Joint separation, also known as acromioclavicular joint separation or AC separation, is a common injury that affects the joint between the collarbone (clavicle) and the acromion (part of the shoulder blade). This type of injury usually occurs as a result of a direct blow or fall onto the shoulder, such as during a sports activity or a motor vehicle accident.
Treatment for AC joint separation depends on the severity of the injury, and may include rest, ice, pain management, physical therapy, and surgery in more severe cases. Recovery time varies but typically takes several weeks to several months.
