Extended-spectrum β-lactamase-producing Escherichia coli rib osteomyelitis with debridement and vacuum-assisted closure.

Rib osteomyelitis is a rare disease, comprising 1% or less of all osteomyelitis. Treatment of rib osteomyelitis includes prolonged antibiotic therapy and surgical intervention. Indications for surgical treatment of rib osteomyelitis remain unclear, however, because of few reported cases. We report the first known case of extended-spectrum β-lactamase-producing Escherichia coli rib osteomyelitis caused by urosepsis. The 69-year-old male patient remains free of recurrence and symptoms after rib resection and vacuum-assisted closure treatment with antibiotic therapy. Rib osteomyelitis should be considered as differential diagnosis when patients report chest pain after bacteraemic infection. We recommend surgical treatment for patients with drug-resistant bacterial rib osteomyelitis.
