Spinal canal narrowing as a result of retropulsion of spinal structures before or during cement augmentation has been considered a contraindication to therapy. The authors describe three cases of compression fractures safely treated with cement augmentation with the novel application of C-arm cone-beam computed tomography (CT). All cases involved small amounts of posterior cement extrusion, after which osteotomy needles were left in place during C-arm cone-beam CT. Rapidly reformatted images were viewed with the use of bone windows, yielding three-dimensional visualization of pertinent anatomy to confirm endpoints of posterior extrusion and adequate bone filling.
在骨水泥强化之前或期间，脊柱结构后凸导致的椎管狭窄被视为治疗的禁忌证。作者描述了3例通过新型C形臂锥束计算机断层扫描（CT）应用骨水泥强化安全治疗的压缩性骨折病例。所有病例均有少量骨水泥向后挤出，之后在C形臂锥束CT检查期间保留截骨针。使用骨窗观察快速重建的图像，从而对相关解剖结构进行三维可视化，以确认骨水泥向后挤出的终点和充分的骨填充情况。
