Distal Clavicle Excision
What is Distal Clavicle Excision?
Distal clavicle excision is a procedure which involves removal of the outer end of the clavicle (collarbone) to treat shoulder pain and disability due to arthritis or impingement.
Anatomy of the Shoulder
The shoulder is formed by three bones, the humerus (upper arm bone), scapula (shoulder blade) and clavicle (collar bone). The head of the humerus fits into a cavity at the side of the scapula called the glenoid to form the glenohumeral joint. A projection of bone from the scapula called the acromion joins the outer end of the clavicle to form the acromioclavicular (AC) joint.
Indications for Distal Clavicle Excision
The AC joint can undergo sudden trauma or degeneration due to osteoarthritis as a result of aging and increased athletic and overhead activities. Impingement of the soft tissues can occur between the humeral head and the acromion. Damage to the rotator cuff can result in abnormal positioning of the head of the humerus creating pressure on the AC joint above, resulting in arthritis.
Your doctor may initially recommend conservative treatments such as rest, ice application, anti-inflammatory medication, and physical therapy. Distal clavicle excision is recommended if these interventions fail to relieve your symptoms. Removing this portion of the bone will decompress the joint and will help ease the pain and loss of motion caused by shoulder impingement or shoulder arthritis.
Procedure for Distal Clavicle Excision
Distal clavicle excision can be performed both arthroscopically as well as through open surgery. Your doctor will decide the appropriate surgical option based on your condition. However, arthroscopic distal clavicle excision is the preferred option due to its advantages of minimal complications, less downtime, negligible blood loss, and small incisions.
The procedure will be performed under anesthesia while you are seated in a beach-chair position. After adequately sterilizing the surgical area, a few keyhole-size incisions are made through which an arthroscope and tiny cutting instruments are inserted. Excision of the end of the clavicle at the acromioclavicular joint in the shoulder is carried out. The incisions are then closed with sutures and dressings are applied.
Recovery following Distal Clavicle Excision
Following distal clavicle excision, you will be taken to the recovery room. Your shoulder will be wrapped with dressings and immobilized in a sling. An ice pack is recommended to control pain and swelling. You will also receive pain medications. You may be allowed to leave the same day. The shoulder sling should be used for about 3 to 6 weeks. Instructions will be given on how to remove the sling and perform a gentle range of motion exercises. Avoid strenuous activities for at least a month.
