Fig. 1A —23-year-old man who had intermittent painful subluxation of
elbow during military training. He had a history of dislocation of his elbow 4
years earlier and had splint immobilization for 3–4 weeks. Radiographs
show nonunited lateral condyle fracture fragment posterolateral to radial
head, which lost its normal contact with capitellum.

Fig. 2 —Proposed pathoanatomy of osteochondral defect we call
"Osborne-Cotterill lesion." Drawings show normal articulation of
radiocapitellar joint (A), hyperextension of elbow joint loading shear
force at posterior capitellum (B), and radial head engaged in bone
defect with injury to lateral ulnar collateral ligament (C).
