The acromioclavicular joint is a joint at the top of the shoulder. It is the junction between the acromion and the clavicle. This joint can develop degenerative arthritis and osteoarthritis.
HOW IS IT DIAGNOSED?
Patients with shoulder pain due to acromioclavicular osteoarthritis can usually localize it accurately with one finger on the spot. X rays may show evidence of osteoarthritis.
WHAT ARE THE CAUSES?
This condition is more common in people who do a lot of weight lifting. It is also more common with increasing age.
WHAT ARE THE TREATMENTS?
Treatments include intra-articular injection with local anaesthetic or steroids combined with physical therapy, oral glucosamine supplements. Occasionally surgical procedures are required if conservative methods do not work.
