The surgeon who treats patients with spine trauma must be able to apply a variety of management techniques to achieve optimal care of the patient. The anterior surgical approach is appropriate for some thoracolumbar burst fractures in patients with neurologic deficit and without posterior ligamentous injury. Surgery is most often indicated for patients with incomplete deficit, especially those with a large retropulsed fragment, marked canal compromise, severe anterior comminution, or kyphosis <30 degrees. This approach provides excellent visualization of the anterior aspect of the dura mater for decompression. Reconstruction of the anterior body defect can be done with autograft, allograft, or a cage. Supplementation of the graft with anterior internal fixation helps prevent kyphosis. Clinical results demonstrate improved neurologic function in most patients as well as low pseudarthrosis rates. In patients with incomplete deficit, improvement in neurologic function usually can be expected with few complications.
治疗脊柱创伤患者的外科医生必须能够应用多种治疗技术,以实现对患者的最佳治疗。前路手术入路适用于一些伴有神经功能缺损且无后韧带损伤的胸腰椎爆裂骨折患者。手术最常用于不完全性神经功能缺损的患者,尤其是那些有大的后移骨折块、明显的椎管狭窄、严重的前方粉碎或后凸畸形<30度的患者。这种入路能很好地显露硬脑膜前方以便进行减压。椎体前方缺损的重建可采用自体骨移植、异体骨移植或椎间融合器。用前路内固定补充移植有助于预防后凸畸形。临床结果显示,大多数患者的神经功能得到改善,假关节形成率也较低。对于不完全性神经功能缺损的患者,通常可预期神经功能得到改善,且并发症较少。
