Osteochondral metatarsophalangeal autografts for traumatic articular metacarpophalangeal defects: a preliminary report.

Abstract

Five consecutive patients with saw injuries to the dorsal portion of the index metacarpophalangeal joint and resultant partial osteochondral defects underwent articular reconstruction using contoured metatarsophalangeal osteochondral autografts. At an average follow-up period of 33 months, all patients achieved full metacarpophalangeal extension, with 74 degrees of flexion and grip strength equal to 86% of the contralateral hand. Discomfort was minimal, with crepitus present in one patient. X-ray films revealed joint space narrowing or articular step-off of 1 mm or less.
