结论：螺旋CT三维重建量测量能明确骨折移位的程度，指导颧骨复合体手术复位，并能准确评价手术复位效果。
CONCLUSION Spiral ct three-dimensional reconstruction measurement can identify the degree of fracture shift exactly instruct and evaluate the operational restoration of zygomatic complex fractures.
结果：螺旋CT三维影像能立休、精确、多方位地显示骨折的部位、范围、移位及旋转等情况。
Result: the three-dimensional image can show the position, range, shift and rotation of the fracture, exactly and angularly.
横断面图像和MPR、MIP及VR法三维图像显示移位的上、下关节面差、不直观。
The traverse images and the images of MPR, MIP and VR showed poor dislocation.
方法对57例有移位的髋臼骨折进行术前ct三维重建，明确骨折的类型，然后制定手术方案和选择最佳的手术入路。
Methods 3d ct was performed for 57 cases of displaced acetabular fracture before operation in order to understand the fracture type, design the operation scheme and select proper operative approaches.
