Data was collected by researching medical cards and medical information system, examination of patients in the outpatient clinic, phone communication and e-mail. Results and discussion: We have treated 449 patients with hip periprosthetic infection. The average age of patients was 55,6±12,6 years(Ме -57, CI 54,4; 56,8) and turned out to be significantly younger than the mean age in well-noun national registers and 66%(n=277) were male. In more than 90% (n=407) of cases, infection was classificated as cronic (more than 3 weeks after manifestation), 76,8% (n=345) of patients had open sinus tract to the prosthesis. Our results have a significant difference from Australian register, as only 21 % of patients in Australia have a sinus or time after manifestation of symptoms for more than 30 days.
