Septic arthritis of the hip caused by Yersinia enterocolitica: a case report

We report a case of bacteriologically documented hip infection caused by Yersinia enterocolitica. A 67-year-old male with a history of valvular disease was admitted for pain and motion range limitation in the left hip with a fever. No organisms were recovered by needle aspiration, but Yersinia enterocolitica grew in joint fluid obtained by surgical arthrotomy. Investigations of the gastrointestinal tract were normal, and there was no evidence of endocarditis. After 6 weeks of appropriate antibiotic therapy and immobilization with transtibial traction, the clinical and laboratory test abnormalities improved. However, the patient died from an intercurrent condition. Y. enterocolitica, a well-known cause of reactive arthritis, can cause septic arthritis.
