【Abstract】 Objective To disscuss the therapeutic method of the postoperative infection after hip arthroplasty and
compare the results of one-stage revision and two-stage revision. Methods From January 1999 to December 2005, 15 casesof infection after hip arthroplasty were treated, including 10 males and 5 females, with a mean age of 63 years (54-71 years).The locations were left hip in 8 cases and right hip in 7 cases. The first operation was hip prosthesis replacement in 6 cases andtatol hip arthroplasty in 9 cases. Infection occurred after 1 month in 6 cases and after 6 months in 9 cases. The preoperativetemperature and ruting blood test were normal, the mean erythrocyte sedimentation rate(ESR) was 61 mm/h (34-80 mm/h),mean C-reactive protein(CRP) was 11.7 mg/L(5.4-21.0 mg/L). The mean Harris score was 33 (25 - 40). The X-ray films showedthat periosteal reaction, osteolysis and loosening of prosthesis occurred. The time from the first operation to revision operationwas 1-41 months (mean 7.3 months). The results of bacterial culture were positive in 11 cases. One-stage revision wasperformed in 10 ases, two-stage revision was performed in 5 cases. Results Of 15 cases, 6 were classified as early postoperativeinfection, 9 cases as late chonic infection. The microorganism cultures results of joint aspiration or pus in sinus werepositive in 11 cases and negative in 4 cases before operation and during operation; 8 had staphylococcus epidermids infection,
2 escherichia col i infection and 1 staphylococcus aureus infection. Incision of revision operation healed by first ention. Nore-infection, swell ing and tenderness occurred after 19 months (12-37 months) of follow-up. Pain of hip joint disappeared in14 cases, and only 1 case had mild pain when walking. ESR and CRP after operation decreased to normal range. The mean Harrisscore increased significantly to 84.2(79-92) after revision, showing significant difference when compared with that beforeoperation (P ＜ 0.05). Conclusion For postoperative infection after total hip arthroplasty, it is still possible to have satisfactorycl inical outcome by one-stage or two-stage revision as long as clear diaglosis and correct treatment can made.
