Combined Laminoplasty With Posterior Lateral Mass Plate for Unstable Spondylotic Cervical Canal Stenosis : Technical Note

概要

論文の詳細を見る
A technique of combined expanding laminoplasty using longitudinal interspinous iliac bone graft with posterior lateral mass plate is described for the treatment of cervical canal stenosis associated with spinal instability. A 52-year-old male and a 76-year-old female presented with cervical myelopathy. Imaging studies demonstrated spondylotic cervical canal stenosis associated with spinal instability. Posterior stabilization with lateral mass plate by the Axis Fixation System was performed after expanding laminoplasty using interspinous iliac bone graft. The symptoms improved and instability and malalignment (in the female patient) also improved after surgery. This combined surgical technique allows decompression of the spinal cord, immediate internal fixation by plate fixation, and subsequent long-term stabilization by interspinous bony fusion. This technique is indicated in selected patients with multiple segment spondylotic cervical canal stenosis associated with instability and/or malalignment of the spinal column for which simultaneous decompression and stabilization are required.
