Abstract

Traumatic injuries of the distal radioulnar joint (DRUJ) is important problem that requires special consideration for treatment to prevent disability arising from failure to the diagnosis, treatment, and rehabilitation. Stability of the DRUJ is provided by a combination of bony and soft tissue architecture. The bony architecture of the DRUJ account for only 20% of the DRUJ stability and soft tissues including triangular fibrocartilage complex (TFCC), pronator quadratus, and interosseous membrane give major role on the stability. TFCC is generally accepted as the most essential soft tissue stabilizer of the DRUJ. Acute dislocation of DRUJ injury is commonly associated with forearm fractures but it occurs as an isolated injury even though it is relatively rare. DRUJ injury is the one of main source of chronic wrist pain, instability and the focus of this article is on acute dislocation injury of DRUJ and their management.
