(OBQ13.143) A 17-year-old boy presents with pain in his right elbow for 2 years and limitation in elbow motion bilaterally. He denies any pain or discomfort in his left elbow. He reports no history of trauma to either elbow. He has had two courses of physical therapy, but has noted no noticeable improvement in pain or motion. Examination demonstrates no elbow tenderness on palpation, and there are no neurological deficits. Manual reduction is unsuccessful. The range of motion of both elbows is shown in Figure A. Radiographs of left and right elbow are shown in Figure B and C respectively. What is the most appropriate treatment plan for the right and left elbow? Review Topic
