An AC joint injury, sometimes called a shoulder separation, affects the joint at the top of your shoulder where the collarbone meets the shoulder blade. This type of injury usually happens after a fall, direct blow or collision to the shoulder and is common in contact sports.
Common signs include:
- Pain at the top of your shoulder
- Swelling or bruising
- A visible bump near the shoulder
- Pain when raising your arm or moving it across your chest
How serious is it?
AC joint injuries can range from mild to more severe.
- Mild injuries may cause pain but often improve with rest and time.
- More severe injuries can affect shoulder strength and make movement uncomfortable.
What does recovery look like?
How long recovery takes depends on how significant the injury is.
- X-rays may be used to get a clearer picture of the injury.
- Treatment often includes rest, ice and wearing a sling to support the shoulder. Physical therapy may help restore strength and movement as pain improves.
- Most people recover without surgery, although more severe injuries may require further treatment.
