【摘要】：目的:确定利用mimics三维重建技术研究股骨颈截面的方法,得到股骨颈的截面并在坐标系中描绘出来。方法:1.选取山东中医药大学附属医院2010年10月~2015年10月时间段内扫描得到的髋关节CT数据,遴选65周岁以下、右髋部无明显骨伤骨病的男性病例30例。2.应用mimics软件重建右侧股骨近端的三维模型,应用Murphy定轴法在三维空间确定股骨头颈轴,并垂直于头颈轴重新切割,得到股骨颈横截面。3.以头颈轴重合点为原点,以原点与股骨大粗隆连线作为x轴建立坐标系,并在坐标系中将得到的股骨颈截面描绘出来。4.测量所得图形的长轴和短轴,用于描述所得截面图形。结果:1.得到股骨颈截面的形状,并在坐标系中描绘出来。整合图像最小长轴((?)±S):34.46±1.93mm,最小短轴((?)±S):27.17±1.74mm。2.截面形状接近三角形。结论:1.确定了应用mimics三维重建技术研究股骨颈截面的方法。2.股骨颈截面是一个斜行的接近于三角形的形状。3.建立的坐标系能够直观表达股骨颈截面的情况。4.为内固定三维定位打下了一定的基础。
[Abstract]:Aim: to determine the method of using mimics 3D reconstruction technique to study the femoral neck section, and to obtain the femoral neck section and describe it in coordinate system. Method 1: 1. The CT data of hip joint from October 2010 to October 2015 in affiliated Hospital of Shandong University of traditional Chinese Medicine were selected to select 30 cases of male under 65 years of age with no obvious bone injury in right hip. The mimics software was used to reconstruct the 3D model of the proximal end of the right femur. The neck axis of the femoral head was determined in three dimensional space by Murphy fixed axis method, and the cross section of the femoral neck was obtained by recutting the neck axis perpendicular to the head and neck axis. Taking the coincidence point of the head and neck axis as the origin and the line between the origin and the great trochanter of the femur as the x-axis, the coordinate system is established, and the section of the femoral neck obtained in the coordinate system is described as .4. The long axis and short axis of the measured figure, used to describe the resulting cross-section pattern. The result is 1: 1. The shape of the section of the femoral neck is obtained and described in the coordinate system. The minimum long axis of the integrated image was (34.46 卤1.93 mm) 卤Sch: 34.46 卤1.93 mm, and the minimum short axis was (27.17 卤1.74 mm 路2). The shape of the section is close to the triangle. Conclusion 1. The method of using mimics 3D reconstruction technique to study the femoral neck section was determined. 2. 2. The section of the neck of the femur is an oblique shape close to that of a triangle. The coordinate system established can express the femoral neck section directly. 4. It lays a foundation for three-dimensional positioning of internal fixation.
