Shoulder separation
A shoulder separation (acromioclavicular joint injury) occurs when the outer end of the collarbone (clavicle) separates from the end (acromion) of the shoulder blade because of torn ligaments. This injury occurs most often from a blow to a shoulder or a fall on a shoulder or outstretched hand or arm.
Signs and symptoms of a separated shoulder include:
- Severe pain at the moment the injury occurs.
- Limited movement in the shoulder area (because of pain, not weakness).
- Swelling and bruising.
- Possible deformity. The outer end of the collarbone may look out of place, or there may be a bump on top of the shoulder.
Treatment may include applying ice, keeping the shoulder still (immobilized) with a sling or wrap, and taking medication to relieve pain, inflammation, and swelling. After symptoms improve, physical therapy may help strengthen muscles in the shoulder region and prevent frozen shoulder (adhesive capsulitis). Occasionally surgery may be needed to repair torn ligaments.
Healing may take 2 to 10 weeks, depending on the severity of the injury.
