The main image on this chart shows the bones, muscles, ligaments, veins, and arteries of the shoulder. The chart illustrates posterior, lateral, anterior, and superior views of the shoulder anatomy, as well as the socket of a normal shoulder joint. Images show impingement syndrome, rotator cuff tear, trauma (such as proximal humeral fracture and acromioclavicular separation), and bicipital tendon problems. The chart also illustrates instability such as anterior dislocation of the humerus, Bankart lesion, and Hill Sachs formation.
