The Problematic Sternoclavicular Joint

This report reviews conditions of the sternoclavicular joint (SCJ). The SCJ is the joint between the collarbone and the sternum or breastbone. It's the only place where there's a bony connection between the arms and the main body. All other connections are fibrous or cartilage, not bone. Problems in this joint may or may not be painful or symptomatic.

Problems at the SCJ occur more often the older we get. Arthritis (osteoarthritis and rheumatoid arthritis) is the most common condition affecting the SCJ. Infection, dislocation, and gout can also occur at this joint.

The authors present signs and symptoms and risk factors for each of these conditions. They also include some of the more rare problems that can occur such as Friedrich's disease, condensing osteitis, and cancer.

Treatment is usually for the symptoms and may include rest, anti-inflammatory drugs, or antibiotics (for infection). Surgery is rarely an option but may be needed in cases of severe pain that doesn't respond to other treatment measures.
