Acromioclavicular joint arthrosis

Acromioclavicular joint is the joint between the acromion (the bone that is part of the shoulder blade) and clavicle. The destruction of cartilage that covers the surfaces of contact between these two bones leads to the acromioclavicular joint arthrosis.

Among the causes of this arthrosis, are the acromioclavicular dislocations, rheumatic and degenerative diseases.

Sometimes, the acromioclavicular joint arthrosis accompanies the subacromial impingement syndrome.

Patients cannot sleep on the affected shoulder, arm crossover (forced adduction) awakens the pain, affected area is painful to touch (local deformation occurs gradually).

An X-ray is sometimes sufficient for diagnostic. Summary may be completed with an arthrogram and MRI when researching the associated injuries.

Treatment includes painkillers and anti-inflammatory drugs, kinesiotherapy, cortisone infiltration

If symptoms are still present, we propose excision of the distal clavicle (5 mm) by arthroscopy. The intervention is performed within 1 day of hospitalization. The patient then keepshis/her arm immobilized in a sling for 2-3 weeks. Rehabilitation sessions can start a week after surgery.
