Sternoclavicular septic arthritis in a previously healthy patient: a case report and review of the literature.

Sternoclavicular septic arthritis is an unusual event in healthy patients. Cases have been reported in diabetes mellitus patients, intravenous drug abusers and patients affected by rheumatoid arthritis. We report a case of this unique infection that occurred in a patient who was not at risk of septic arthritis. Through this case and a review of the literature, we discuss the difficulty of diagnosing this disorder, and the consequences of delayed treatment in terms of life-threatening outcomes and therapeutic options.
