The pitcher's mound: a late sequela of posterior type II SLAP lesions.

Three patients with long-standing disabling shoulder pain underwent arthroscopic examination. Two of the 3 had preoperative magnetic resonance imaging scans showing complete rotator cuff tears confirmed at surgery. The third patient was found to have a partial-thickness bursal surface cuff tear. In addition, each patient was found to have a quite prominent posterior superior glenoid osteophyte located beneath an unstable type II SLAP lesion.
