To determine the outcome of the Bankart procedure through lateral capsulotomy approach by objective and subjective evalua-tion in traumatic anterior instability of the shoulder.

Thirty-seven patients with traumatic anterior instability, who underwent the Bankart procedure through lateral capsulotomy, were investigated with an average follow-up of 23 months. Every effort was made to maximize the range of motion by repairing the Bankart lesion and closing the capsulotomy to allow as much external rotation as feasible. In 18 cases, superior capsular shift (13) or Neer 's capsular shift (5) were combined to deal with capsular redundancy. Outcome was assessed using range of motion, Pennsylvania Shoulder Function Score, pain, residual symptom and satisfaction.

Recurrence of instability was not encountered. Function score increased significantly and all patients were satisfied with the results. However, 8 patients (22%) complained of feeling apprehensive about sports activities.

The Bankart procedure through lateral capsulotomy appears to minimize unwanted external rotation limitations and enable capsular redundancy to be dealt with adequately.
