores were 86, 75, and 78 points. The mean WOMAC pain scores before the fracture and at ten weeks and two years postoperatively were 92, 76, and 87 points, respectively, in the younger age group and 92, 84, and 93 points in the older age group. Function scores were 89, 68, and 79 points for the younger age group and 84, 71, and 73 points for the older age group. The Cronbach alpha for pain, stiffness, function, and the total scale ranged from 0.83 to 0.98 for the younger age group and from 0.79 to 0.97 for the older age group. Construct validity was good, with 82% and 79% of predefined hypotheses confirmed in the younger and older age groups, respectively. Responsiveness was moderate. No floor effects were found. Moderate to large ceiling effects were found for pain and stiffness scales at ten weeks and twelve months in younger patients (18% to 36%) and in the older age group (38% to 53%). CONCLUSIONS: The WOMAC showed good reliability, construct validity, and responsiveness in both age groups of elderly patients with a femoral neck fracture who had been physically and mentally fit before the fracture. The instrument is suitable for use in future clinical studies in these populations. CLINICAL RELEVANCE: The results are based on two clinical trials. The questionnaires used concern pure, clinically relevant issues (ability to walk, climb stairs, etc.). Moreover, the results can be used for future research comparing clinical outcomes (or treatments) for populations with a femoral neck fracture.

The purpose of this study is to characterize the presentation, size, treatment, and complications of pulmonary embolism (PE) in a large series of orthopaedic trauma patients who developed PE after injury.We reviewed the records of orthopaedic trauma patients who developed a PE within 6 months of injury at 9 trauma centers and 2 tertiary care facilities.There were 312 patients, 186 men and 126 women, average age 58 years. Average body mass index was 29.6, and average Injury Severity Score was 18. Seventeen percent received anticoagulation before injury, and 5% had a history of PE. After injury, 87% were placed on prophylactic anticoagulation and 68% with low-molecular weight heparin. Fifty-three percent of patients exhibited shortness of breath or chest pain. Average heart rate and O2 saturation before PE diagnosis were 110 and 94%, respectively. Thirty-nine percent had abnormal arterial blood gas, and 30% had abnormal electrocardiogram findings. Eighty-nine percent had computed tomography pulmonary angiography for diagnosis. Most clots were segmental (63%), followed by subsegmental (21%), lobar (9%), and central (7%). The most common treatment was unfractionated heparin and Coumadin (25%). Complications of anticoagulation were common: 10% had bleeding at the surgical site. Other complications of anticoagulation included gastrointestinal bleed, anemia, wound complications, death, and compartment syndrome. PE recurred in 1% of patients. Four percent died of PE within 6 months.This is the first large data set to evaluate the course of PE in an orthopaedic trauma population. The complications of anticoagulation are significant and were as common in patients with lower risk clots as those with higher risk clots.
