Clinical value of multiplanar reconstruction(MPR) and three-dimensional reconstruction using multislice spiral computed tomography(MSCT) in complex acetabular fractures

Objective:To discuss the clinical value of multislice spiral CT(MSCT) multiplanar reconstruction(MPR) and three-dimensional reconstruction in complex acetabular fractures.Methods:The performance of MPR,surface shaded display(SSD) and volume rendering(VR) of 36 patients complex acetabular fractures were analyzed retrospectively.Results:On MPR,SSD and VR,36 cases of complex acetabular fractures and 16 cases of femoral head dislocation were demonstrated,and 51,43,46 fractures of other bones in pelvis were demonstrated by MPR, SSD,VR respectively.MPR and VR demonstrated one case of small bone fragments in acetabulum which cannot be displayed by SSD.MPR were superior than SSD,VR showing direction and quantity of acetabular fracture alignment.While SSD,VR were stereoscopic and accurate in showing space position,and better than MPR in the classify of complex acetabular fractures and judgment of the direction of femoral head dislocation.Conclusion:A combination of MSCT 3D images with MPR and axial tomography could stereoscopically and clearly demonstrate the space position of complex acetabular fractures and joint dislocation,which is helpful for clinical diagnosis and treatment.
