Abstract:
[Objective] To study the change regulatives of BMD(bone mineral density)in after total ankle arthroplasty.[Methods]From Oct.1997 to Dec.2004,the BMD of the subjects were measured to involve in the study.There were 6 cases(5 male,1 female)with an average of 54.4 years old.Their BMD of the subjects was measured by DEX-A(Lunar)at the tibia and talus of the ankle post-arthroplasty in 6 months,12 months,2 years and 3 years postoperatively.All data were saved in computer and all statistical analyses were performed uaing SPSS 8.0 system in personal computer.[Results]The bone trabecula growing into micropore coated of the prosthesis has been showed on radiograth post-surgeryat average period of 1.5 years to 2 years.In the third year itreached bone mass at the distal tibia and talus of the total ankle replacement,which mean BMD 0.854?0.217 at post operative 6 months,BMD 0.975?0.142 at post operative 12 months,BMD 0.956?0.213 at post operative 2 years,and 1.155?0.210 at 3 years(P
