ABSTRACT

ObjectiveTo explore the effect of second-stage revision in treating infection after artificial total hip arthroplasty.MethodsThe clinical data of 11 cases with infection after artificial total hip arthroplasty who got second-stage revision from April 2007 to October 2009 were analyzed retrospectively.All patients were treated with first-stage complete debridement,antibiotic-loaded bone cement prosthesis implantation and second-stage revision after controlling infection.The therapeutic effect was assessed by Harris hip score,laboratory examination and imaging study.ResultsThe average interval of first-stage debridement and second-stage revision was 5.6 (4-11) months.The average time of follow-up was 34 (24-48) months.None of 11 patients had reinfection and complications.Harris hip score before operation [17-43 (30.71±13.52) scores] and during follow-up after operation [72-96 (84.38±12.85) scores] had statistical significance (P＜ 0.05).Six cases had good effect,4 cases were moderate and 1 case was acceptable.The rate of good and moderate effect was 90.91％( 10/1 1 ).ConclusionsSecond-stage revision can reserve the function of hip joint effectively and has high infection eradicating rate.Therefore,it is an effective treatment for postoperative infection of artificial total hip arthroplasty.
