The capsulolabral complex is a critical anatomical structure of the shoulder joint that provides stability by integrating the joint capsule and the labrum. It plays a vital role in preventing dislocations and maintaining the functional integrity of the shoulder during movement.

Capsulolabral Complex

Anatomical structure of the shoulder joint

The joint capsule is a fibrous connective tissue structure that surrounds synovial joints, providing stability while allowing for movement. It consists of an outer fibrous layer and an inner synovial membrane, which produces synovial fluid to lubricate the joint.

Joint Capsule

The labrum is a ring of cartilage that surrounds the socket of ball-and-socket joints, such as the shoulder and hip, providing stability and cushioning to the joint. It plays a crucial role in joint function, and injuries to the labrum can lead to pain, instability, and reduced range of motion, often requiring surgical intervention for repair.

Labrum

Shoulder joint stability is crucial for maintaining the functional integrity of the shoulder, preventing dislocations, and ensuring efficient movement. It relies on a complex interplay of static and dynamic stabilizers, including ligaments, the joint capsule, and the rotator cuff muscles.
