Virginia residents who have been in car accidents may have suffered shoulder injuries as a result. A fracture or dislocation of the shoulder is a relatively frequent result of a high-speed car accident or collision. To understand what is involved with common shoulder injuries, it helps to understand the joints and bones that make up the shoulder.
The shoulder is made up of three joints and three bones. The bones that make up the shoulder are the arm bone, or the humerus, the collarbone, or clavicle, and the shoulder blade, or scapula. The joints that make up the shoulder are the sternoclavicular joint, acromioclavicular joint and the glenohumeral joint.
