Application of non-cement femoral stem in total hip revision

Objective To assess the application of non-cement femoral stem prosthesis in total hip revision. Methods The clinical and radiographic outcomes in 18 patients(10 males and 8 females) aged 45-76 years(mean 58 years) after total hip revision with non-cement femoral prosthesis from January 2008 to November 2011 in our department were assessed.Ten patients underwent total hip revision due to infection of the prosthesis and 8 patients underwent total hip revision due to aseptic loosening of the prosthesis.The patients were scored according to the Harris scoring scale and their hip joint underwent anterioposterior and lateral X-ray examination before and after operation. Results The patients were followed up for 6-42 months(mean 30 months).The Harris score was 39(23-53) before operation and was 92(84-96) at the last follow-up.The patients could walk without crutch and their hip pain was alleviated 2-3 months after operation.Only one patient complained of uncomfortable feeling and mild pain in her lateral hip,which were dismissed after having 75 mg difene,once a day for two weeks.The femoral stem prosthesis grew into the hip at the last follow-up with no significant complication.Dislocation found in one patient 2 weeks after operation was fixed with cast for 6 weeks.The patient was followed up for 6 months,during which no dislocation occurred. Conclusion Non-cement femoral stem prosthesis is a good choice for total hip revision with satisfactory short-term clinical and radiographic outcomes.
