Ulnar nerve palsy as a complication of synovial osteochondromatosis of the elbow.

Synovial osteochondromatosis is a rare disease which usually runs a benign course. The knee, hip, elbow and the small joints of the hands and the wrists are the joints most affected, (Chadwick, 1977; Milgram, 1977; Murphy, 1962) and the common complaints are of swelling and stiffness, sometimes associated with locking and pain. We present a case with symptoms and signs of ulnar nerve palsy, due to synovial osteochondromatosis of the elbow.
