- 目的：应用双能X线骨密度仪(dual-energy x-ray absorptiometry，DEXA)观察全膝关节置换后假体周围的骨密度的变化情况。Objective: To observe and analyze the change of periprosthetic bone mineral density (BMD) after total knee replacement with dual-energy x-ray absorptiometry.
- 腰椎和髋部的BMC(g)、BMD(g/cm~2)和骨大小(cm~2)均采用双能X射线骨密度仪(Dual-energy X-ray Absorptiometry,DXA)测量得到。BMC (g), BMD (g/cm~2) and bone size (cm~2) were measured at the lumbar spine and the hip region using dual-energy X-ray absorptiometry (DXA).
