Comparison of the results of the surgical repair of full-thickness tears of the rotator cuff with and without resection of the lateral clavicle

Abstract

Aim of this study was to compare the results of the surgical repair of full-thickness rotator cuff tears with and without resection of the lateral clavicle. 102 patients were retrospectively observed by an independent observer for a mean follow-up of 21 months (12 - 42). 93 patients had medium to large sized tears (1 - 5 cm) and 9 had massive tears (> 5 cm). Additional resection of the lateral end of the clavicle was performed in 20 patients. The mean age of the 68 men and 34 woman was 57.3 years (28 - 80). For the evaluation the Constant score, the ASES score and the visual analogue scales for postoperative satisfaction, function, strength, pain and ADL were used. The subjective results were good to excellent in 79 patients (76 %), fair in 14 patients (13.7 %) and poor in 9 patients (8.9 %), too. After surgery the Constant score was 87 % of the contralateral side for all patients, 89 % for group I and 84 % for group II and the mean ASES score was 86 %, 87 % and 82 % of the contralateral side. Comparing the pre- and post-operative values on the visual analogue scale pain and disability in ADL were decreased highly significantly in all patients (p < 0.001). We conclude that in patients with a full-thickness rotator cuff tear the patient's satisfaction and function will improve after acromioplasty and rotator cuff repair. The results are not significantly influenced by an additional resection of the lateral clavicle.
