目的：探讨一次完成颈后路单开门并侧块钉固定治疗颈椎管狭窄并颈椎失稳的可行性及治疗效果。方法本组选取颈椎管狭窄并颈椎失稳患者19例，术前x线片测量均有椎管狭窄并椎体间不稳，磁共振显示脊髓受压明显；手术采用颈后路c3～7单开门减压椎管成形术，不稳节段用侧块螺钉内固定并突间关节间植骨融合术。结果术中未出现并发症，术后神经症状明显改善，拍片检查显示置钉位置正确，随诊24～36个月，平均28.6个月，侧块钉牢靠，无松动。结论完成颈后路单开门并侧块钉固定治疗颈椎管狭窄并颈椎失稳是一种简捷、可靠的治疗方法，避免了前后路联合手术，近期内疗效满意。

Objective to explore the feasibility and outcome of posterior single open-door and pedicle screw in treating canal stenosis and instability of cervical vertebrae at one time.Method the preoperative radiographs of 9 patients were measured and were diagnosed to be developmental spinal canal stenosis and instability of cervical vertebrae. Mri showed the spinal cords were compressed obviously. Posterior c3~7 single open-door decompression and canal-plasty was adopted. self-designed pedicle screws and intertransverse fusion were used in the unstable segments. Result complications were not found in the operation. the postoperative radiographs showed that the screws were in the right places. the average follow-up was 7 months, ranging from 5 to 14 months. The short-term radiographs showed ifrmly ifxed screws .Conclusion it is a simple and reliable method to treat canal stenosis and instability of cervical vertebrae at one time with posterior single open-door and pedicle screw. Anterior and posterior operations were avoided and short-term outcome was satisifed.
