The work presents the results of the treatment of 6 patients with periendoprosthetic hip infection with the use of the spacer in the Orthopaetic-Traumatic Ward between 01. 09. 2010 and 31. 12. 2013. Each case of infection was treated in two stages. In the first stage, the primary endoprothesis and inflammatory site were removed, and SPACER was implanted. In the second stage, after subsidence of clinical and laboratory symptoms of infection, the surgery was performed involving exchange of the SPACER to a revisory endoprothesis . All the patients were administered Vancomicine intravenously from the day of surgery until the results of bacterial culture were obtained. Then the antibiotic was given intravenously according to the antibiogram for 10 days; in case of negative culture, the therapy with Vancmicinewas continued for 10 days. This was followed by the administration of an oral antibiotic according to antibiogram for 6 weeks, and in case of negative culture, Biseptol 2 x 960 mg was given also for 6 weeks. The second stage of the procedure was carried out between the third and sixth month after the first surgery. In 5 patients inflammatory condition subsided, and a functional result was assessed by the patients as good. In one case inflammation did not heal and the patient remains with "hanging hip"; the result of the treatment was assessed as bad.
