Disorders of the distal radioulnar joint can be classified into functional abnormalities based on instability, incongruity of the joint surface, impaction, and isolated triangular fibrocartilage complex tears. Knowledge of the type of lesion aids in selecting the treatment option best suited to correcting each problem. This review begins by summarizing the anatomy of the distal radioulnar joint. It then examines the various clinical problems that may arise in this complicated anatomic area and outlines the different surgical and nonsurgical options available to treat these disorders. The most important aspect in treatment of disorders of the distal radioulnar joint is early recognition, followed by prompt appropriate surgical or nonsurgical management.

Objective: To report clinical outcomes of skeletally immature dogs with antebrachial deformities secondary to premature closure of the distal radial physis (PCDRP) treated with angular corrections and distraction osteogenesis using circular external skeletal fixation (CESF).
Study Design: Retrospective multi-institutional case series.
Animals: A total of 12 client-owned dogs with premature distal radial physeal closure.
Comparative study regarding the stability of a proximal ulnar stump with or without distal oblique bundle reconstruction during the Sauvé‒Kapandji procedure: a finite-element analysis.

Background: The most common postoperative complication of the Sauvé‒Kapandji (S-K) procedure is proximal ulnar stump instability. The distal oblique bundle (DOB) is a stable tissue used to stabilize the distal radioulnar joint. This study created finite-element models of the distal oblique bundle (DOB) to determine its effect on the proximal ulnar stump instability encountered during the Sauvé‒Kapandji procedure.

Introduction: A form of tenosynovial giant cell tumors (GCTs) that diffusely affects the soft tissue lining of joints and tendons is called pigmented villonodular synovitis or PVNS. About equal percentages of men and women are often affected, and it typically affects young individuals. The most typical sites of PVNS are the knee and ankle, making PVNS of the wrist a rare presentation.

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.
