A separated shoulder (also known as acromioclavicular separation, AC joint separation, AC separation), is a common injury to the acromioclavicular joint. This is not to be confused with shoulder dislocation which occurs when the humerus separates from the scapula at the glenohumeral joint. The trauma to the shoulder affects the ligaments holding the two bones—the scapula and the clavicle—together. This injury does not always involve bone fractures; however if the impact to the shoulder is severe, fractures may occur.
Symptoms of a dislocated shoulder are as intense pain as soon as the injury occurs, tenderness of the shoulder and collarbone, swelling, bruising, deformed shoulder.
Treatment of a separated shoulder depends on the severity of the injury. When beginning treatment some of the things one should do first, is control the inflammation, rest the joint, and ice the joint. Rest the joint which will also help minimize painful symptoms and allow the healing to begin. When icing, it should be done every four hours for 15 minutes at a time. Surgeries like Weaver-Dunn procedure, arthroscopic can be done. Physical therapies such as external shoulder rotation, shoulder extensions can also be performed.
