Labral lesions were associated with anteriosuperior labral fraying, an abnormal superior glenohumeral ligament and increased passive internal rotation range of motion.
It also provides an attachment site for the shoulder capsule, glenohumeral ligaments and the tendon of the long head of the biceps muscle.
Humeral avulsion of glenohumeral ligaments
as a cause of anterior shoulder instability.

10) In addition, the glenohumeral ligaments and capsule attach to the fibrocartilaginous zone of the labrum.
Williams MM, Snyder SJ, Buford D Jr: The Buford complex- the "cord-like" middle glenohumeral ligament
and absent anterosuperior labrum complex: a normal anatomic capsulolabral variant.
Normally, external rotation of the humerus creates tension in the glenohumeral ligaments
, especially the inferior glenohumeral ligament
Bencardino and colleagues (24) found that SLAP lesions were associated with partial rotator cuff tears in 42% of patients, frayed or lax inferior glenohumeral ligaments
in 26%, Bankart lesions in 16%, Hill-Sachs lesions in 16%, chondral lesions in 16%, loose bodies in 10%, complete rotator cuff tears in 5%, and posterior labral tears in 5%.
Patients with unidirectional, traumatic anterior instability, with a discrete Bankart lesion and with well developed glenohumeral ligaments
, who do not participate in collision athletics, are ideal for an arthroscopic procedure.
With this technique, the anterior stabilizing function of the subscapularis and glenohumeral ligaments
