  “解剖匹配”译为未确定词的双语例句
     Because that the stem of artificial joint cannot match with marrow cavity closely, the distribution of stress and load transmission is uneven. As a result, the standard artificial joint product seriation may leads to complications after operation as well as the decrease of artificial joint life.

Objective: To quantitatively analyze the normal acetabular subchondral surface and investigate its anatomic characteristics. Methods: With the aid of 3D laser surface scanner and reverse engineering technique, acetabular subchondral surface was three-dimensional reconstructed. Guided by the mathematical surface theory, the acetabular subchondral surface was then quantitatively analyzed. In the end, fitting error was statistically analyzed to validate the result by the computer optimization method. Results: The results showed that the acetabular subchondral surface belonged to the rotating elliptical sphere surface. The semi major axis was (27.22±0.31)mm long which paralleled to acetabular coronary axis, and the semi minor axis was (24.74±0.24)mm long which paralleled to acetabular arrowy axis. The rotating axis was oriented as the line passing through the right and left rotating center of femur head. The fitting error of the rotating elliptical surface was significantly less than that of the spherical surface(P<0.001). Conslusions: The acetabular subchondral 1surface was not a sphere surface but a rotating elliptical sphere surface, which curvature distribution adapted to the certain law.

目的:定量分析人体正常髋臼软骨下骨的曲面形态,探讨其解剖形态学特征。方法:采用非接触式的激光扫描,运用逆向工程技术,重建髋臼软骨下骨的三维曲面。依据数学的曲面理论,定量分析其曲面类型与曲率分布变化规律;运用计算机优化拟和算法,通过匹配误差分析,验证分析结果。结果:对53例髋臼软骨下骨曲面的测量与统计后发现,髋臼的软骨下骨曲面是一个旋转椭圆型曲面,其长轴平行于髋臼的冠状轴,长度为(27.22±0.31)mm;短轴平行于髋臼的矢状轴,长度为(24.74±0.24)mm;旋转轴位于左右股骨头旋转中心的连线上。该旋转椭圆面与髋臼软骨下骨的解剖匹配误差显著小于传统的球面(P<0.001)。结论:髋臼软骨下骨的曲率分布与变化有一定规律,髋臼软骨下骨曲面更近似于旋转椭圆曲面,而非传统所认为的简单球面。

In order to improve the precision of the current computer simulation study of hip joint,a novel acetabular surface model——a rotating ellipsoid model was developed.Based on the reverse engineering technology,the geometric information of the acetabular cartilage surface,3D point data,was acquired by 3D laser scanning.To unify the coordinates of acetabular point data,a standard coordinate system was established and the acetabular point data was then transferred to this coordinate system.The optimization method was then applied to create and validate this novel parametric surface model of acetabular cartilage.To validate the anatomic compatibility of the surface model,the anatomical fitting error,which is defined as the mean deviation distance from the surface model to the acetabular cartilage surface,was analyzed statistically.The results show that the mean anatomic fitting error of the novel model is significantly less than that of sphere model(P<0.001).The difference in anatomic compatibility between two kinds of model is that the sphere model has higher fitting error in the polar area of the acetabulum,where rotating ellipsoid model has well consistent matching.

为了提高髋关节模拟研究精度,提出一种基于逆向工程技术建立和验证髋臼软骨参数化曲面模型的新方法.首先通过激光扫描获得髋臼软骨表面完整的几何信息———点云数据;然后通过髋臼三维坐标系的建立与坐标变换,实现髋臼点云坐标的归一化;最后运用优化拟和方法建立了一种新型的髋臼软骨参数化曲面模型,并将这种新模型与传统球面模型进行了解剖匹配度(即模型与真实髋臼软骨面之间平均偏离距离)的统计分析.结果表明,新模型的解剖匹配度显著高于传统的球面模型(P<0.001),尤其在髋臼软骨的臼顶区域新模型较球面模型更具精确的解剖匹配.
