Many tears of the anterior supraspinatus tendon and superior subscapularis tendon (anterosuperior rotator cuff) have been found to dissect into the CHL, which may also involve the medial sheath, otherwise known as the SGHL-MGHL complex as …

Oct 18, 2016 · Of the three main ligaments, the SGHL was identified most frequently (94–98 %), the MGHL least frequently (68–84 %) and the IGHL 75–93 % of the time. The SGHL usually originates from the supraglenoid tubercle just anterior to the long head of biceps attachment.

While the shape of the groove contributes to stability of the LHBT, the most important stabilizers are the superior glenohumeral ligament (SGHL), the coracohumeral ligament (CHL), and the interwoven fibres of the subscapularis and supraspinatus [16, 30].

The CHL and SGHL join with fibers from the subscapularis tendon (SScT) and supraspinatus tendon (SST) to form the biceps pulley, stabilizing the LHBT as it enters the bicipital groove where it continues deep to the transverse humeral ligament (THL).

Nov 23, 2012 · Rotator interval capsule (RIC) is anterosuperior aspect of glenohumeral joint capsule, which merges with CHL and SGHL insertions medial and lateral to bicipital groove. CHL arises from base of coracoid process, traverses through subcoracoid fat, and inserts on anterior humerus. IST = infraspinatus tendon. Fig. 1B — Rotator interval.

includes the capsule, long head of the biceps tendon, SGHL, and the coracohumeral ligament that bridge the gap between the supraspinatus and the subscapularis. thin, crescent-shaped sheet of rotator cuff comprising the distal portions of the supraspinatus and infraspinatus insertions.

Rotator interval structures also contribute to the stability of the long head of the biceps tendon. The CHL, SGHL, and subscapularis form a reflection pulley, supporting the bicipital tendon as it exits the glenohumeral joint.

Aug 21, 2020 · The comma sign is a well-known arthroscopic landmark in the identification and repair of the torn subscapularis (SSC) tendon stump. 3, 6-9, 19-21 Lo and Burkhart 14 first described this sign in 2003, defining the comma structure as tissue composed of the superior glenohumeral ligament (SGHL) and coracohumeral ligament (CHL), both detached from ...

Sep 9, 2022 · includes the capsule, SGHL, coracohumeral ligament and long head biceps tendon that bridge the gap between the supraspinatus and the subscapularis.

of the glenohumeral joint capsule . Four structures have been identifi ed as the main components of the glenohumeral ligament complex: the superior glenohumeral ligament (SGHL ), the middle gle-nohumeral ligament (MGHL ), the anterior and posterior inferior glenohumeral ligament (AIGHL, PIGHL), and the la.
