目的 讨论研究16层螺旋CT三维 重建应用于治疗股骨粗隆间骨折的临床 疗效与意义。方法 选取我院骨科股骨粗 隆间骨折患者100例患者进行16层螺旋CT 三维重建及X线检查。根据主要骨折数量 及骨折端稳定性、骨皮质连续性及骨折 端稳定性进行评估。结果 16层螺旋CT三 维重建所得结果与X线测量结果存在显著 差异(P＜0.05)；与手术中所测量结果更 接近，无显著差异(P＞0.05)。螺旋CT三 维重建对骨折端稳定性及骨折皮质连续 性评估与X线所得结果存在显著差异(P ＜0.05)。结论 16层螺旋CT三维重建可更 加准确的显示股骨粗隆间骨折的解剖学变 化并更好的将骨折部位情况及其稳定性、 骨折块数量进行显示。相对于常规X线检 查更具有科学性与准确性以便更好的指导 临床制定正确且具有针对性的治疗方案； 同时，为制定内固定方式或假体置换方式 提供更有利的参考依据，在一定程度上可 降低治疗及手术治疗后并发症发生风险， 对促进患者治疗及恢复具有重要意义。

Objective To discuss and study the clinical efficacy and significance of 16 slice spiral CT three dimensional reconstruction in the treatment of intertrochanteric fractures. Methods 100 cases of patients with intertrochanteric fracture of femur in our hospital were treated with 16 slice spiral CT 3D reconstruction and X-ray examination. According to the numbers of major fractures and the stability of the fracture, the continuity and stability of the fracture were evaluated. Results There were significant differences between the 16 slice spiral CT reconstruction and X-ray measurement (P<0.05).It was closer to the results of surgery, it had no differences (P＜0.05). Conclusion The 16 slice spiral CT 3D reconstruction can be more accurate to show the anatomic changes of the femoral intertrochanteric fracture and show fracture site conditions and stability, the number of fracture fragments better. Compared with the conventional X-ray examination, it is more scientific and accurate so that it can better guide the clinical setting and the treatment plan with pertinence; At the same time, it provides a reference for the development of internal fixation or replacement of prosthesis, in a certain degree, the risk of complications after treatment and operation can be decreased, it has an important significance to promote the treatment and recovery of patients
