AI Article Synopsis
Article Abstract
Introduction: Giant cell tumors (GCT) are a relatively uncommon type of non-cancerous bone growth, representing around 4-10% of all bone tumors. These tumors tend to exhibit local aggressiveness and are typically prevalent in individuals between 20 and 40 years old. Commonly observed locations for GCT include the distal femur, proximal tibia, and the distal end of the radius. However, occurrences at the distal end of the ulna are rare, accounting for only 0.45-3.2% of cases.
Case Report: In this instance, we present the case of a 36-year-old male diagnosed with a GCT specifically located in the left distal ulna. Our approach involved managing the patient through the complete removal (en-bloc resection) of the distal ulna. Following this, we performed an extensor carpi ulnaris (ECU) tenodesis to stabilize the proximal stump. After 2-year follow-up, the patient exhibited positive outcomes, displaying satisfactory wrist joint mobility and functionality without any signs of tumor recurrence.
Conclusion: This case emphasizes the effectiveness of wide resection as a viable treatment for huge GCTs in the distal ulna. Utilizing tenodesis with the tendon of ECU significantly contributes to stabilizing the ulnar stump, leading to improved wrist function.

Purpose: Distal radius fractures (DRFs) are often initially assessed by junior doctors under time constraints, with limited supervision, risking significant consequences if missed. Convolutional Neural Networks (CNNs) can aid in diagnosing fractures. This study aims to internally and externally validate an open source algorithm for the detection and localization of DRFs.

Background: Biomechanical studies suggest that the triceps brachii muscle generates resistive force against valgus stress on the elbow during baseball pitching. However, given the parallel fiber orientation in the distal tendinous structure of the triceps brachii, the mechanism behind this anti-valgus force remains unclear. In the present study, we aimed to examine the anatomy of the distal tendinous structure of the triceps brachii using bony morphological, macroscopic, and histological methods.

Background: Distal radius physeal injuries can result in growth arrest and progressive deformity in children. Ulnar epiphysiodesis may be used to prevent deformity in the skeletally immature child; however, predicting success may be challenging. The purpose of this study was to (1) develop a method to predict successful ulnar epiphysiodesis, and (2) determine the utility of adding a sliding bone autograft as an adjunct to achieving successful epiphysiodesis.

Distal radius fracture nonunion can result in significant deformity, loss of function, and chronic pain. Presented here is a case of distal radius nonunion that was surgically reconstructed with a pedicled distal ulna bone graft based on the periosteal branches of the posterior interosseus artery (PIA). This technique has limited prior utilization for adult distal radius nonunion treatment but offers an effective option for surgical reconstruction of distal radius nonunion with preservation of the radiocarpal joint, utilizing a less invasive surgery that also reduces hospitalization stay.

Introduction: Post-traumatic arthritis of elbow is a crippling condition that frequently develops after a serious joint injury. The condition is characterized by pain, rigidity, and diminished functionality, considerably affecting the quality of life of those impacted. Despite advancements in surgical and conservative management, the optimal treatment strategy remains elusive.
