The anterosuperior part of the labrum also inserted into the fibres of the middle or inferior glenohumeral ligament
in many specimens (Cooper et al 1992).
Other findings in this case included partial tear of the supraspinatus tendon and superior glenohumeral ligament
The three most common labral variants include a sublabral foramen with a cord-like middle glenohumeral ligament
(MGHL) occurring in 8.
External rotation greater than 90[degrees] at the side is suggestive of anterior ligamentous hyperlaxity; asymmetrical hyperabduction of more than 20[degrees] compared to the contralateral arm is indicative of a stretched inferior glenohumeral ligament
The rivet was designed as a removable metallic device for affixing the torn labrum and the inferior glenohumeral ligament
(IGHL) to the glenoid margin.
The glenohumeral ligaments
are collagenous band-like structures that reinforce the thin capsular tissue.
The anterior glenohumeral ligament
complex consists of the superior glenohumeral ligament
(SGHL), middle glenohumeral ligament
(MGHL), the anterior band of the inferior glenohumeral ligament
(AIGHL), and the anterior labrum.
The anatomic repairs tend to address the detachment of the anterior inferior glenohumeral ligament
from the anterior inferior labrum, the classical Bankart lesion.
7,8) Secondly, the appearance of a cord-like middle glenohumeral ligament
, with an absent anterosuperior labrum, coined the Buford complex, has also been described.
When the humerus is abducted to 90[degrees] and higher--occurring during the early cocking phase and continuing until the follow-through phase--the inferior glenohumeral ligament
limits anterior and posterior translation of the humeral head on the glenoid.
Maffet and coworkers23 added three additional types to Snyder's classification: Type V lesions involve an anteroinferior Bankart lesion extending upward to include separation of the biceps tendon; Type VI lesions consist of an unstable radial or flap tear associated with separation of the biceps anchor; and Type VII lesions involve extension of the SLAP lesion beneath the middle glenohumeral ligament
They reported a high variability in pathologic lesions associated with glenohumeral instability, including anterior glenoid labral tears (87%), anterior capsule deficiency (79%), Hill-Sachs lesions (68%), glenohumeral ligament
disruptions (55%), rotator cuff tears (14%), posterior labral tears (12%), and SLAP (superior labrum, anterior to posterior) lesions (7%).
