目的 运用计算机辅助设计(computer aided design,CAD)及三维重建技术测量髋部几何解剖形态学参数,探究骨折人群股骨近端解剖形态与正常组人群(未骨折人群)的差异,分析其对髋部骨折发生率和发生类型的影响.方法 通过髋部骨折患者正常侧下肢CT扫描图像,运用Mimics 10.01软件建立三维解剖形态模型,并测量股骨颈前倾角(femoral neck anteversion angle,FNAA)、颈干角(neck-shaft angle,NSA)、股骨头直径(femoral head diameter,FHD)及股骨颈轴长(length of femoral neck axis,LFNA)等正常股骨近端三维几何解剖形态学参数.结果 股骨颈骨折组中FNAA、NSA、FHD、LFNA平均值为分别为(7.9±4.6)°、(128...

Objective To measure the hip anatomic parameters and explore the differences between the hip frac ture group and the normal group, analyze their effect on the incidence of hip fractures and fracture types by using computer aided design （CAD） and threedimensional reconstruction technique. Methods Through CT scan im ages from the lowerextremity of hip fracture patient, the 3D anatomic model was established by MimicslO. 01 software, and the 3D anatomic parameters of the normal proximal femur, namely femoral neck anteversion angle （ FNAA）, neck...
