后路寰椎后弓螺钉内固定研究进展

寰椎后弓螺钉内固定技术的提出,为治疗枕颈部不稳提供了新的补救方法。许多文献报道了寰椎后弓螺钉固定的可行性,初步显示了其置钉点易暴露、出血少、手术时间短等优势,尤其在侧块被肿瘤、炎症、创伤等破坏无法使用寰枢关节螺钉、寰椎侧块螺钉、椎弓根螺钉时补救固定。但如果外科医生术中操作不当,则可引起医源性骨折、椎动脉及颈脊髓损伤等严重并发症。因此,寰椎后弓螺钉内固定技术的安全性和有效性成为当下研究的热点。

Progress on atlanto-axial pedicle screw fixation through posterior approach

The present of atlanto-axial pedicle screw fixation through posterior approach provide a new remedy for treating instability of pillow and cervical. A lot of researches have reported feasibility of atlanto-axial pedicle screw fixation,the results showed that it had advantages of easily exposure,less blood loss,shorter operative time,especially in treating as remedy fixation for atlanto-axial joint screw,atlas lateral mass screws and pedicle screw caused by injuries of tumor,inflammation and trauma. If not done properly,it can cause serious complications,such as iatrogenic fracture,injuries of vertebral artery and cervical spinal cord. Therefore,the safty and effectiveness of atlanto-axial pedicle screw fixation may be focus of research.
