【摘要】：背景:针对髋臼前柱合并四边体骨折,是否存在一种前柱四边体翼型钢板同时解决钢板术中多次塑性和四边体内移等问题呢?目的:探讨Mimics软件在髋臼前柱四边体翼型钢板-四边体挡板的设计和解剖学参数测量中的作用。方法:采用Mimics软件对共60例正常骨盆CT数据进行三维重建,测量钢板四边体挡板设计所需要的各解剖参数,包括弓状缘平面-四边体平面夹角、四边体各边界、髋臼四边体骨质厚度等。绘制髋臼在四方区骨面投影线和四边体置钉危险区,在四边体危险区以外区域寻找并设置进钉点,测量挡板螺钉的安全进钉角度。结果与结论:(1)弓状缘平面-四边体平面夹角男女之间比较差异无显著性意义;(2)男性骨质最薄厚度值显著大于女性;(3)男性四方区挡板螺钉P1螺钉最大内倾角和P2螺钉最大内倾角显著小于女性;P3螺钉最大内倾角男女差异无显著性意义。(4)结果说明,设计研发髋臼前柱四边体翼型钢板-四边体挡板可利用Mimics软件测量骨盆髋臼解剖学数据,方法简便、易行、直观;根据髋臼前柱和四边体骨面特征新定义的解剖学参数可恰当描述髋臼四边体的解剖学共同特征和差异。
[Abstract]:Background: in view of acetabular anterior column combined with quadrilateral fracture, is there a kind of front column quadrilateral airfoil plate which can solve the problems of multiple plasticity and internal displacement of the four sides in the steel plate at the same time? Objective: to investigate the effect of Mimics software on the design and anatomical parameter measurement of the quadrihedral flange plate of acetabular anterior column. Methods: 60 cases of normal pelvic CT data were reconstructed by Mimics software. The anatomical parameters needed for the design of the steel plate quadrilateral baffle are measured, including the angle between the arcuate edge plane and the quadrilateral plane, and the boundaries of the quadrilateral body. Acetabular tetrahedral bone thickness and so on. The acetabular projection line on the bone surface and the dangerous area of the tetrahedral nailing are drawn, and the nail points are found and set outside the tetrahedral area. The angle of safe entry of baffle screws was measured. Results and conclusions there was no significant difference between male and female in the angle between arcuate margin plane and quadrilateral plane. (2) the thinnest thickness of bone in male was significantly greater than that in female. The results showed that the maximum inclinations of plate screws P1 screws and P2 screws were significantly lower than that of female P 3 screws. The Mimics software was used to measure the data of acetabular anatomy of the pelvis. The method was simple, easy and intuitionistic. The common anatomical characteristics and differences of acetabular tetrahedron can be properly described according to the newly defined anatomical parameters of acetabular anterior column and tetrahedral bone face.
