Instability is a common disorder affecting the shoulder in active young individuals. Between April 1993 and March 1996, 10 patients (10 shoulders) underwent a modified Bankart procedure for recurrent anterior shoulder dislocation, at National Taiwan University Hospital. The causes of initial dislocation were sports-related injuries in eight patients and motorcycle accidents in two patients. All patients had at least five recurrences (more than 20 times in five patients) of shoulder dislocation before operation. The operative findings showed positive Bankart lesion and redundant joint capsule in all subjects. A modified Bankart reconstruction with tissue suture anchor (TAG) and T-plasty capsulorrhaphy were performed in each case, followed by a rehabilitation program at outpatient clinics. Patients were followed up for a period of 12 to 30 months, with an average follow-up period of 16.7 months. All patients returned to preoperative activities smoothly. No complications related to the surgery occurred. Only one patient still suffers from occasional shoulder pain while lifting objects. Another patient had one episode of threatened shoulder dislocation at 5 months after surgery, during vigorous exercise. No instability could be detected by manual test at the latest follow up. We used the rating score devised by Rowe et al to determine the preoperative and postoperative score. The average scores were 28.5 preoperatively and 95 postoperatively. The technique is a simple and effective procedure for the surgical treatment of recurrent shoulder dislocation in young and athletic patients.
