How to Tell If it Is a Separated AC Joint?

A separated acromioclavicular (AC) joint is a common injury, especially in sports. The AC joint connects the shoulder blade to the collarbone and can separate due to excessive impact, such as falling on the shoulder. Always seek immediate medical attention if you suspect that you suffered an AC joint separation. A doctor should always confirm the diagnosis so that you receive the proper treatment.

Instructions

• 1

  Assess your pain. AC joint separations typically cause moderate to severe pain at the time of injury. A sharp sensation is common when the injury first occurs, and it often changes to a dull ache over time, according to The Stretching Institute.

• 2

  Look at your shoulder in a mirror and see if you notice any deformity. While many AC joint separation injuries do not cause a change in outward appearance, you may notice a bump on your shoulder with severe injuries. Your shoulder and collarbone may also appear swollen or bruised following an AC joint separation.

• 3

  Move your arm and see if you have increased pain or loss of function. Do not try to move your arm too much if the movement causes a lot of pain. Just move your shoulder or arm slightly to help you determine if the pain is coming from the joint or the muscle.

  Visit your doctor or the emergency room so that a medical professional can assess your injury and order x-rays to examine the AC joint to determine if your injury is an AC joint separation or something else.
