The acromioclavicular joint, or AC joint, is a small but important joint at the top of the shoulder. It is the junction between the acromion (part of the scapula that forms the highest point or bony roof of the shoulder) and the clavicle. The AC joint connects the clavicle to the acromion of the scapula and presents an important part of the overall shoulder function and biomechanics. The AC joint is stabilized by several separate ligaments including the acromioclavicular (AC) ligaments and coracoclavicular (CC) ligaments. Injuries to the AC joint can result from acute trauma, such as acromioclavicular joint separations, or from chronic overuse (i.e. AC osteoarthritis):
Treatment of these frequent AC joint conditions is best be performed by an experienced shoulder specialist that understands the entire spectrum of non-operative and surgical treatment options. Should surgical treatment be necessary, Dr. Mithoefer can typically performs these procedures minimally invasively with arthroscopic technique to minimize postoperative pain and to facilitate recovery:
