Abstract

BACKGROUND:

Periprosthetic infection after total hip replacement is one of the most serious complications.

OBJECTIVE:

To investigate the cause of infection after total hip replacement and to review the literature of treatment strategy.

METHODS:

A retrospective analysis of pathogenic cultures on 18 infection cases after total hip replacement and review the treatment strategy.

RESULTS AND CONCLUSION:

Twenty-five (12-48) months follow-up of 18 patients after total hip replacement showed that there were six patients retained the prosthesis after debridement, five patients were preformed with one-stage revision, and among the five patients, only one case of recurrence after debridement and clear trauma again and finally the wound was healed; seven patients were preformed with two-stage revision using antibiotic bone cement and there was no recurrence in 25 months after total hip replacement; the wound of all the patients were healed completely and there was no recurrent infection in the final follow-up. The Harris score of the hip was changed from the 43.25 points preoperatively to 86.5 points postoperatively. The infected pathogenic bacteria of 18 patients after total hip replacement included six cases of staphylococcus epidermidis, four cases of staphylococcus aureus, three cases of enterobacter cloacae, two cases of pseudomonas aeruginosa, one case of hemolytic streptococcus and two cases of escherichia coli.
