The acromioclavicular (AC) joint is the joint where the collarbone (clavicle) meets the acromion, which is a bony projection of the shoulder blade (scapula). AC joint injuries are common, especially in contact sports such as football, rugby, and hockey.

There are three grades of AC joint injuries:
- Grade I: A sprain or partial tear of the AC ligaments.
- Grade II: A complete tear of the AC ligaments, but the clavicle does not move out of place.
- Grade III: A complete tear of the AC ligaments and the clavicle moves out of place.
The symptoms of an AC joint injury include:
- Pain in the front of the shoulder
- Swelling and bruising
- Deformity of the shoulder
- Weakness in the shoulder
If you think you have an AC joint injury, it is important to see a doctor right away. Early diagnosis and treatment can help to prevent further damage to the joint.
The treatment for an AC joint injury depends on the severity of the injury.
- Grade I injuries: These injuries can usually be treated with rest, ice, compression, and elevation (RICE). Physical therapy may also be helpful.
- Grade II injuries: These injuries may require a sling or brace to immobilize the shoulder. Physical therapy may also be helpful.
- Grade III injuries: These injuries may require surgery to repair the ligaments and/or relocate the clavicle.
Recovery from an AC joint injury can take several weeks to months. It is important to follow the doctor’s instructions carefully to ensure a full recovery.
Here are some tips to help prevent AC joint injuries:
- Warm up properly before exercising.
- Wear proper protective gear when playing sports.
- Avoid contact sports if you have a history of AC joint injuries.
