    摘要：[目的]为膝关节置换准确截骨和获得良好的下肢力线，对中原地区成人股骨干进行相关测量。[方法](1)选取47根成人正常股骨标本，拍摄正、侧位数码照片，进行定点、划线、测量五角。(2)实体上确定股骨髓内定位杆进针点的位置。[结果](1)各角度值反映了股骨远端在冠状位和矢状位的解剖形态。(2)进针点与股骨滑车中心水平距离平均为621 mm，与后交叉韧带止点前缘距离平均为670 mm。[结论](1)股骨远端1/3段与股骨近端1/3段向外侧、前侧成角，且前倾角度大于外翻角度。所以股骨远端在决定股骨髓内定位杆的位置时，冠状面上的力线对位和矢状面上的对位均很重要。(2)全膝关节置换术中确定进针点可参考股骨滑车中心和股骨髁后交叉韧带止点的位置。

    Abstract：[Objective]To measure adult normal femur specimen in order to obtain accurate femoral resection and match the distal femoral in total knee arthroplasty[Method](1)Fortyseven adult normal femur specimens of central Chinese were used for taking digital pictures in both anteroposterior and medialateral positionFive angles were measured through drawing lines of fixed point(2)The exact position of the entry point was defined by the two wires on the specimens[Result](1)The five angles reflect distal femoral anatomy features on the frontal plane and sagittal plane(2)The mean value of distance from the entry point to the center of the intercondylar notch was 621 mm and the distance from the entry point to the anterior margin of the femoral posterior cruciate ligament(PCL) insertion is found to be 67 mm[Conclusion](1)The distal onethird of femora was found to be outward bowing on frontal plane and forward bowing on Sagittal planeEspecially ......
