摘要
目的:研究第4、5跗跖关节的大体解剖和影像解剖学特征,为临床诊治足部损伤提供形态学资料。方法:观察30例足骨标本的第4、5跖骨与骰骨关节面的形态特征并测量相关数据;对30侧无明显足部畸形的成人足采用16层螺旋CT行横断面、冠状面和矢状面扫描,并行三维重建;将所测得的2组数据进行统计学分析。结果:螺旋CT三维成像技术能清楚显示第4、5跗跖关节各关节面的形态结构。结论:螺旋CT三维成像技术能够帮助临床足部损伤的诊断,特别对于足外侧纵弓的整复具有重要指导意义。
Objective：To study the anatomic and CT features of the fourth and fifth tarsometatarsal joints.Methods：Thirty foot specimes taken from cadavers were randomly selected;the articular facets of the cuboid bone,fourth and fifth tarsometatarsal bones were observed and measured.As a control,thirty cases of normal adult foots underwent spiral CT（GE MEDICAL SYSTEMS Bright Speed CT16）scan with transverse and coronal and sagittal planes.With GE ADW4.2 workstations,the image data were reconstructed in 3-dimension.The structures of articular facets of the cuboid bone、fourth and fifth tarsometatarsal bones were 3D observed.After that the data were analyzed.Results：3-dimensional reconstruction spiral CT could clearly demonstrate the morphology and pattern of the articular facet of the fourth and fifth tarsometatarsal joint.Conclusion：3-dimensional reconstruction spiral CT can provide assist in diagnosis of the foot injury,especially to the guide restitution of the lateral longitudinal arcus during the operation.
