Irreducible dorsal dislocation of the distal interphalangeal joint: case report and literature review.

An irreducible dorsal dislocation of the DIP joint is a rare injury. Irreducibility is primarily caused, in closed injuries, by the interposed volar plate, and in open injuries by the dislocated FDP tendon. It is important to recognize the complex nature of this dislocation and to limit attempts at closed reduction. Early surgical exploration, anatomic reduction, and early mobilization are prerequisites to good functional recovery.
