Abstract:
[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 15 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 C_(3~7) 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 after the operation.The postoperative radiographs showed that the screws were in the right places.The average follow-up time was 13 months,ranging from 7 to 18 months.The short-term radiographs showed firmly fixed 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 have been avoided and the short-term outcome is satisfied.
