Educational Pearls:

• Septic arthritis of the sternoclavicular joint is uncommon accounting for
• Immunosuppression and IV drug use increases the risk
• Can account for up to 17% of septic arthritis cases in patients who use IV drugs
• Symptoms are typically vague with pain presenting around where the sternum meets the clavicle
• Consider imaging with CT or MRI and draining/analyzing the fluid if possible
• Antibiotics are the mainstay of treatment, but surgery may be required to wash out joint and resect infected bone
• As septic arteritis of the sternoclavicular join is uncommon, remember that patients presenting multiple times for the same complaint require a broader differential and a more extensive workup so that less common conditions are not missed
