Sternoclavicular (SC) joint arthritis can occur at the joint between the sternum (breastbone) and the clavicle (collarbone) when the cartilage on the ends of the bones breaks down due to wear and tear or injury. The symptoms of pain and swelling may get worse with overuse and repetitive activity. The patient may experience physical limitations, swelling, and inflammation as the worn bony ends grind together.
This condition typically responds to conservative management. The use of ice, stretching, and anti-inflammatory medications can often help to reduce pain. Dr. Chudik may also perform a steroid injection to manage pain symptoms. Individual outcomes may vary depending on the severity of the arthritis. The patient will need to adjust his/her activities to avoid aggravating the joint. In general, Dr. Chudik does not recommend surgery for this condition but in rare cases it may be required.
