Posterior superior impingement of the rotator cuff on the glenoid rim as a cause of shoulder pain in the overhead athlete.
A case of impingement of the deep surface of the supraspinatus tendon on the posterior superior rim of the glenoid and mild anterior laxity has been presented. The partial-thickness tear of the undersurface rotator cuff tendon, degenerative tear of the posterior superior labrum, and osteochondral impression fracture of the humeral head have been documented. The purpose of this case report is to present the pathological findings associated with posterior superior glenoid rim impingement and emphasize its role as a cause of shoulder pain in the overhead athlete. In addition it is important to stress the fact that shoulder pain in the overhead athlete may be multifactorial.
