The shoulder complex actually involves several joints working together, though the glenohumeral joint — where the humeral head meets the shallow glenoid socket of the scapula — is the primary ball-and-socket articulation responsible for most arm motion.

Shoulder · How common is shoulder pain?
Shoulder pain is one of the most frequently reported musculoskeletal complaints, with population studies suggesting a substantial share of adults experience an episode at some point, particularly with advancing age. Occasional painless clicking is common and often not concerning, but clicking accompanied by pain, catching, or a sense of the joint giving way warrants further evaluation.

This trade-off between mobility and stability explains why shoulder rehabilitation places heavy emphasis on rotator cuff and scapular muscle control rather than joint mobility alone. Shoulder abduction, lifting the arm out to the side and overhead, represents the joint's largest range of motion and requires coordinated movement between the humerus and scapula to achieve its full arc.
Shoulder · Deltoid
This large, superficial muscle covering the shoulder provides the bulk of the force for lifting the arm, working together with the smaller rotator cuff muscles that fine-tune joint positioning. Shoulder conditions span a spectrum from tendon overuse and irritation to structural tears, joint stiffness, and instability, with several conditions often overlapping in presentation.
