Volar dislocation of the capitate.

In this report we describe a case of volar dislocation of the capitate associated with dislocation of the ulnar side of the carpometacarpal joint. Forced dorsiflexion of the wrist caused the rotation and volar displacement of the proximal portion of the capitate. Dislocation of the capitate is rare and may be seen in more complex injuries. An awareness of this type of injury may contribute to prompt diagnosis and treatment.
