摘　　要：目的　探讨螺旋CT(SCT)三维和多平面重建在髋臼骨折中的临床价值。材料与方法　分析 16例髋臼骨折的轴位、多平面CT及三维CT表现。结果　表面重建 (SSD)对 14例超过 2mm的移位骨折均很好显示 ,但对于 2mm以下移位显示较差 ,多平面重建 (MPR)良好显示髋臼负重区的损伤及稳定性。结论　SCT三维重建和MPR对复杂的髋臼骨折的术前分类、指示手术入路及估计预后均有重要的临床意义。Objective To assess the clinical application of 3D (SSD) and multiplanar reconstruction (MPR) with spiral CT for acetabular fractures.Materials and Methods CT findings on axial, multiplanar and 3D images in 16 cases with acetabular fractures were analyzed.Results SSD image well demonstrated fractures displaced over 2mm in 14 cases, but was not satisfied in showing fractures displaced less than 2mm. MPR well revealed the injury of weight bearing area and the stability of acetabular joints.Conclusion Spiral CT 3D and multiplanar reconstruction play an important role in the preoperative classification of the complex acetabular fractures, and are useful for the selection of surgical approaches and for the evaluation of prognosis.
