A 45 year old, right handed bank clerk presented with pain and intermittent locking of the left elbow of 12 months' duration. Pain was intermittent and was activity related. The left elbow locked intermittently on movement, with self manoeuvres of the patient unlocking it. There was no history of trauma or history suggestive of inflammatory arthropathy.

The left elbow had a fixed flexion deformity of 30 degrees with range of motion from 30 to 120 degrees with firm block to further flexion. Rotations of the left forearm were full and pain-free. There was no joint line tenderness. The radiographs of the left elbow are shown below in figs 1 and 2.
