Displaced intra-articular osteochondral fracture--cause for irreducible dislocation of the distal interphalangeal joint.
One cause of irreducible dislocation of the distal interphalangeal joint is the interposition of the palmar plate or the flexor tendon between the joint surfaces. This case report describes another cause for an irreducible dislocation. Radiographic findings on the initial films are discussed to alert the attending physician to the possibility of an osteochondral fracture. Open reduction resulted in an essentially normal joint 17 months later.
