Impingement of the tendinous rotator cuff on the coracoid process (subcoracoid impingement syndrome) has rarely been reported as a cause of pain after surgery for rotator cuff tear. We evaluated clinical features, surgical results, and histopathology Findings of resected coracoid processes in patients with subcoracoid impingement syndrome after anterior acromioplasty and management of rotator cuff tear. Pain at the anterior aspect of the shoulder, localized tenderness of the coracoid process, anterior shoulder pain on horizontal adduction testing, and positive subcoracoid block suggest subcoracoid impingement syndrome. Postoperative subcoracoid impingement syndrome was investigated in 11 of 216 cases with rotator cuff surgery The average patient age at the time of surgery was 61.2 y (range, 28-78 y). Coracoplasty (partial resection of the posterolateral side of the coracoid process) was performed in 9 shoulders that had not responded to a 6-month regimen of conservative treatment. Complete pain relief was achieved in all cases. Histopathologic findings revealed hypertrophic changes of the fibrocartilage layer at the posterior aspect of the resected coracoid process. We concluded that subcoracoid impingement syndrome was an important Factor in unsuccessful rotator cuff surgery and recommend that coracoplasty be performed on patients with symptoms of subcoracoid impingement syndrome after management of the rotator cuff tear.
