We wished to clarify the clinical efficacy of a modified Bankart and Bristow procedure for a recurrent anterior dislocation of the shoulder. 43 shoulders with recurrent anterior dislocation of the shoulder who had received a modified Bankart and Bristow procedure at our universities or related hospital and were able to be observed for more than five years postoperatively were investigated. There were 35 men and 8 women, and the mean age at operation was 22.1 years old (17-46). The mean follow-up period was 71.3 months (60-88). The operation was done according to Bankart procedure augmented by a coracoid transfer (modified Bristow technique). According to the Rowe scoring system, the clinical results were graded as excellent for 91%, good for 2%, fair for 7%, poor for 0%, with an average score of 94.3 points. There were no redislocations or subluxations post-operatively. The average loss of range of motion compared with the opposite side was 12° for external rotation. 57% of the athletes could return to their preinjury levels. With our method, repairing of the main lesion of the IGHL complex and a buttress effect by the conjoined tendon in abduction seemed to result in a strong stability. This procedure can achieve a good clinical outcome for contact athletes and cases with bony defects of the glenoid or damage to the glenohumeral ligament-labrum complex.
