RESUMO
At present endoprosthetics of the joints is considered as a progressive and ever developing method in the surgical treatment of patients with affection of the locomotor system of any genesis. Hence, increasing of the number of endoprosthetic results in increasing of the number of patients with periprosthetic infection. Polymorphism of the clinical picture and inspecificity of the diagnostic tests often cause a delay in the diagnosis of the joint prosthetic infection (JPI) and consequently the late treatment. The contemporary data on the etiology, epidemiology, clinical picture and diagnosis of JPI are presented. The importance of cooperated treatment of JPI, i.e. combination of the surgical management and etiotropic antibacterial therapy is indicated. The choice of the concrete treatment method is defined by the patient state, comorbid pathology, the infection severity and duration.
