Normal Left Shoulder Anatomy vs. Adhesive Capsulitis
This exhibit compares the normal anterior shoulder anatomy and adhesive capsulitis. Anatomical structures include: the clavicle, coracoid process, acromion process, supraspinatus, humerus, bursa, glenohumeral joint capsule, biceps brachii, and the scapula. Adhesive capsulitis (also known as frozen shoulder) is a rheumatic condition in which the connective tissues of the glenohumeral joint become inflamed and stiff, restricting shoulder movements. This condition can be induced by trauma, arise progressively as a degenerative condition, or be idiopathic in nature. Patients usually present with a lack of synovial fluid, severe scar tissue adhesions, and thickened capsular tissue.
