Arthrography of shoulder joint (with or without computed tomography) is performed by injecting contrast below and lateral to the coracoid process to outline the shoulder joint. Axillary pouch of the shoulder can be seen on external rotation, while subscapular (subcoracoid) bursa can be seen on internal rotation of arm. The contrast should not ...
In human anatomy, the glenohumeral ligaments (GHL) are three ligaments on the anterior side of the glenohumeral joint (i.e. between the glenoid cavity of the scapula and the head of the humerus; colloquially called the shoulder joint).
In human anatomy of the arm, the capitulum of the humerus is a smooth, rounded eminence on the lateral portion of the distal articular surface of the humerus. It articulates with the cup-shaped depression on the head of the radius , and is limited to the front and lower part of the bone.
The capsule of the glenohumeral (shoulder) joint is the articular capsule of the shoulder.It completely surrounds the joint. It is attached above to the circumference of the glenoid cavity beyond the glenoidal labrum, and below to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent.
It affords attachment to the articular capsule of the shoulder-joint, and is perforated by numerous vascular foramens. Fracture of the anatomical neck rarely occurs. [2] The anatomical neck of the humerus is an indentation distal to the head of the humerus on which the articular capsule attaches. Anatomical vs surgical neck of humerus
It gives attachment to the capsular ligament of the shoulder joint except at the upper inferior-medial aspects. It is best marked in the lower half of its circumference; in the upper half it is represented by a narrow groove separating the head of the humerus from the two tubercles, the greater tubercle and the lesser tubercle .
The olecranon fossa is located on the posterior side of the distal humerus. [ 1 ] [ 2 ] The joint capsule of the elbow attaches to the humerus just proximal to the olecranon fossa.
The subscapularis stabilises the shoulder joint by contributing to the fixation of the proximal humerus during movements of the elbow, wrist, and hand. [1] It is a powerful defense to the front of the shoulder-joint, preventing displacement of the head of the humerus. [citation needed]
