What is sternoclavicular joint?

The sternoclavicular (SC) joint is one of the four joints that complete the shoulder. The joint is located in the spot where the clavicle (collarbone) meets the sternum (breastbone) at the base of the neck. Although not common, problems with the SC joint can arise from injury and other disorders.

What muscles are involved in the shoulder joint?

The primary muscle group that supports the shoulder joint is the rotator cuff muscles. The four rotator cuff muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis. Together the rotator cuff muscles form a musculotendinous cuff as they insert on the proximal humerus.
