Clinical Effects of Two-Stage Revision Surgery in Treating Elderly Postoperative Infection after Total Hip Arthroplasty

Objective To evaluate the curative effect of two-stage revision of the hip joint for the treatment of elderly postoperative infection after hip arthroplasty. Methods A group of 11 patients(11 hips)above 75 years old with infections after hip arthroplasty admitted in our hospital between January 2001 and June 2008 were studied retrospectively about the clinical manifestation,treatment methods(removal of prosthesis spacer implanted during debridement in the first stage and revision of hip joint in the second stage),postoperative treatment and clinical effects. Results In the 9～42 months(average 18.5 months)′ postoperative follow-up,the mean Harris score increased significantly by 37.0,which was significantly different from preoperative score(P0.05).Infection occurred again in 1 case at the 9th month postoperatively,who was treated with Girdlestone arthrodesis at last. Conclusion Two-stage revision of the hip joint for the treatment of elderly postoperative infection after hip arthroplasty can achieve good results.
