Peter Hallam MS FRCS (Orth), Consultant Orthopaedic Surgeon
Acromioclavicular Joint Arthritis
Sometimes (normally from overuse) the joint between the acromion and collarbone can become arthritic. 

Symptoms
The arthritic joint produces pain around the shoulder during high, overhead activities.

Investigations
X rays and an ultrasound or MRI scan.

Treatments
Non-Operative:  Ultrasound guided injections of local anaesthetic and cortisone into the arthritic joint can reduce pain and occasionally stop any further deterioration.

Operative:  If injections fail then the arthritic joint can be removed (distal clavicle excision) either with keyhole or open surgery depending on the severity of the arthritis.
