The AC (acromioclavicular) joint makes up part of the shoulder joint. It is located where the collarbone (clavicle) meets the tip of the scapula (acromion). Arthritis is the breakdown of cartilage in a joint that results in bone spurs that cause pain, inflammation and stiffness. According to the American Academy of Orthopedic Surgeons (AAOS), AC arthritis is most likely to affect people older than 50 years of age or those who participate in athletic activities that involves stress of the AC joint. There are treatment solutions, however, that your doctor can provide to treat AC arthritis.
Medications
According to the AAOS, non-steroidal anti-inflammatory drugs, (NSAIDS) such as aspirin or ibuprofen, may reduce inflammation in the AC joint caused by arthritis. NSAIDs work by reducing chemical signals that cause inflammation. In addition, NSAIDS might relieve pain in the AC joint. Consult your doctor before taking NSAIDs if you have medical conditions that involve the liver or kidneys.
Supplements
Glucosamine and chondroitin are dietary supplements that might help with AC joint arthritis by helping to preserve the cartilage in your AC joint. Researchers, however, do not know specifically how these supplements works. Drugs.com states that glucosamine and chondroitin may not work for people with mild pain, but can be helpful in those with severe pain. Be aware that glucosamine and chondroitin is not approved by the U.S. Food and Drug Administration (FDA).
Rest and Therapy
Rest from activities that involve the affected shoulder may be beneficial. Do not use your arthritic shoulder when performing activities that cause pain. Try using your other shoulder or modify the way that you use the affected shoulder. You may also apply ice to the shoulder for 20 to 30 minutes two or three times a day, according to the AAOS. In more severe cases, your doctor may prescribe physical therapy to help you regain range of motion and function of your shoulder.
Surgery
Surgery may be necessary in more severe cases of AC arthritis. According to the AAOS, the most common procedure used to treat arthritis in the AC joint is a resection arthroplasty. This procedure involves removing a small piece of bone from the end of the collarbone. This will allow the AC joint space to widen and reduce the symptoms of AC arthritis. Most people report significant improvement after undergoing this surgery.
