AC JOINT INJURIES (ACROMIOCLAVICULAR)

The AC joint is located at the top of the shoulder joint and is made up by the bony prominence of the the acromion on the scapula (shoulder blade) and the end of the clavicle (collarbone).
 
The joint is supported by 3 ligaments:
1. Acriomio-clavicular ligament
2. Coracoacromial ligament
3. Coroco-clavicular ligament (made up the conoid and trapezoid ligament)
 
The main function of the AC joint is:
- To allow/prevent the scapular within a optimal range of rotation
- Allow for force transmission from the arm to the shoulder

WHAT CAUSES AN AC JOINT INJURY?

Most AC joint injuries are caused by trauma from contact sports. Due to the nature of its anatomy, impacting the tip of the shoulder with a high level of force can cause the supporting ligaments to sprain/tear, resulting in a separation of the joint and a potentially visible bump on the shoulder presenting. Additionally another common cause of an AC joint injury can result from repetitive micro-trauma to the joint which is usually seen in weight-liftings either over-loading by lifting too heavy a weight and/or poor technique.
