What is an ACJ dislocation?
The acromioclavicular joint (ACJ) is located at the tip of the shoulder where the shoulder blade (scapula) and collarbone (clavicle) come together. These two bones are held in place by tough, sinewy tissues and ligaments, whilst there is also a pad within the joint (meniscus) that enables the bones to move on each other.
If you are experiencing severe pain, swelling or reduced mobility around your shoulder joint, this may be because the acromioclavicular joint has been damaged or dislocated. The most common causes for this type of injury tend to be as a result of direct impact on the point where your scapula and clavicle meet, often through sports or heavy labour.
Dislocated ACJ treatment
Most ACJ shoulder injuries tend to be classified as Type 1 or Type 2 injuries.
Fortunately, most of these cases will not require surgery and almost all can be managed with:
• Painkillers and anti-inflammatories
• Physiotherapy to ‘retrain’ the shoulder muscles
