Simultaneous double dislocation of the interphalangeal joint in a finger.

Isolated traumatic dislocation of the distal and proximal interphalangeal joints of the fingers is a common occurrence. However, simultaneous dislocation of both interphalangeal joints in a single finger appears to be a rare event. We report five cases of simultaneous dislocation of both interphalangeal joints in a single finger with a review of the literature.
