Article Abstract
Objective: The objective of this study was to assess outcomes of ballistic distal humeral fracture in comparison with open and closed distal humeral fractures sustained via blunt mechanisms.
Design: Retrospective cohort study.
Setting: Academic Level I trauma center.
Participants: Skeletally mature patients presenting with ballistic (17), blunt open (36), or blunt closed (94) distal humeral shaft fractures (AO/OTA 13A-C).
Main Outcomes: Number of unplanned reoperations, intensive care unit admission, persistent ulnar nerve neuropathy, nonunion, superficial infection, deep infection, heterotopic ossification formation, hardware removal, and length of stay.
Results: A total of 147 distal humeral fractures that underwent operative fixation were included in the study. A group of 17 ballistic fractures and comparison groups of 36 open and 94 closed distal humeral fractures sustained via blunt mechanisms was identified. Compared with the blunt closed group, the ballistic group had a higher proportion vascular injury (p = 0.001), preoperative ulnar nerve injury (p < 0.001), and longer operative times (p = 0.007). Compared with the blunt open group, the ballistic group sustained a higher proportion of preoperative ulnar nerve injuries (p = 0.012), required less olecranon osteotomies (p = 0.045), and had fewer unplanned reoperations (p = 0.043).
Conclusion: Ballistic distal humerus fractures sustain high rates of neurologic and vascular injury but have similar short term outcomes to blunt closed fractures.
Level Of Evidence: Prognostic Level III.

Background: This study evaluates the accuracy of an Artificial Intelligence (AI) system, specifically a convolutional neural network (CNN), in classifying elbow fractures using the detailed 2018 AO/OTA fracture classification system.
Methods: A retrospective analysis of 5,367 radiograph exams visualizing the elbow from adult patients (2002-2016) was conducted using a deep neural network. Radiographs were manually categorized according to the 2018 AO/OTA system by orthopedic surgeons.

Purpose: Recent advancements in medical technologies have made trans-arterial treatment of breast cancer feasible. Consequently, understanding the vascular anatomies of breast cancers and axillary lymph node metastases has become indispensable for sophisticated treatments. The aim of this study was to determine the vascular anatomy of the breast, which is crucial for trans-arterial chemoembolization in patients with breast cancer.

Introduction/background: Complex articular fractures around the knee in the elderly patient present an ongoing challenge regarding optimal treatment. While extensive research has evaluated immediate arthroplasty following fracture of the proximal femur, distal femur, proximal humerus, and elbow, relatively little focus has been given to immediate arthroplasty following complex tibia plateau fractures.
Methods: As seen with many other fractures, arthroplasty can shorten recovery and hospital stay and allow early weight-bearing with improved mobility while minimizing complications and possible future conversion arthroplasty cost.

Recurrent anterior instability with glenoid bone loss is a difficult problem with several surgical options. The Latarjet technique remains the gold standard for glenoid bone reconstruction in the setting of critical glenoid bone loss with excellent long-term outcomes. However, this technique has well known downsides including high rates of complications.

Introduction: The purpose of this study was to determine the rate of conversion to total elbow arthroplasty (TEA) following open reduction and internal fixation (ORIF) with olecranon osteotomy for intraarticular distal humerus fractures.
Methods: This retrospective case series included adult patients who underwent ORIF with olecranon osteotomy for AO/OTA 13C distal humerus fractures between January 2010 and April 2024 at two academic level 1 trauma centers. The primary outcome was the rate of conversion to TEA.
