AC Joint Dislocation & Reconstruction

Guidelines for patients following Modified Weaver-Dunn procedure

for Reconstruction of the Acromioclavicular joint

Introduction

The Acromioclavicular joint (ACJ) is part of the shoulder complex. It is situated on

top of the shoulder joining the clavicle (collar bone) to the scapular (shoulder

blade).The joint can be separated (dislocated) as a result of injury. Ligaments are

torn and in severe cases surgery is required to stablise the joint.

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.

Complications

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.

GENERAL GUIDELINES

Pain

A nerve block may be used during the procedure, which means that immediately

after the operation the shoulder and arm can feel numb for a few hours. The

shoulder will be sore when this wears off and this may last for the first few weeks.

It is important that you continue to take the painkillers. Ice packs may also help

reduce pain. Wrap frozen peas/crushed ice in a damp, cold towel and place on the

shoulder for up to 15 minutes.

Wearing a sling

You will return from theatre wearing a sling with a body belt. It should be worn

under your clothes for three weeks. Only very gentle movements will be allowed

under the guidelines of your physiotherapist i.e. for hygiene. After three weeks the

body belt will be removed and you will continue to wear the sling over the clothes

for a further three weeks. At this time you will start formal physiotherapy.

The wound

Open repair: there is an incision of 5cms over the top of the shoulder. The stitch is dissolvable but may require trimming at 3 weeks. Keep the wound dry until it is well healed.

Arthroscopic (keyhole) repair: This keyhole operation usually done through five to six 4mm puncture wounds. There will be no stitches; only small sticking plaster strips over the wounds. These should be kept dry until healed. This usually takes 5 to 7 days.

If your wound changes in appearance, weeps fluid, pus, or you feel unwell with a high temperature, contact immediately your GP.

Posture

Before starting any activity/exercise it is important to position your shoulders

correctly. This allows normal shoulder function. Gently move your shoulder blades

down and in towards the spine but not in a braced back position.

Driving

You will not be able to drive for a minimum of 8 weeks. Your surgeon will confirm

when you may begin.

Returning to work

This will depend upon your occupation. You will need to discuss this with your

surgeon. Remember you will be completely one-handed for the first 6

weeks and all movements or activities above shoulder level should be

avoided for at least 12 weeks from your operation.

Leisure activities

Your physiotherapist and surgeon will advise you when it is safe to resume your

leisure activities.

Follow up appointments

You will be asked to make an appointment to be reviewed at The Shoulder Unit

approximately three weeks after your procedure. You will be reviewed by your

surgeon/specialist physiotherapist who will check your progress.

Progression

This is variable. Following discharge your pain will slowly decrease and you will

become more confident. After 6 weeks your physiotherapist will guide you through

an appropriate exercise programme to help you regain full function.

Exercises

You will perform only elbow, wrist and hand exercises for the first 3 weeks.Your

physiotherapist will teach you the following excursuses.

1. Keep your arm in the sling and move your hand up and down at the wrist.

2. With your arm in the sling and the elbow bent at your side, turn the hand to

face the ceiling and then the ground.

3. With arm in the sling regularly shrug shoulders up and down and circle

forwards and backwards

4. In sitting, take your arm out of the sling, bend and straighten the elbow on to

your lap.

Repeat each exercise 10 times hourly. Continue these exercises until otherwise

advised by your physiotherapist.
