Objective:To report the results of treatment of cervical spondylotic myelopathy(CSM) by expansive open door laminoplasty with reconstruction of spinous process.Method:21 cases of CSM combined with cervical spinal stenosis were reviewed.16 of them were male and 5 were female,with an average age of 49 years.All of them were treated by expansive open door laminoplasty with reconstruction of spinous process.21 cases had been followed up for an average of 2 years and 6 months.Result:JOA recovery rate was 76.3%.Instability of the cervical spine and reclosed open-door and anomaly of turn over flexion of cervical spine were not found.Conclusion:Expansive open door laminoplasty with reconstruction of spinous process for CSM is good and stable.To reconstructe spinous process with muscle pedicle may be an efffective measure to prevent cervical deformity and instability after expansive laminoplasty.
