Abstract: Objective:To study the clinical application of 16-slice spiral CT's multiplanar reconstruction (MPR) and three Dimension (3D) reconstruction images in evaluation of talus fractures.Materials and Methods:A retrospective analysis was done for 132 cases of talus fractures who received both the X-ray examination and the 16-slice spiral CT examination.Their plain films,2D trans-axial images and 3D reconstruction images of 16-slice spiral CT examination were compared and analyzed.Results:MPR and 3D images showed all of the fractures and dislocation in 132 cases.X-ray plain films showed 99 cases of fractures and 31cases of dislocation,which their detecting rate was 75% and 87% respectively.Conclusion:16-slice spiral CT images with MPR and 3D reconstruction can provide more valuable information for the clinical diagnosis and therapy of talus fractures and dislocation.
