The Anatomy and Function of the Shoulder Joint

The shoulder joint is a delicate balance of mobility and stability. The joint consists of the humeral head and the glenoid fossa, which are covered in cartilage. The stability of the joint is provided by the labrum, ligaments, and dynamic stabilizers like the rotator cuff muscles. The labrum is a rubbery structure that helps deepen the socket and provides suction-like stability. The rotator cuff muscles are responsible for the dynamic stabilization and movement of the shoulder. The shape of the acromion, the bony roof of the shoulder, can influence the risk of injuries like bursitis or rotator cuff tears. A thorough physical examination is crucial in assessing the condition of the shoulder and determining appropriate treatment.
