Abstract:
PURPOSE: To evaluate the function of the shoulder and the effect of the division of the subscapularis tendon on the strength of the inter-nal rotator after capsular imbrication and Bankart repair. MATERIALS AND METHODS: From January, 1996 to December, 2000, we reviewed thirty cases of traumatic anterior shoulder instability, which underwent capsular imbrication and Bankart repair. The follow up period was minimally one year. The clinical results were evaluated using the ASES (American Shoulder and Elbow Surgeons) score and the muscle power of the internal rotator as measured by a myometer. RESULTS: All cases showed satisfactory results; nineteen cases (63%) were excellent, and eleven cases (37%) were good. Mean value of ASES score increased from 78.6 (60-82) ponts to 94.5 (84-100) points. Mean value of the score increased was 16 (14-38) points. Postoperatively, the muscle power of the internal rotator compared with contralateral was increased in 12 cases (40%), decreased in 17 cases (57%), and was the same in one case (3%). There was no cases of deterioration of function, recurrence or requiring revision surgery. CONCLUSION: In capsular imbrication and Bankart repair, the division of the subscapularis tendon did not produce a significant adverse effect in the strength of the internal rotator. We believe that this is one of the useful treatment methods in traumatic anterior shoulder insta-bility, because it provides stability and a good range of motion.
