摘要：

背景：有研究表明股骨远端微创锁定内固定钢板治疗股骨远端骨折具有较好的疗效，但其设计参数多为参照西方人种数据，且其产品规格有限。
目的：对成年中国人中远端股骨微创锁定内固定钢板手术相关解剖CT数据进行数字化测量。
方法：选自内蒙古医学院第二附属医院影像科非膝关节疾患的成人CT连续扫描数据15例，利用Mimics 10.01软件进行三维重建，在三维立体图形中测量股骨远端宽；股骨外侧髁前后径；股骨外侧髁基底部宽；股骨外侧髁干角；自股骨大转子下缘5 cm至外上髁每隔5 cm划分为1段，共分为5段，分别测量每段中部股骨内外侧皮质及髓腔横径。
结果与结论：成年中国人中远端股骨微创锁定内固定钢板固定后，股骨远端左右侧宽分别为(84.80±1.27) mm和(84.60± 1.40) mm；股骨外侧髁前后径分别为(67.36±1.41) mm和(66.27±1.42) mm；股骨外侧髁基底部宽分别为(42.53±3.42) mm和(42.98±1.25) mm；股骨外侧髁干角分别为(7.58±0.69)°和(7.66±0.79)°，左右侧别间差异均无显著性意义。

Abstract:

BACKGROUND: The research has shown that the less invasive stable system (LISS) fixation has good effect on the treatment of distal femoral fractures, but its parameter was according to westerner, and the specification of a manufactured item is limited. 
OBJECTIVE: To digital measure the related anatomical CT data of LISS fixation in Chinese adults. 
METHODS: Fifteen cases imaging samples with no disease or osteoporosis were selected from the Second Affiliated Hospital of Inner Mongolia Medical College. The MIMICS10.01 software was used to do the three-dimensional reconstruction, the width of distal femur, anteroposterior diameter of condylus lateralis femoris, basilar part width of condylus lateralis femoris and angle between condylus lateralis femoris and trunk were measured in the three-dimensional images. Every 5 cm was divided into a segment from the 5 cm to the lower edge of the greater trochanter to the lateral epicondyle, five segments in total. The width of internal and lateral cortex and medullary cavity diameter of the femur in the central part of each segments were measured.  
RESULTS AND CONCLUSION: After LISS fixation in Chinese adults, the width and anteroposterior diameter of condylus lateralis femoris were (84.80±1.27) mm and (67.36±1.41) mm in the left and (84.60±1.40) mm and (66.27±1.42) mm in the right; the basilar part width of condylus lateralis femoris was (42.53±3.42) mm and (42.98±1.25) mm; the angle between condylus lateralis femoris and trunk was (7.58±0.69)° in the left and (7.66±0.79)° in the right, and there was no significant difference between two sides.
