What an AC Joint

An AC joint, also known as the acromioclavicular joint, is a joint that connects the collarbone (clavicle) to the shoulder blade (acromion). It is located at the top of the shoulder and allows for a wide range of arm movements, including reaching, lifting, and throwing.

The AC joint is made up of two bones, the clavicle and the acromion, and several ligaments that hold the joint together. The ligaments work together to provide stability to the joint and allow for smooth movement.

Common AC joint injuries include sprains and dislocations. Sprains occur when the ligaments around the joint are stretched or torn, while dislocations occur when the bones of the joint are forced out of their normal position.

AC joint injuries can be caused by a variety of activities, including sports, work-related accidents, and car accidents. Symptoms of an AC joint injury can include pain, swelling, bruising, and difficulty moving the arm.

Treatment for an AC joint injury typically involves rest, ice, and compression. In some cases, surgery may be necessary to repair the ligaments or bones of the joint.

Recovery from an AC joint injury can take several weeks to months. With proper treatment, most people are able to fully recover from an AC joint injury and return to their normal activities.
