Septic arthritis involving the manubriosternal joint.

Abstract

Infection of the manubriosternal joint is an exceedingly rare event. We report a case of a 38-year-old patient with systemic lupus erythematosus who developed staphylococcal septic arthritis of this joint after bacteremia. Pathogenic factors are discussed. Physicians should be aware of this unusual complication of staphylococcal bacteremia.
