【摘要】：背景:中国蒙古族人胫骨近端截骨面与国外及国内其他民族是否存在差异尚不清楚。目的:通过对蒙古族人胫骨近端截骨面各线性参数测量,分析中国北方地区蒙古族人胫骨近端截骨面解剖形态学特点。方法:CT薄层扫描38例健康蒙古族人志愿者双膝关节,扫描膝关节线上下各20 cm;原始Dicom数据导入电脑。应用Mimics软件,重建膝关节三维模型,隐藏股骨和髌骨。STL格式的胫骨三维模型图像导入3-Matic软件,显示出胫骨的正内侧面,以内侧胫骨平台最低点为基点,在内侧胫骨平台下方6 mm处,保持胫骨7°后倾角模拟全髋关节置换截骨,测量胫骨近端截骨面参数。结果与结论:①测量参数数据:健康蒙古族人志愿者38例胫骨左右侧径(79.99±3.70)mm(左),(80.25±4.01)mm(右);胫骨前后径(52.27±3.07)mm(左),(51.75±2.40)mm(右);胫骨内侧前后径(55.40±2.00)(左),(56.67±2.47)mm(右);胫骨外侧前后径(49.84±2.78)mm(左),49.58±2.80)mm(右);②测量参数差异:蒙古族人左右侧胫骨近端截骨面各线性参数差异无显著性意义(P0.05);胫骨近端截骨面内侧前后径大于外侧前后径(P0.05);男性胫骨近端截骨面各线性参数大于女性(P0.05);蒙古族人胫骨近端截骨面与部分国内外测量结果比较,各线性参数与国外及中国其他民族和地区存在一定差异;③结果证实,东西方种族间胫骨平台截骨面解剖形态学存在明显差异;中国人不同民族及地域,胫骨平台几何学参数同样可能存在差异,未来有必要应用数字骨科技术,对不同地域不同民族进行大样本数据调查和分析。
[Abstract]:Background: it is not clear whether there is a difference between the proximal tibial osteotomy of Chinese Mongolians and that of other nationalities abroad and at home. Objective: to measure the linear parameters of proximal tibia osteotomy in Mongolian. The anatomical and morphological features of proximal tibia osteotomy of Mongolian people in northern China were analyzed. Methods 38 healthy Mongolian volunteers were scanned with double knee joints with 20 cm above and below the knee joint line, and the original Dicom data were imported into computer. Mimics software was used. The 3D model of knee joint was reconstructed and the 3D images of tibia in the form of femur and patella. STL were imported into 3-Matic software to show the positive medial side of the tibia. The lowest point of the medial tibial plateau was 6 mm below the medial tibial plateau, 6 mm below the medial tibial plateau. Retaining 7 掳posterior tibia angle to simulate total hip replacement osteotomy, Results and conclusion the parameters of proximal tibia osteotomy were measured. Results and conclusions the parameters data of 38 healthy Mongolian volunteers were as follows: the left and right tibia diameters were 79.99 卤3.70 mm (80.25 卤4.01 mm), the tibial anterior and posterior diameters were 52.27 卤3.07 mm (51.75 卤2.40 mm) (right tibia); the anteroposterior and anteroposterior diameters of tibia were 55.40 卤2.00 mm (56.67 卤2.47 mm). The lateral anteroposterior diameter of the bone was 49.84 卤2.78mm (left 49.58 卤2.80mm). (2) the difference of the parameters of the right and left tibia osteotomy: there was no significant difference in the linear parameters between the left and right sides of the proximal tibia osteotomy; the medial diameter of the proximal tibial osteotomy was larger than that of the lateral anterior and posterior diameters (P0.05); the male tibia was larger than that of the lateral anterior and posterior diameters (P0.05). The linear parameters of proximal osteotomy were higher than that of female osteotomy, and the results of proximal tibial osteotomy of Mongolian people were compared with those of some domestic and international measurements. The results show that there are obvious differences in anatomical morphology of the osteotomy surface of tibial plateau between eastern and western ethnic groups, different nationalities and regions of Chinese, and different nationalities and regions of China. The geometric parameters of tibial plateau may also be different. It is necessary to use digital orthopedic technique to investigate and analyze large sample data of different regions and nationalities in the future.
