Radial bowing is necessary for forearm rotation. Fractures or deformities of the that affect radial bow may disrupt normal The purpose this study was to evaluate development and establish normative values pediatric adolescent bow. A retrospective review radiographs from children aged 0-17 years with no previous history an upper extremity fracture condition performed. Patient demographics, maximal location, depth were recorded in millimeters as percentages total length. proximal, middle,...
Introduction: Traumatic lower extremity injuries can have devastating, long-lasting impacts on patients’ lives. However, it is not well understood how patient-reported outcomes (PROs) evolve following such injuries. We aimed to measure LIMB-Q scores in patients severe traumatic determine temporal trends PROs. Methods: performed a cross-sectional study of trauma with distal the mid-femur who required fracture management, limb salvage, and/or amputation. collected self-reported clinical and...
To identify modifiable and nonmodifiable risk factors for reoperation to promote union after distal femur fracture.Multicenter retrospective cohort study.Ten Level-I trauma centers.Patients with OTA/AO 33A or C fractures (n = 1111).Surgical fixation of fracture. Fixation constructs were classified as lateral plate, dual nail, nail plate combination.The outcome interest was unplanned union.There an 11% (121/1111) rate union. In the multivariate analysis, predictive included body mass index...

Setting: 3 US Level 1 trauma centers. Patient Selection Criteria: Adult survivors an treated between June 2016 through March 2023 were identified from institutional registries. The experiment was administered as a survey August 2023. Outcome Measures and Comparisons: Participants chose 12 hypothetical comparisons treatment...
To evaluate the presence of financial distress and identify risk factors for toxicity in patients after tibial shaft fracture.A cross-sectional analysis.Level I trauma center.All within 4 years fracture (open, closed, or that required flap reconstruction).Injury-related distress.Financial related to injury, as reported by patient a binary question. Financial using LIMB-Q, scored from 0 100, with higher scores indicating more toxicity.Data were collected 142 [44% closed (n = 62), 41% open...
To identify risk factors of reoperation to promote union or address deep surgical-site infection (DSSI) in periprosthetic distal femur fractures treated with lateral femoral locking plates (LDFLPs).
To identify potentially modifiable risk factors for deep surgical site infection after distal femur fracture.Multicenter retrospective cohort study.Ten Level-I trauma centers.Patients with OTA/AO 33A or C fractures (n = 1107).Surgical fixation of fracture.The outcome interest was infection.There a 7% rate (79/1107) infection. In the multivariate analysis, predictive included alcohol abuse [odds ratio (OR) 2.36; 95% confidence interval (CI), 1.17-4.46; P 0.01], intra-articular injury (OR...
To compare blood loss as estimated by surgeon-estimated (EBL), the Gross formula, and HB equation in open pelvic acetabular surgery.Retrospective cohort study.Single Level I academic trauma center.We included 710 patients 18-89 years of age who underwent or surgery between 2008 2018 for management fracture.Surgical treatment fracture transfusion when deemed clinically appropriate perioperative setting.Surgeon EBL calculated (using a formula derivative, with both Moore Nadler volume...
Abstract Objective: To identify technical factors associated with nonunion after operative treatment lateral locked plating. Design: Retrospective cohort study. Setting: Ten Level 1 trauma centers. Participants: Six hundred fifteen adult patients supracondylar distal femur fractures (OTA/AO Type 33A or C). Intervention: Lateral Main Outcome Measurements: Surgery for nonunion. Results: We observed rates of 2% in a low-risk group (n = 129), 4% medium-risk 333), and 14% high-risk 153). Varus...
Evaluate the species distribution and resistance patterns of bacterial pathogens causing surgical site infection (SSI) after operative fracture repair, with without use intrawound powdered antibiotic (IPA) prophylaxis during index surgery.
SUMMARY What is the nature of evolutionary divergence jaw skeleton within genus Oncorhynchus ? How can two associated bones evolve new shapes and still maintain functional integration? Here, we introduce test a “concordance” hypothesis, in which an extraordinary matching shape changes dentary angular articular serves to preserve their fitting together. To this examined morphologies at parr (juvenile) stage, three levels biological organization—between salmon trout, between sister species...
Introduction When considering treatment options for geriatric patients with lower extremity fractures, little is known about which outcomes are prioritized by patients. This study aimed to determine the patient preferences after a fracture. Materials and Methods We administered discrete choice experiment survey 150 who were at least 60 years of age treated fracture Level I trauma center. The presented participants 8 sets hypothetical outcome comparisons, including joint preservation (yes or...

METHODS: Design : Multicenter retrospective cohort study. Setting: Ten Level I Trauma Centers. Patient Selection Criteria: The inclusion criteria were patients (OTA/AO 33A 33C) nails, a minimum follow-up one year or until reoperation. exclusion...
OBJECTIVES: This study aimed to assess the relationship between postoperative alignment and nonunion in patients with tibial shaft fractures treated intramedullary nailing. METHODS: Design : Retrospective case-control study. Setting: Single academic trauma center. Patients Selection Criteria: Adult closed or open (42A-C) nailing from 2007 2018.
