What is AC joint pain?
The acromioclavicular joint, also called the AC joint is located at the top of the shoulder where the highest part of the scapula, called the acromion, meets the clavicle (collarbone). You can feel your AC joint on the outside and top of the shoulder. There are many conditions that can cause AC joint pain, the most common are fractures, separations and arthritis. Trauma, separations, or the loss of cartilage in the AC joint, can cause pain, swelling and limited range of motion. Dr. Armando Vidal, orthopedic shoulder specialist, treats patients in Vail, Aspen and the surrounding Denver, Colorado communities who are suffering from AC joint pain.
