- Glenohumeral Joint Anatomy, Stabilizer, and Biomechanics
includes the capsule, SGHL, coracohumeral ligament and long head biceps tendon that bridge the gap between the supraspinatus and the subscapularis long head of biceps acts as humeral head depressor AHI may be normal on Xray but decreased on MRI when pt is supine and weight of arm is removed This usually signifies multiple tendon tear
- Anatomy, Variants, and Pathologies of the Superior . . .
Three ligaments have been described: the superior glenohumeral ligament (SGHL), the middle glenohumeral ligament (MGHL), and the inferior glenohumeral ligament (IGHL) complex, which are composed of an anterior band, a posterior band, and an axillary recess
- Shoulder Ligaments: Anatomy, Function Injuries
Any movement of the arm, particularly above head height involves movement at each of these joints and the shoulder ligaments play an important role in controlling the movement So let’s look at the nine main shoulder ligaments, where they are and what they do 1 Glenohumeral Ligaments
- Relevant Anatomy of Glenohumeral Instability | UW Orthopaedic . . .
While the SGHL and CHL come under tension with external rotation in adduction the middle glenohumeral ligament (MGHL) is tensioned by external rotation when the humerus is abducted to 45 degrees
- Role of middle glenohumeral ligament in external shoulder . . .
The MGHL limits external shoulder rotation with the arm at the side In these 20 cadaveric shoulders, sectioning the MGHL led to a significant mean increase of 15° in external rotation range with the arm at the side but had no clinically significant effect on external rotation with the arm in 90° abduction
- Glenohumeral Ligaments and Unstable Shoulder: CT and MR . . .
The superior (SGHL), middle (MGHL) and inferior (IGHL) glenohumeral ligaments are currently evaluated by shoulder arthroscopy To avoid surgery as a diagnostic procedure, optimization of MR imaging parameters could help to detect lesions of the glenohumeral ligament complexes
