Forearm Instability: Anatomy, Biomechanics, and Treatment Options

J Hand Surg Am. 2017 Jan;42(1):47-52. doi: 10.1016/j.jhsa.2016.10.017.

Abstract

The forearm unit consists of the radius and ulna, a complex and interrelated set of joints (distal radioulnar joint, proximal radioulnar joint) and the soft tissue stabilizers between the 3 bones. Distally, this is represented by the triangular fibrocartilage complex at the wrist, proximally by the annular ligament at the elbow, and in the forearm by the interosseous membrane. Disruptions in any of these structures may lead to forearm instability, with consequences at each of the remaining structures.
