DIAGNOSIS AND TREATMENT OF TRAUMATIC ANTERIOR INSTABILITY OF THE SHOULDER

Traumatic anterior glenohumeral joint dislocation is the most common t ype of shoulder instability. Lesions that usually result are avulsion of the anterior capsule and glenoid labrum from the glenoid rim (Banka rt lesion), compression fracture of the posterosuperior humeral head ( Hill-Sachs lesion), and laxity of the joint capsule. Another common le sion is a lengthwise disruption of the rotator cuff at the interval be tween the subscapularis and supraspinatus tendons. The shoulder that d islocates repeatedly after trauma has an excellent success rate when t reated by surgical repair. The aim of the Bankart procedure is to rest ore stability to the shoulder by repairing the traumatic lesion of the anterior glenoid rim without altering normal anatomy.
