AC Joint Dislocation
An AC Joint Dislocation is an injury to your acromioclavicular joint.
Your acromioclavicular joint is located at the top of your shoulder and is where your shoulder blade (scapula) meets the end of your collarbone (clavicle).
An AC Joint Dislocation is a stretch or tear of one or more of the ligaments that hold the joint in place. When the ligament tears, your collarbone may move out of its normal place and stick up under the skin just below your shoulder.
Surgery is usually not required. Instead, conservative treatment — such as rest, ice and pain relievers — is often enough to relieve pain. Most people regain full shoulder function within a few weeks after experiencing an AC Joint Dislocation.
