Question

Identify ONE injury/condition that affects the glenohumeral joint or the related structures of the joint (capsule, ligaments, cartilage etc.). Briefly describe in your own words what the problem is and ensure you identify which anatomical structures are affected.

Important: A reminder this question is asking about conditions affecting the joint not the muscular tissues

Answer 1

Glenohumeral joint is the joint formed by articulation of head of humerus with the glenoid cavity of the scapula. Glenohumeral joint forms the shoulder and is ball and socket type of synovial joint.
ADHESIVE CAPISILITIS : adhesive capsulitis is a common pathological condition that affects the glenohumeral joint. The condition is characterised by adhesion of the joint capsule. The joint capsule is attacked by inflammatory cells and fibroblasts which results in scarring and stiffness of the joint capsule along with reduced synovial fluid. This results in marked stiffness of the shoulder. The condition is characterised by pain, stiffness and loss of shoulder movements. The shoulder muscles may become weak over the time.
Diabetic patients and elderly patients are at high risk of developing adhesive capsulitis.
