Klebsilla pneumoniae is the very rarely cause of osteomyelitis in adults, most commonly in the immunocompromised patients with extra-sceletal infections. Successful therapy of chronic refractory osteomyelitis included different orthopaedic methods of treatment, the long time antibiotics therapy and more and more freaquently treatment with adjuvant hyperbaric oxygenation. We report an uncommon case of patient with chronic postraumatic osteomyelitis cased by dissemination of Klebsilla pneumoniae from urinary tract to place of osteosinthesis of femur. Treatment of this case of chronic refractory Klebsilla osteomyelitis finished successfuly after treatment with hyperbaric oxygenation two years from start of desease.
