AC Joint Dislocation

The acromioclavicular joint (AC Joint) is the junction between the clavicle (collar bone) and the scapula (shoulder blade).

AC joint dislocation is the damage to the ligaments of the two bones forming this joint causing the AC joint to be separated.

The dislocation occurs almost always with a fall or a high impact force onto the side of the shoulder.

What are the symptoms of AC Joint dislocation?

If you have an AC joint dislocation, you will experience:

  • Severe pain with swelling over the shoulder joint
  • Pain when raising your arm above shoulder height
  • Pain at the end of collar bone

You will probably see a prominent lump or a step-deformity where the AC joint has been disrupted.

Treatment for AC Joint Dislocation

During the acute AC joint injury, painkillers and rest are beneficial. Following this physiotherapy is often necessary to get the shoulder back to its original state.

If above treatments fail, AC joint reconstruction is likely to be recommended.

AC Joint Reconstruction

During the AC joint reconstruction, implants will be used to reduce the clavicle to the expected position.

After the surgery, the clavicle will be in place, allowing the torn ligaments to heal by themselves.
