Brachymesophalangy and loose bodies in the metacarpophalangeal joints.

A family with autosomal inherited brachymesophalangy is presented. Some of the family members also had loose bodies in the metacarpophalangeal joints. This condition is similar to osteochondritis in other joints. New loose bodies may be formed after operative removal and arthrotic changes may occur. The patients were not able to perform hard physical work with their hands.
