Current Trends in the Management of Proximal Interphalangeal Joint Injuries of the Hand

Injuries to the proximal interphalangeal joint are commonly encountered by the hand surgeon. Proper diagnosis and treatment are vital for optimal outcomes. Proper treatment of these injuries requires a working knowledge of the anatomy of the joint and an appreciation for principles for reduction, stabilization, and early rehabilitation to provide the best outcomes possible. Injuries can include fractures of the head of the proximal phalanx, dislocations, fracture dislocations, and fractures of the base of the middle phalanx. Similar to other aspects of plastic surgery, there is little high-level evidence guiding treatment and thus most treatment is based on level III or IV evidence. The goal for treatment of any injury around the proximal interphalangeal joint is to establish a congruent joint and allow for early motion. Stiffness and posttraumatic arthritis are common following these injuries. Salvage procedures are limited to arthrodesis and arthroplasty, neither of which can restore the normal function of the hand.
