Abstract
The modified Magnuson-Stack procedure of lateral and distal transfer of the insertion of the subscapularis muscle was used in 38 consecutive patients with recurrent anterior dislocation of the shoulder, all of whom have been followed-up for a minimum of three years. There was only one failure; the other 37 patients had an excellent or satisfactory result with an adequate range of movement. Bankart and Hill-Sachs lesions were not a constant finding but subscapularis laxity was detected in almost every case, an observation that helps to confirm its central role as a cause of recurrence.
