Chronic fracture-subluxation of the proximal interphalangeal joint.

Reported methods of treatment of chronic fracture-subluxations of the proximal interphalangeal joint require wide dissection and prolonged immobilization and often result in limited motion. Open reduction with minimal dissection, immobilization for 11 days to allow soft-tissue healing, and the early institution of active flexion exercises protected by an extension block splint was done in four patients. The long-term results demonstrate restoration of a stable joint with satisfactory motion and minimal subjective complaints.
