Since 1967, we have carried out the modified Bristow procedure for treating 110 patients with anterior shoulder dislocation. We focused on patients older than 40 years and investigated the pathology and clinical results in these patients. Clinical records and examination results were available in 10 patients, aged from 40 to 66 years. We found Bankart lesion in 7 patients, Hill-Sachs lesion in 9 and rotator cuff tear in 4.
7 patients were interviewed and examined by the authors. The follow-up period ranged from 5 months to 17 years and one month, with a mean of five years and ten months. The average JOA score was 90.1 points. Rowe's criteria was excellent in 5 patients, good in one and poor in one.
From the above mentioned results it can be suggested that, recurrent anterior shoulder dislocation after age forty may be associated with Bankart lesion and Hill-Sachs lesion at the same rate as for younger patients. In addition there is a moderate incidence of this lesion being complicated with a rotator cuff tear.
