Distal ulna fractures, especially styloid injuries, classically have not been repaired, and only recently have these injuries been considered important. Certain fracture patterns of the distal ulna contribute to distal radioulnar joint (DRUJ) incongruity and potential instability. Appropriate fixation of the distal ulna is frequently difficult for several reasons: (1) high incidence of osteoporois in the affected patient population, (2) proximity of the injury to articular surfaces, and (3) lack of a proper implant to treat these injuries. The 2.0-mm locking compression distal ulna plate (LC-DUP) is an anatomically contoured implant with a low profile and fixed angle that provides proper stability to treat injuries of the distal ulna. The plate was designed for the treatment of distal ulna fractures, but its success has led to an extension of its indications to be used in treating symptomatic basistyloid ulnar nonunions and in ulnar shortening osteotomy for ulnocarpal abutment syndrome. The authors' description of the techniques used for each indication as well as their perspectives in the treatment of distal ulna injuries are described in detail in this report.

Anatomy of the distal tendinous structure of the triceps brachii: implications for the role of the triceps brachii to resist valgus elbow forces during baseball pitching.

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.

Introduction: The peripheral radioulnar articulation and the bony radioulnar articulation make up the distal radioulnar joint (DRUJ), a diarthrodial trochoid synovial joint stabilizers for soft tissues. Of the DRUJ's stability, only around 20% may be attributed to the bony articulation. Treatment for DRUJ injuries resulting from a solely ligamentous rupture varies and is subject to debate.
