What is AC Joint Dislocation?

Acromioclavicular (AC) Joint Dislocation is usually caused by a direct fall onto the point of the shoulder. The shoulder blade (scapula) is forced downwards, and the collarbone (clavicle) pops up. It is a particularly common injury in contact sports and cycling.

The three grades for AC injuries

A three-point grading system is used to classify AC Joint Dislocation.

Grade I

  • This is a mild sprain of the AC joint. There is no significant displacement to the collarbone (clavicle). The main ligaments holding the clavicle down, are intact.

Grade II

  • A moderately severe injury to the AC joint. There is some upward displacement of the clavicle which may or may not be visible on examination. The coracoclavicular ligaments are sprained but not completely torn.

Grade III

  • A severe dislocation with complete separation of the joint. There is a very obvious deformity with the end of the clavicle clearly popping upwards. The coracoclavicular ligaments are completely torn.

AC Joint Dislocation with Dr Colvin

The grade of an AC injury will determine its treatment. Grade I and Grade II injuries are usually treated nonoperatively by your orthopaedic surgeon.

Many patients with Grade III AC Joint Dislocations opt for early surgical reconstruction. If not treated surgically the bump is permanent and it may also be cosmetically unacceptable. The majority of Grade III AC joint dislocations typically remain painful without surgical treatment.

Dr Colvin will discuss the pros and cons of AC joint reconstruction with you thoroughly. If you need an experienced orthopaedic surgeon to assist with your AC Joint Dislocation in Perth, call 08 9489 8788
