Glenohumeral Joint





- See: Shoulder Menu:

- Anatomy:
    - GHJ has a greater ROM than any other joint;
    - Bony Anatomy:
         - its shallow, & is more akin to a grapefruit in saucer than ball in socket.
         - lack of bony stability & wide ROM permitted by loose ligamentous & capsular reinforcement account for fact that glenohumeral is most frequently dislocated joint in body.
    - Shoulder Capsule (see anatomy)
    - Muscular Stabilizers
    - Subacromial Bursa
    - Subdeltoid bursa lies on top of Rotator cuff & greatly facilitates movement of the cuff beneath the coracoacromial arch;
    - Coracoid
    - Coraco-acromial ligament:
          - one finger breadth lateral to Coracoid is glenohumeral joint, so coracoid process is important landmark in locating GHJ for aspiration or injection;

- Scapulothoracic Motion:
    - shoulder motion also occurs between Scapula & post thoracic wall;
    - when arm is abducted to 180 deg, there is approx 1 deg of scapulo-thoracic motion for every 2 deg of glenohumeral motion;
    - ratio of glenohumeral to scapulothoracic motion may vary normally depending on arm elevation in the scapular plane.
          - ratio has not been shown to play a role in glenohumeral stability
