Acromio-Clavicular (AC) Joint problems

Pain and dislocation are the two main problems that occur with the AC Joint.

Pain

Pain is felt in the region of the joint. This is usually a dull pain and at night is made worse by lying on the affected side. Sharp pain is felt when reaching overhead, particularly at the top of the reach. Symptoms of rotator cuff impingement may also be experienced.

Surgical treatment can comprise of
1. Localised Injection of Steroid and Anaesthetic Agent under Image Guidance
2. Excision lateral end of clavicle

Dislocation

Dislocation / subluxation of the joint usually occurs following a fall onto the hand or elbow or onto the point of the shoulder.
The degree of damage to the joint is classified by the joint displacement and injury to the ligaments which support the AC joint.

Treatment:

Most Grade 1,2 and 3 ACJ dislocations do not require surgery.

Most patients fully recover without any problems, however overhead athletes and manual workers may have persistent symptoms and require surgery.

Surgery is indicated if the shoulder is still painful and there is some functional loss at about 3-6 months after the injury.

Grade 4,5 and 6 injuries often require early surgical reduction and fixation.
