【摘要】：背景:目前国内及国外膝关节的测量较多,但是关于北方局部地区尤其内蒙古地区的测量较少,局部地区胫骨平台后倾角与国人甚至国外人种的数据是否有差异目前研究较少。目的:测量蒙古族人正常膝关节胫骨内侧平台后倾角的大小,比较不同测量方法间的差异,以期得到蒙古族正常原始的胫骨内侧平台后倾角数据。方法:GE64排螺旋CT扫描60名蒙古族志愿者双膝关节的胫骨上段和股骨下段各20 cm,连续水平扫描获得数据,Mimics 16.0建立膝关节三维模型,模型经光顺、填充、分离、切割等处理,在切割后模型断面上,测量胫骨中上段前侧骨皮质延长线(A方法),胫骨骨干解剖轴(B方法),胫骨后侧骨皮质延长线的垂线(C方法)和胫骨平台上缘线的交角,得到不同测量方法的后倾角值(90°减去测得的角度)。结果与结论:①A方法测得的胫骨平台后倾角为(11.16±3.39)°,B方法为(8.60±3.29)°,C方法为(5.30±4.40)°,其中A、B方法测得结果与王业华及罗吉伟报道的数据相近(P0.05);②A,B,C方法测量所得的左侧胫骨平台后倾角度比较,差异有显著性意义(P0.05),A,B,C方法测量所得的右侧胫骨平台后倾角度比较,差异亦有显著性意义(P0.05);但左右侧别之间差异无显著性意义(P0.05);③左侧、右侧胫骨平台后倾角度分别在不同性别间比较,差异均无显著性意义(P0.05);④结果提示,蒙古族人膝关节胫骨内侧平台后倾角较小,A、B方法测得的结果与王业华及罗吉伟报道的数据近似,但胫骨平台后倾角个体差异较大,术中截骨应根据个体情况来决定。
[Abstract]:Background: there are many knee joint measurements at home and abroad, but there are few measurements in northern regions, especially in Inner Mongolia, and there is little research on the difference between tibial plateau posterior dip angle in local area and the data of Chinese and even foreign people. Objective: to measure the posterior inclination of the medial tibial plateau of the normal Mongolian knee and compare the differences among different measuring methods in order to obtain the normal original data of the posterior inclination of the medial tibial plateau. Methods the upper tibia and the lower femur of 60 Mongolian volunteers were scanned with 20 cm each of the upper tibia and the lower femur of 60 Mongolian volunteers. The 3D model of the knee joint was established by continuous horizontal scanning with Mimics 16.0. The model was treated by fairing, filling, separating, cutting and so on. On the model section after cutting, the intersections of the anterior cortical lengthening line of the middle and upper tibia, the anatomical axis B of the tibial diaphysis, the vertical line C of the posterior cortical lengthening line of the tibia were measured, and the intersection of the upper margin line of the tibial plateau was measured. The inclination of different measuring methods is 90 掳minus the measured angle. Results and conclusion the posterior inclination angle of tibial plateau measured by the 1: 1A method was 11.16 卤3.39 掳B method was 8.60 卤3.29 掳C method was 5.30 卤4.40 掳, and the results obtained by Achib method were similar to the data reported by Wang Yihua and Luo Jiwei, and the angle of left tibial plateau retroversion measured by P0.052ABBCmethod was similar to that obtained by Wang Yihua and Luo Jiwei method. There was a significant difference between the right tibial plateau tilting angle measured by P0.05AZB C method, but there was no significant difference between the left and the right side of the tibial plateau, but there was no significant difference between the left side and the right side, but there was no significant difference between the left side and the right side, but there was no significant difference between the left side and the left side, but there was no significant difference between the left and right sides. There was no significant difference in the right tibial plateau retroversion angle between the two genders. The results suggested that there was no significant difference between the two sexes. The results obtained by the small posterior inclination angle of the medial tibial plateau of the knee joint of the Mongolians were similar to those reported by Wang Yehua and Luo Jiwei, but the individual differences of the posterior inclination angle of the tibial plateau were quite large, so the osteotomy during the operation should be decided according to the individual situation.
