Final answer:
The capsular pattern of the glenohumeral or shoulder joint indicates a predictable sequence of motion loss when the joint capsule is affected—most prominently a decrease in passive external rotation, followed by limits in abduction, internal rotation, and flexion.
Step-by-step explanation:
The capsular pattern of the glenohumeral joint refers to the typical pattern of restriction that occurs when the joint capsule is involved in a pathological condition. While the detailed information does not provide the capsular pattern directly, it is characterized by a greater loss of passive external rotation than abduction, followed by restricted internal rotation and flexion. The glenohumeral joint, often referred to as the shoulder joint, is a multiaxial ball-and-socket joint that permits flexion/extension, abduction/adduction, circumduction, and medial/lateral rotation of the humerus. The joint has a loose articular capsule supported by ligaments such as the glenohumeral ligaments and muscles including the rotator cuff, which provide stability.
