The shoulder is a complex arrangement of 3 bones held together by muscles, tendons, and ligaments. The clavicle attaches the shoulder to the sternum and holds the shoulder out from the trunk forming the sternoclavicular joint. From behind the shoulder joint the scapula forms two projections, the acromion and the coracoid which together with the clavicle form the glenoid fossa, a socket into which the ball like head of the humerus is cradled. This combination forms the shoulder or glenohumeral joint. The biceps tendon is held in a groove in the humerus and attaches under the rotator cuff.
Bicep tendinitis with pain to the area of the biceptal groove is a common problem.
Injuries may include a roptator cuff tendinitis or tear, A-C joint separation from a fall on the shoulder, and dislocation or glenohumeral instability.
