Simultaneous dorsal dislocation of the proximal and distal interphalangeal joints in one digit.

Dorsal dislocation of a proximal and distal interphalangeal joint is a common clinical problem. However, simultaneous dorsal dislocation of both interphalangeal joints in a single digit is rare. We describe the first case of an open, simultaneous proximal and distal interphalangeal dislocation. Patient outcome following vigorous wound care, closed reduction, and four weeks of immobilization was excellent. Review of reported cases revealed that these injuries occur most commonly in men, on the dominant hand, and in association with sporting injuries or falls, and typically have a good outcome following closed reduction and splinting.
