膝关节不同功能位矢状断层影像解剖学研究

Sagittal Sectional Imaging Anatomic Study of Knee Joint at Different Functional Positions

目的:观察膝关节各结构在不同功能位的断面形态变化规律,为膝关节疾患的动态MR I影像学诊断提供解剖学资料。方法:用成年男尸膝标本12例,采用低温铣切技术获取不同功能位膝关节的矢状断面解剖图像,并与相对应的动态MR I图像进行对照观测。结果:在不同功能位膝关节矢状断面与其相对应的MR I图像观察了构成膝关节的主要结构,交叉韧带、半月板及其周围软组织的形态特征、位置、毗邻及其在连续断面的变化规律。结论:膝关节的矢状断层解剖各结构形态位置及变化规律对骨科及影像学诊断和治疗有重要的价值。

Objective：To establish the sectional morphological data of knee joint at different functional positions and observe the regularity of changes on the section of knee joint＇s structures so as to provide the anatomic data for the dynamic MRI imaging diagnosis of knee joint illness. Methods：The sagittal images of knee joint at different functional positions were obtained with low temperature mill cuts technology and a comparison was made with correspondent dynamic MRI images. Results ：The morphologic features, positions and the regularity of changes in the structural components,cruciate ligament,menisci and the soft tissue around them were observed at the sagittal section. Conclusions：The structure, morphology, position and the regularity of changes of knee joint at sagittal section were valuable to orthopedic and imaging diagnosis and treatments of knee joint.
