Possible pathomechanism of the capitellar osteochondritis dissecans (OCD) in gymnasts. (A) Weightbearing position with the humerus in external rotation due to scapular dyskinesis. The forearm needs to be in a pronated position during weightbearing (the cubital fossa needs to face front). (B) Weightbearing position with the elbow in hyperextension due to weakness of the triceps muscle.
