The clinical results of rotator cuff surgery were usually satisfactory. However, in some cases, the clinical symptoms recurred after rotator cuff surgery.
We wish to present five cases of subcoracoid impingement syndrome after surgery of the rotator cuff tear. Five patients were diagnosed as having subcoracoid impingement syndrome after the surgery for a rotator cuff tear. The average age of the five patients was 66 years (60 to 78 years), All the patients had had Neer's anterior acromioplasty and surgery for a rotator cuff tear (repairs-2, latissimus dorsi transfer-1 and partial resections-2). The tear size of the rotator cuff at the initial surgery was two incomplete and three massive. Subcoracoid impingement syndrome was diagnosed by effective subcoracoid block with 1.5cc of 1% Lidocaine. All the patients had anterior shoulder pain at horizontal flexion, the x-rays revealed a superior migration of the humeral head. CT findings represented a narrowing of the coraco-humeral space. Coracoplasty was performed on three patients, after which, their symptoms disappeared. Intraoperative findings revealed degenerative changes of the subscapularis tendon and anterior of the humeral head in all cases. The coracoacromial ligament was adherent to the deltoid in two cases.
Subcoracoid impingement syndrome is one of the important causes of anterior shoulder pain after surgery for a rotator cuff tear.
