Infection of the sternoclavicular joint (SJI) is a rare problem accounting for approximately 1 % of cases of septic arthritis. Patients typically present with symptoms of localized pain lasting a period of several weeks with or without systemic signs of fever and chills. Confirmation is made by aspirating the joint, and broad spectrum antibiotics should be tailored to treat the identified organisms. SJI can be treated conservatively with intravenous antibiotics and repeat imaging, but surgical intervention is required if patients present with an abscess, osteomyelitis or mediastinitis.
