Pilon fractures often result from high energy mechanisms resulting in long-term morbidity and postoperative complications. While there is extensive literature investigating frailty scales as tools for preoperative risk stratification in orthopedic surgery, there is no literature regarding their use in fixation of pilon fractures. The objective of this study was to compare the predictive ability and discriminative accuracy of the Revised Risk Analysis Index (RAI-rev) and the 5-Item Modified Frailty (mFI-5) in 30-day postoperative outcomes following surgical fixation of pilon fractures. The ACS-NSQIP database was used to identify patients undergoing surgical fixation of pilon fractures from 2015 to 2020. Multivariate analysis was used to analyze the predictive ability of frailty status for 30-day postoperative outcomes. Discriminatory accuracy of frailty scales was assessed using receiver operating characteristic analysis. Significance was determined by p < 0.05. This study included 2935 patients, aged 33-59, of which 53 % (1562/2935) were male. The RAI-rev categorized 44.2 % (1296/2935) as normal, 44.6 % (1309/2935) as frail, and 11.2 % (330/2935) as severely frail. The mFI-5 was a significant predictor of major complications, readmission, and CDIV complications for severely frail patients and of eLOS, and NHD in both frail and severely frail patients. The RAI-rev had superior discriminative accuracy for most outcomes with good discriminative ability for NHD compared to mFI-5 (0.79 vs 0.74). This study demonstrated that compared to RAI-rev, mFI-5 is a significant predictor of postoperative complications after surgical fixation of pilon fractures, but RAI-rev had more accurate predictive ability when compared to mFI-5, most notable for NHD (AUC 0.79 vs 0.74). However, ROC values for both RAI (AUC 0.65-0.79) and mFI-5 (AUC 0.59-0.74) still fell below an AUC of 0.80 indicating that overall frailty is not a strong predictor of outcomes. These findings support the need for further research into preoperative risk assessment in pilon fracture patients. III - retrospective cohort study.

Introduction Pedestrian road injuries are a significant public health issue in Georgia, Syria, and Tajikistan. This study investigates the trends in mortality, Years of Life Lost (YLLs), and incidence rates of pedestrian road injuries from 1990 to 2021, with a focus on sex-specific differences, using age-standardized data from the Global Burden of Disease (GBD) database. Methods The data for this analysis were obtained from the GBD database, emphasizing age-standardized rates of mortality, YLLs, and incidence of pedestrian-related road injuries in Georgia, Syria, and Tajikistan. The population was divided into male and female cohorts for comparison. Statistical methods included descriptive statistics, independent samples t-tests, and effect size calculations to evaluate the differences between sexes. Temporal trends were analyzed to observe changes over the study period. Results Mortality The analysis revealed that males had a significantly higher mean mortality rate (7.18, SD = 2.94) compared to females (2.26, SD = 0.78). The independent samples t-test confirmed a significant difference (t(62) = 9.141, p < 0.001). The effect sizes were substantial, with Cohen's d at 2.285, Hedges' g at 2.257, and Glass's Δ at 6.281. Over time, the mortality rates exhibited peaks in the early 1990s and mid-2000s, with a general decline afterward. Males consistently showed higher mortality rates than females throughout the period. YLLs (Years of Life Lost) For YLLs, males had a significantly higher mean rate (332.59, SD = 132.31) compared to females (103.35, SD = 32.57), with the t-test indicating a significant difference (t(62) = 9.515, p < 0.001). Effect sizes supported the significance of this difference, with Cohen's d at 2.379, Hedges' g at 2.350, and Glass's Δ at 7.308. The YLL rates showed notable peaks in the early 1990s and mid-2000s, followed by a decline, with males maintaining higher rates than females. Incidence Regarding incidence, males had a higher mean rate (235.90, SD = 36.09) compared to females (89.53, SD = 15.29). The t-test results (t(62) = 21.125, p < 0.001) and effect sizes (Cohen's d = 5.281, Hedges' g = 5.217, and Glass's Δ = 9.574) confirmed a significant difference between the sexes. Incidence rates demonstrated a significant decline from 1990 to 2000, followed by fluctuations, with males consistently experiencing higher rates than females. Conclusion This study underscores significant sex differences in mortality, YLLs, and incidence rates due to pedestrian road injuries in Georgia from 1990 to 2021, with males consistently showing higher rates. These findings emphasize the need for targeted interventions to address the specific vulnerabilities of male pedestrians in Georgia. The data and analysis were facilitated through collaboration with the Global Burden of Disease Study, whose contributions were invaluable.

Introduction: Soft tissue flaps are an integral and versatile tool to help manage soft tissue defects of varying severities. These complex procedures can be done by a variety of specialties and can lead to a variety of postoperative complications. Locoregional flaps are the middle rung of the reconstructive ladder and can be performed by surgeons of various training pathways. The profile of patients and their complications when stratified by surgical specialty is unknown. The purpose of this study was to compare short-term postoperative outcomes between surgical subspecialists performing a locoregional flap of the lower extremity to determine factors influencing complication rates. Methods: The National Surgical Quality Improvement Project (NSQIP) database was queried using Current Procedural Terminology code 15,738 to identify adult patients undergoing a muscle, myocutaneous, or fasciocutaneous lower extremity flap procedure from 2016 to 2019. We examined the primary outcome of a pooled wound complication rate with secondary outcomes including the individual NSQIP wound- and nonwound complications. Results: A total of 1324 patients were identified. Plastic surgeons performed 926 (70%) procedures, general surgeons performed 243 (18%) procedures, orthopedic surgeons performed 89 (7%) procedures, and vascular surgeons performed 66 (5%) procedures. On multivariate analysis, surgical subspecialty was not associated with the primary outcome, but malignancy-related operations and nonelective status were considered significant. Conclusions: Patient characteristics, but not surgeon subspecialty, account for the variation in patient outcomes in lower extremity flap reconstruction. Larger, prospective studies examining these outcomes are needed to further characterize complication risk factors in this patient population.
