Shoulder with normal Acromion-Clavicle joint
Overview of AC Joint Injury (Shoulder)

- Pain over top of shoulder may be.
- Associated with local bruise, swelling and deformity (tenting of lateral aspect of clavicle over skin).
- Pain increases with pressure on tip of shoulder.
Physical examination of the shoulder by Dr. Abhijit Ranaware.
- X rays: Series of x-rays are needed to confirmed AC joint separation and to grade severity of injury. X-ray can also help to rule out any additional injuries to the bone, such as a fracture of the outer end of the collarbone (clavicle).

AC joint injury or separation is caused by direct hit to top of shoulder or severe traction force to upper limb.
- Direct Fall on Tip of Shoulder.
