Understanding the structure of the shoulder and how it works will help you better understand how impact occurs. Muscles, tendons, ligaments and bursae also make up the shoulder joint. Impingement can also be caused by a shoulder injury. An acromion is a prominent bony protrusion at the top of the shoulder joint.
