Two-level dorsal dislocation of the little finger.

The case of an elderly man who suffered simultaneous interphalangeal joint dislocation in one finger as a result of a hyperextension force on both the distal and proximal interphalangeal joints is presented. This case differs from the few reports of this type of injury in the literature both in its mechanism of injury and time to reduction. Most reports have been in athletes who are actively involved in a sport, whereas the present case was the result of a fall. Also, successful reduction was achieved almost 2 weeks postinjury, indicating that, even with this amount of delay, these injuries can be effectively treated with closed reduction.
