Role of contracture of the coracohumeral ligament
and rotator interval in pathogenesis and treatment," The Journal of Bone & Joint Surgery--American Volume, vol.
Sometimes, though not in this series, it is necessary to release the anterior capsule of the glenohumeral joint through an anterior approach or the coracohumeral ligament
Quantitative criteria: (i) a coracohumeral ligament
thickness of 4 mm or more, (ii) thickness of capsule at the rotator cuff interval of 7 mm or more; qualitative criteria: (i) an abnormal coracohumeral ligament
, (ii) obliteration of the subcoracoid fat triangle, and (iii) synovitis-like abnormality at superior border of subscapularis tendon.
The stability of the shoulder is in large part due to the shoulder capsule, which includes the synovial membrane, the fibrous capsule consisting of the coracohumeral ligament
, and the superior, middle, and inferior glenohumeral ligaments.
However, anatomic studies have also demonstrated that the coracohumeral ligament
(CHL) forms an anterior band around the proximal biceps tendon and may be its primary stabilizer.
