Review Question - QID 7810

A 47-year-old man who works as a carpenter reports a 12-month history of painful mechanical locking of his dominant elbow in the mid range of movement. He also has progressive pain at terminal extension that has not responded to medication, rest, and intra-articular cortisone injection. Active range of movement is from 35 degrees to 130 degrees, and he has full pronation and supination. The ulnar nerve is stable, and he has no subjective or objective neurologic dysfunction in the hand. Radiographs are shown in Figures 22a and 22b. What is the most appropriate treatment?
