The AC or acromioclavicular joint is at the front of the shoulder, at the point where the shoulder blade meets the collar bone. This joint is commonly injured in contact sports such as rugby and repeated injury can lead to the joint developing arthritis eventually. There are lots of treatments on offer at the Blackberry Clinic for AC joint arthritis including physio and osteopathy and joint injections. Here are some facts and more information about this condition for you.
Experiencing pain in the shoulder on overhead or cross body movements can be a sign you are experiencing osteoarthritis of the Acromioclavicular (AC) joint.
Most prevalent in middle aged individuals and caused by degeneration to the disc that cushions the movement of the joint.
Osteoarthritis- what happens?
Cartilage between joints breaks down, exposing bone underneath. This bone then degenerates further becoming ‘ivory-like’ and polished. Eventually bony lumps or ‘spurs’ can grow on the joint and further restrict movement.
Osteoarthritis in the AC is more likely in people who;
· Perform repetitive overhead lifting activities in their occupation or sports that stress the AC like weightlifting/rugby.
· Previous injuries to the area like sprains or dislocations and patients with a systemic arthropathy such as Rheumatoid arthritis.
Diagnosis can be made through physical examination and history taking. Often being confirmed by X-RAY/MRIs/local diagnostic anesthetic injection.
Symptoms may include:
· History of trauma to the shoulder- falling on an outstretched arm.
· Complaints of pain at night sleeping on affected side.
· Popping, clicking, grinding or catching sensation when affected shoulder is moved.
What can be done?
Management is decided by degree of pain and disability.
Conservative therapy such as Osteopathy and Physiotherapy can be offered to help with mobility, strength and lifestyle advice. It is individualized based on the grade of osteoarthritis, level of pain and functional limitations. With aims to maintain range of motion, strengthen scapular stabilizer muscles and postural corrections.
Anti-inflammatories can also be used to help with pain levels.
Local corticosteroid injections into the AC joint can also be used to provide pain relief.
