title: Osteochondroma of the distal clavicle: an unusual cause of rotator cuff impingement.
abstract: Rotator cuff impingement symptoms may arise from intrinsic pathologic shoulder lesions related to instability or from extrinsic factors, primarily involving the coracoacromial arch. This report describes 2 unusual cases in which extrinsic impingement resulted from a distal clavicular osteochondroma. In both cases symptoms resolved after resection of the osteochondroma.
