The article present results of the operative treatment of deep infections in the hip joint prostheses. Ninetieth patients treated from 1980 through 1998 were analysed. Gram-positive organisms were found in 65% of the cases and gram-negative in 35%. Staphylococcus aureus were isolated in 50% of the cases. The two-stage reimplantation procedure is performed in four patients. Excellent results were reported in three patients, and poor results in one patient. The Girdlestone pseudarthrosis as a definitive procedure is performed in fifteen patients. Good results were reported in two patients, fair results in twelve, and poor results in one patient. The mean shortening of the limb was 4.5 cm. The infection were controlled in 93% of the cases. Better functional results are obtained by the two-stage reimplantation than the Girdlestone pseudarthrosis, though is an acceptable method of controlling infection.
