Objectives: To explore the utility of legacy demographic factors and ballistic injury mechanism relative to popular markers of socioeconomic status as prognostic indicators of 10-year mortality following hospital discharge in a young, healthy patient population with isolated orthopedic trauma injuries., Methods: A retrospective cohort study was performed to evaluate patients treated at an urban Level I trauma center from January 1, 2003, through December 31, 2016. Current Procedure Terminology (CPT) codes were used to identify upper and lower extremity fracture patients undergoing operative fixation. Exclusion criteria were selected to yield a patient population of isolated extremity trauma in young, otherwise healthy individuals between the ages of 18 and 65 years. Variables collected included injury mechanism, age, race, gender, behavior risk factors, Area Deprivation Index (ADI), and insurance status. The primary outcome was post-discharge mortality, occurring at any point during the study period., Results: We identified 2539 patients with operatively treated isolated extremity fractures. The lowest two quartiles of socioeconomic status (SES) were associated with higher hazard of mortality than the highest SES quartile in multivariable analysis (Quartile 3 HR: 2.2, 95% CI: 1.2-4.1, p = 0.01; Quartile 4 HR: 2.2, 95% CI: 1.1-4.3, p = 0.02). Not having private insurance was associated with higher mortality hazard in multivariable analysis (HR 2.0, 95% CI: 1.3-3.2, p = 0.002). The presence of any behavioral risk factor was associated with higher mortality hazard in univariable analysis (HR: 1.8, p < 0.05), but this difference did not reach statistical significance in multivariable analysis (HR: 1.4, 95%: 0.8-2.3, p = 0.20). Injury mechanism (ballistic versus blunt), gender, and race were not associated with increased hazard of mortality (p > 0.20)., Conclusion: Low SES is associated with a greater hazard of long-term mortality than ballistic injury mechanism, race, gender, and medically diagnosable behavioral risk factors in a young, healthy orthopedic trauma population with isolated extremity injury., Competing Interests: Declaration of Competing Interest N.

The aim of this study was to develop and validate risk prediction models for deep surgical site infection (SSI) caused by specific bacterial pathogens after fracture fixation. A retrospective case-control study was conducted at a level I trauma center. Fifteen candidate predictors of the bacterial pathogens in deep SSI were evaluated to develop models of bacterial risk. The study included 441 patients with orthopedic trauma with deep SSI after fracture fixation and 576 control patients. The main outcome measurement was deep SSI cultures positive for methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S aureus (MRSA), gram-negative rods (GNRs), anaerobes, or polymicrobial infection within 1 year of injury. Prognostic models were developed for five bacterial pathogen outcomes. Mean area under the curve ranged from 0.70 (GNRs) to 0.74 (polymicrobial). Strong predictors of MRSA were American Society of Anesthesiologists (ASA) classification of III or greater (odds ratio [OR], 3.4; 95% CI, 1.6-8.0) and time to fixation greater than 7 days (OR, 3.4; 95% CI, 1.9-5.9). Gustilo type III fracture was the strongest predictor of MSSA (OR, 2.5; 95% CI, 1.6-3.9) and GNRs (OR, 3.4; 95% CI, 2.3-5.0). ASA classification of III or greater was the strongest predictor of polymicrobial infection (OR, 5.9; 95% CI, 2.7-15.5) and was associated with increased odds of GNRs (OR, 2.7; 95% CI, 1.5-5.5). Our models predict the risk of MRSA, MSSA, GNR, anaerobe, and polymicrobial infections in patients with fractures. The models might allow for modification of preoperative antibiotic selection based on the particular pathogen posing greatest risk for this patient population. [ Orthopedics . 2024;47(1):e19-e25.].

Objective: To determine the effectiveness of vancomycin powder in preventing infection after plate and screw fixation of tibial plateau fractures considered at low risk of infection., Design: Retrospective cohort study., Setting: Single, Level I trauma center., Patients/participants: This study included 459 patients with tibial plateau fractures (OTA/AO 41-B/C) who underwent open reduction and internal fixation from 2006 to 2018 and were considered at low risk of infection based on not meeting the "high risk" definition of the VANCO trial., Intervention: Vancomycin powder administration on wound closure at the time of definitive fixation., Main Outcome Measurements: Deep surgical site infection with at least 1 gram-positive bacteria culture., Results: Vancomycin powder administration was associated with reduction in gram-positive infection from 4% to 0% (odds ratio, 0.12; 95% confidence interval, 0.04-0.32; P < 0.01). No significant effect was reported in gram-negative only infections, which were observed in 0.3% in the control group, compared with 0.9% in the intervention group (odds ratio, 2.71; 95% confidence interval, 0.11-69; P = 0.54). Methicillin-resistant Staphylococcus aureus was the most common organism isolated in the control group, growing in 9 of 18 infections (50%)., Conclusions: Among patients with low-risk tibial plateau fractures, vancomycin powder at the time of definitive fixation showed a reduction in the incidence of gram-positive deep surgical site infection. The observed relative effect was relatively larger than that observed in a previous randomized trial on high-risk fractures. These data might support broadening the indication for use of vancomycin powder to include tibial plateau fractures at low risk of infection., Level of Evidence: Therapeutic Level III.

Background: To determine if the use of a narrower elastic tourniquet compared to a standard pneumatic tourniquet reduces operative blood loss in the operative fixation of humeral shaft fractures., Methods: This retrospective cohort study was performed at a level I trauma center and included 134 patients, aged 18 to 90 years, with a humeral shaft fracture treated with open reduction internal fixation (ORIF) from January 2007 through June 2018. The primary variable of interest was the application of a HemaClear™ elastic tourniquet versus a standard pneumatic tourniquet during the fixation of a humeral shaft fracture. The primary outcome was estimated blood loss (EBL) during the humerus ORIF surgery as recorded in the operative record. The secondary outcomes were total tourniquet time and operative time. The primary purpose of the study was to compare the above outcomes between the two tourniquet types., Results: Estimated blood loss was 42% lower (95% CI: 11% to 73%, p < 0.01) in the elastic tourniquet group when compared to the standard pneumatic tourniquet group. The use of the elastic tourniquet was also associated with a 67% increase (95% CI: 35% to 100%, p < 0.01) in tourniquet time compared to the standard pneumatic tourniquet. No difference in the total operative time between the two groups (difference, -3%; 95% CI: -21 to 14, p = 0.72) was observed., Conclusion: Elastic tourniquet use was associated with 42% less blood loss in the fixation of humeral shaft fractures compared to use of a traditional pneumatic tourniquet, although this may be of unclear clinical importance given the relatively low estimated blood loss in this cohort. The potential benefit of reduced blood loss associated with the narrower elastic tourniquet is likely caused by the increased tourniquet time, without a change in overall operative time., Competing Interests: Declaration of interests C.

Objectives: Operative management of acetabular fractures is technically challenging, but there is little data regarding how surgeon experience affects outcomes. Previous efforts have focused only on reduction quality in a single surgeon series. We hypothesized that increasing surgeon experience would be associated with improved acetabular surgical outcomes in general., Design: Retrospective cohort study., Setting: Urban academic level-I trauma center., Patients/participants: Seven hundred ninety-five patients who underwent an open reduction internal fixation for an acetabular fracture., Results: There was a significant association between surgeon experience and certain outcomes, specifically reoperation rate (16.9% overall), readmission rate (13.9% overall), and reduction quality. Deep infection rate (9.7% overall) and secondary displacement rate (3.7% overall) were not found to have a significant association with surgeon experience. For reoperation rate, the time until 50% peak performance was 2.4 years in practice., Conclusion: Surgeon experience had a significant association with reoperation rate, quality of reduction, and readmission rate after open reduction internal fixation of acetabular fractures. Other patient outcomes were not found to be associated with surgeon experience., Level of Evidence: Prognostic Level III.

Background: Recently social media use within healthcare has increased significantly. Today, it is common for patients to browse the Internet, including physicians' social media pages, to learn about their medical conditions and search for providers. The purpose of this study is to analyze the use of social media among hand surgeons, and to compare this use between academic and private surgeons., Methods: Using the American Society for Surgery of the Hand's (ASSH) online directory, all active members practicing within the ten most populated U.S. cities were identified. Social media presence was determined by an Internet search of platforms. Members were stratified by practice model (academic vs. private). Chi-square and t-tests were used to compare categorical and continuous variables, and a multivariable logistic regression was performed for the binary variable practice model., Results: Two hundred and fifty-six hand surgeons were identified with 150 (59%) in academic and 106 (41%) in private practice. For ResearchGate accounts, 51 (82%) were academic and 11 (18%) were private. Mean PubMed publications was 38 for academic and 9 for private. YouTube presence was 69 (70%) in academic and 29 (30%) in private. On multivariable analysis, the odds of having ResearchGate and YouTube presence were higher for academic practice. There was no statistically significant difference by practice type for Facebook, Twitter, LinkedIn, and Instagram., Conclusions: With the recent social media expansion, surgeons have adopted social media platforms to reach patients. While the literature has shown that private practices are more active in social media, our results show they are not more active than academic practices in the ten most populated U.S. cities., Level of Evidence: IV., Competing Interests: The authors have no conflict of interests to disclose

Objective: To quantify patient preferences towards time to return to driving relative to compromised reaction time and potential complication risks., Design: Cross-sectional discrete choice experiment., Setting: Academic trauma center., Patients: Ninety-six adult patients with an operative lower extremity fracture from December 2019 through December 2020., Intervention: None., Main Outcome Measurement: Patient completed a discrete choice experiment survey consisting of 12 hypothetical return to driving scenarios with varied attributes: time to return to driving (range: 1 to 6 months), risk of implant failure (range: 1% to 12%), pain upon driving return (range: none to severe), and driving safety measured by braking distance (range: 0 to 40 feet at 60 mph). The relative importance of each attribute is reported on a scale of 0% to 100%., Results: Patients most valued a reduced pain level when resuming driving (62%), followed by the risk of implant failure (17%), time to return to driving (13%), and braking safety (8%). Patients were indifferent to returning to driving at 1 month (median utility: 28, interquartile range [IQR] -31 to 80) or 2 months (median utility: 59, IQR: 41 to 91) postinjury., Conclusion: Patients with lower extremity injuries demonstrated a willingness to forego earlier return to driving if it might mean a decrease in their pain level. Patients are least concerned about their driving safety, instead placing higher value on their own pain level and chance of implant failure. The findings of this study are the first to rigorously quantify patient preferences toward a return to driving and heterogeneity in patient preferences., Level of Evidence: V., Competing Interests: The remaining authors have no conflicts of interest to disclose., (Copyright © 2022 The Authors.

Objectives: To determine if changes in pelvic trauma care and treatment protocols have affected overall mortality rates after pelvic ring injury., Design: Retrospective cohort study., Setting: Level I trauma center., Patients/participants: A total of 3314 patients with pelvic ring injuries who presented to a single referral center from 1999 to 2018 were included in the study., Intervention: Pelvic ring management, years 1999-2006 versus years 2007-2018., Main Outcome Measurements: In hospital mortality. Other examined variables included change in patient demographics, fracture characteristics, date of injury, associated injuries, length of hospital stay, Abbreviated Injury Severity Score., Results: The composite mortality rate was 6.5% (214/3314). The earliest cohort presented a mortality rate of 9.1% [111/1224; 95% confidence interval (CI), 7.6%-10.8%] compared with the more recent cohort mortality rate of 4.9% (103/2090; 95% CI, 4.1%-5.9%). Overall mortality was significantly lower in the more recent period, a risk difference of 4.1% (95% CI, 2.3%-6.1%; P < 0.01). After adjusting for age and Abbreviated Injury Severity Score of the brain, chest, and abdomen, the mortality reduction was more pronounced with an adjusted risk difference of 6.4% (95% CI, 4.7%-8.1%; P < 0.01)., Conclusion: Significant improvement in the mortality rate of pelvic ring injuries has been demonstrated in recent years (4.9% vs. 9.1%) and the difference is even large when accounting for known confounders. Improvement appears to coincide chronologically with changes in trauma resuscitation and implementation of adjuvant treatments for managing patients with severe hemorrhagic shock. Although the exact benefit of each treatment awaits further research, these data might indicate improved care over time for these difficult patients., Level of Evidence: Therapeutic Level III.

Objective: To evaluate the outcomes of patients with pelvic ring injuries managed with resuscitative endovascular balloon occlusion of the aorta (REBOA)., Design: Retrospective case series., Setting: Academic, Level 1 trauma center in North America., Patients: Twenty-five patients with disruption of the pelvic ring and hemodynamic instability., Intervention: Placement of a REBOA device as an adjuvant treatment to trauma resuscitation., Main Outcome Measure: Death and ischemic-related complications., Results: The average age of patients was 43 years (range: 17-85). Patients presented with a median lactate of 6.3 mmol/L, systolic blood pressure of 116 mm Hg, heart rate of 121 beats/minute, and injury severity score of 34. The median unit of packed red blood cells received through transfusion in the first 24 hours of hospital admission was 13 (interquartile range: 8-28). Young-Burgess injury patterns included fractures of the following types: 5 lateral compression (LC)-1, 1 LC-2, 8 LC-3, 4 anteroposterior compression-2, and 7 anteroposterior compression-3. Angiography and embolization were performed in 24 (96%) patients. Selective embolization occurred in 18 (72%) patients, with nonselective angiography of the iliac system occurring in 7 (24%) patients. There were 12 (48%) deaths, 7 (28%) patients requiring lower extremity fasciotomy, and 5 (20%) patients requiring lower extremity amputations, and there was 1 (4%) patient requiring thrombectomy., Conclusions: REBOA use in pelvic ring injuries is rare and most frequently used in critically ill patients with polytrauma. Successful pelvic embolization can occur in concert with REBOA use; however, the severity of injury is associated with a high complication profile. In this series of 25 patients, in-hospital mortality was 48%. For those patients who survived, 54% experienced a major complication (fasciotomy, amputation, and deep infection). Further investigation is required to evaluate the role REBOA may play in managing these patients., Level of Evidence: Therapeutic Level IV.

Objectives: To determine the association between displaced femoral shaft bone fragments ("spikes") seen on radiographs after intramedullary nail insertion and the need for future motion surgery., Design: Retrospective case-control study., Setting: Academic trauma center., Patients: We included patients with femoral shaft fractures treated with intramedullary nail insertion. Case patients (n = 22) had developed knee stiffness treated with motion surgery. The control group was a randomly selected sample (1:3 ratio)., Main Outcome Measures: Motion surgery to address knee stiffness. We defined a "spike distance ratio" and "spike area ratio" from initial postoperative anteroposterior and lateral radiographs. Multivariable logistic regression determined the effect of spike distance and area ratios on the likelihood of need for motion surgery, controlling for polytraumatic injuries and bilateral fractures., Results: The case group had a median femoral spike distance ratio of 1.9 [interquartile range (IQR), 1.6-2.5] compared with 1.5 (IQR, 1.2-1.8) in the control group. An increased femoral spike distance ratio was associated with increased odds of motion surgery (P < 0.01). A femoral spike distance >2 times the femoral radius had 32 times the odds (95% confidence interval, 2-752) of motion surgery compared with patients with distance ratios <1.25. Median femoral spike area ratios were similar between the case (0.2; IQR, 0.1-0.5) and control (0.2; IQR, 0.0-0.5) groups and were not associated with increased odds of motion surgery (P = 0.34)., Conclusions: A larger spike distance ratio is associated with increased odds of subsequent motion surgery., Level of Evidence: Prognostic Level III.

Introduction: We assessed the outcome and safety of posterior plating of distal tibial fractures., Methods: We conducted a retrospective case series at a Level I trauma center. Seventy-four consecutive patients with distal tibial fractures treated with anatomically contoured 3.5-mm T-shaped locking compression plate using a posterolateral approach from January 2008 through April 2018 were included in the study. The mean patient age was 48 years (range, 18-87 years). Fifty-nine percent of the patients were male patients, 47% of the fractures were open fractures; and 27% of the patients had multiple traumatic injuries. Eleven fractures were AO/OTA type 42, 22 were type 43A, and 41 were type 43C. Sixty-two (84%) patients were treated with initial spanning external fixation (median time, 23 days) and staged open reduction and internal fixation. The main outcome measure was unplanned reoperation to address implant failure, nonunion, deep surgical site infection, or symptomatic implant., Results: Overall risk of unplanned reoperation was 15% (11 of 74 patients, 95% confidence interval, 9%-25%). Four (5%) reoperations were for nonunion, three (4%) were for surgical site infection, two (3%) were for infected nonunion, and two (3%) were for implant prominence. Loss of alignment >10 degrees occurred in one patient who underwent unplanned reoperation for nonunion. No plate breakage occurred. Median time to reoperation was 221 days (range, 22-436 days). Only one other complication was noted: wound dehiscence associated with the posterolateral approach, which was treated with irrigation and débridement and a 6-week regimen of oral antibiotics., Conclusions: Use of a posterolateral approach with a pre-contoured locking compression T-plate for the treatment of distal tibial fractures led to reasonable outcomes with an acceptable risk of unplanned reoperation, even with a high proportion of open fractures commonly staged with external fixation., Competing Interests: Declaration Competing of Interest We declare that we have no conflicts of interest., (Copyright © 2020.
