Abstract
We evaluated the outcome of open antero-inferior capsular shift in 17 patients with multidirectional instability of the shoulder who failed to respond to conservative treatment. Six shoulders presented with secondary impingement syndrome and 11 with involuntary instability. The mean duration of follow-up was 39 months (range 7-89 months). Based on the Rowe and Constant scores and the 12-item questionnaire of Dawson, the results were rated excellent in 14 patients, fair in 2 and poor in 1. All but 2 patients were satisfied with the results, although 6 patients experienced some residual pain, and 4 suffered minor instability. There were no neurovascular complications, infections or symptomatic posterior instability. Open antero-inferior capsular shift yields promising short-term to medium-term results in multidirectional, involuntary instability of the shoulder.
