Abstract:
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.
