The radioulnar joints and forearm axis: surgeons' perspective

Forearm injuries are common and can vary in complexity. The fractures are easily diagnosed, but the associated soft tissue injuries may not be as obvious. Treatment results are dependent not only on the fracture healing but on the return of normal relationships about the distal radioulnar joint, the interosseous membrane, and the proximal radioulnar joint. Alteration in any of these elements can result in permanent loss of forearm rotation and stability. Recent anatomic and biomechanical studies have increased our knowledge of these structures and their role in forearm function. The findings from these studies may lead to earlier repair of soft tissue injuries about the radioulnar joints and the interosseous membrane. Further follow-up of these procedures will be needed to validate their indications.
