Bilateral Trans-Scaphoid Perilunate Fracture Dislocation

The wrist represents a complex anatomic region in the human extremity and a highly functional and intricate structural joint. Most perilunate injuries result from a staged disruption of the ligamentous structures. Forces may be directed through the carpal bones themselves resulting in a fracture. Early anatomic reduction of any carpal malalignment is of the utmost importance. Unfortunately, even with optimal treatment, outcomes after perilunate injuries are frequently poor. Generalized wrist stiffness, diminished grip strength, and post-traumatic arthritis commonly develop. Scaphoid fractures are frequent in everyday practice. But associated fractures of the scaphoid and capitate with 90�180�rotation of the head of the capitate are rare wrist injuries. This carpal bone injury has been defined by Fenton and Rosen since 1950. The Fenton syndrome should be recognized especially in great external force.
