In the last 10 years we have found impingement of the coracoid process on the rotator interval in 12 patients (14 shoulders). Seven of these patients were women and 5 were men; the average patient age was 48.5 years. One patient had a calcified coracohumeral ligament, another patient had an anterior tear of a repaired deltoid flap, and a third had an aberrant pectoralis minor tendon inserted into the rotator interval. Eleven patients had a weak rotator interval, and in 4 cases the rotator interval had a small tear. We closed the rotator interval in all 12 patients. We also performed a coracoidoplasty in 5 of the patients. The condition of all shoulders improved clinically after operation; the average follow-up was 4.2 years. Three patients (4 shoulders) still had moderate pain, and 7 patients (9 shoulders) lacked strength. Internal rotation was the only shoulder movement that remained limited. Although impingement seemed obvious during surgery, experimental studies have reported contradictory findings.
