Abstract:
[Objective] To study the clinical results of the total hip replacement with different materials prosthesis.[Methods]Eighty-five patients(nighty-two hips)undergoing total hip replacement were enrolled in this study.Through X-ray examination,the stress force of different material prosthesis on the proxmial femur and periaccetabular bone was observed.[Results]There were no clinical signs of the loose or bone absorption around the prostheses in all patients.Debris reaction was found in the metal-polyethylene group and ceramic-polyethylene group,not found in the metal-metal group and ceramic-ceramic group.[Conclusion]The stress force between different material prostheses and bone interface was not significantly different.Bone osteolysis doue to wear of polyethylene prosthesis is the key factor for the long-term outcomes of the total hip replacement.In addition,it is correlated with prosthesis manufacture,bone quanlity and surgical technique.
