AC Joint Dislocation Reconstruction [Shoulder]

The operation

The Modified Weaver-Dunn procedure involves utilising sound ligaments (Coraco Acromial Ligament) to reconstruct and stabilise the joint. This reconstruction is supported by an absorbable cord.

The operation can be performed using mini-open surgery through small 5cm incision over the top-front of the shoulder, or through keyhole surgery using 5-6 4mm stab incisions. The surgeon will suggest the most suitable technique for you.


As with all surgery there is a risk of some complications. These are rare, but you should be aware of them before your operation.

They include:

  • Complications relating to the anaesthetic.
  • Infection.
  • Failure to achieve successful result.
  • A need to redo the surgery.
  • Injury to the nerves or blood vessels around the shoulder.
  • fracture
  • Prolonged stiffness and or pain.
  • Implant failure
  • Re-tear of the ligaments.

If you require further information please discuss with the doctors either in clinic or on admission.

You will usually be in hospital either for a day or overnight. A doctor/physiotherapist will see you prior to discharge and you will be taught exercises to do and given further advice to guide you through your recovery.
