ABSTRACT
[Objective]To understand the changes of periprosthetic bone mineral density(BMD) of the proximal femur in patients with failed hip arthroplasty by measuring with dual energy X-ray absorptiometry(DEXA). [Method]Periprosthetic BMD was determined in 9 patients with revision total hip arthroplasty by dual energy X-ray absorptiometry(DEXA),defining regions of interest according to Gruen(1~7),and comparing the operation side with the nonoperation side.Clinic results of the cases were evaluated according to Harris Hip Score(HHS).[Result]The mean HHS was 61 points in 9 patients at this follow-up examination.There was a significant decrease(8.9%~27.6 %) in BMD in every Gruen zone as compared with the nonoperation side.[Conclusion]The bone loss in the proximal femur in patients with failed hip arthroplasty is significant,and the pattern of bone loss around failed hip arthroplasty may be different from the typical remodeling seen after successful hip arthroplasty.
