Acromioclavicular Joint and Coracoclavicular Ligament Reconstruction
The acromioclavicular joint (AC joint) is a joint that connects the collarbone (clavicle) to the shoulder blade (scapula). It is a small joint that helps to stabilize the shoulder and allow for movement of the arm. An acromioclavicular joint separation, also known as an AC joint sprain or AC joint injury, is an injury to the AC joint. It is caused by a fall or a direct blow to the shoulder that forces the clavicle away from the scapula.
AC joint separations are classified into six grades, depending on the severity of the injury. Grade 1 separations are the mildest and involve stretching of the ligaments that hold the AC joint together. Grade 6 separations are the most severe and involve complete rupture of the ligaments. Grades 1-3 AC joint separations can usually be treated with non-surgical treatment, such as rest, ice, compression, and elevation (RICE). Grade 4-6 AC joint separations may require surgery to repair the ligaments and stabilize the joint.
AC joint reconstruction is a surgery to repair the ligaments that hold the AC joint together. The surgery can be performed minimally invasive, which means that it is done through small incisions in the shoulder. During surgery, we use a camera and small instruments to view the inside of the shoulder. We then repair the ligaments by a combination of sutures and graft material to restore biomechanical stability. In certain cases, we may remove the edge of the clavicle to allow normal alignment and prevent future pain.
AC joint reconstruction is a safe and effective procedure that can provide relief from pain and improve function of the shoulder. The procedure usually takes about 1 hour to perform and patients typically go home the same day from surgery.
Risks and Complications
As with any surgery, there are some risks associated with AC joint reconstruction. These risks include:
Infection
Bleeding
Nerve damage
Thrombosis
Reaction to anesthesia
Recovery
Recovery from AC joint reconstruction usually involves wearing a sling for several weeks. Physical therapy will help to improve range of motion and strength in the shoulder.
Most patients are able to return to their normal activities within 6-12 weeks after surgery. However, it is important to listen to your body and not push yourself too hard during recovery.
