What condition is characterized by inflammation of the glenohumeral joint capsule?

The condition characterized by inflammation of the glenohumeral joint capsule is frozen shoulder, also known as adhesive capsulitis. This condition involves the thickening and tightening of the capsule surrounding the shoulder joint, leading to pain and restricted movement. The glenohumeral joint capsule is essential for providing stability and allowing a full range of motion in the shoulder.

In frozen shoulder, the inflammation induced in the joint capsule results in a significant decrease in mobility, often developing gradually over time. Individuals with this condition commonly experience stiffness and discomfort, particularly during movement. The combination of these symptoms makes it distinct from other shoulder issues.

Other conditions listed, such as shoulder arthritis or bursitis, do affect the shoulder but do not specifically target the glenohumeral joint capsule in the same manner as frozen shoulder. Shoulder arthritis involves inflammation of the joint surface itself, while shoulder bursitis pertains to inflammation of the bursa, which is a fluid-filled sac that reduces friction between tissues. A rotator cuff tear primarily affects the tendons of the rotator cuff muscles and does not involve the capsule's inflammatory response characteristic of frozen shoulder.
