Camptodactyly caused by abnormal insertion and origin of lumbrical muscle.
A 12-year-old boy had camptodactyly of the little finger. Operative findings revealed an abnormal origin of the lumbrical muscle from the transverse carpal ligament, and abnormal insertion into the tendon sheath of the flexor digitorum superficialis tendon. No similar case has been reported in the literature.
