Is laminectomy and fusion the better choice than laminoplasty for multilevel cervical myelopathy with signal changes on magnetic resonance imaging? A comparison of two posterior surgeries

摘要

M, 42Y, multi-level cervical spondylotic myelopathy. Preoperative X-Ray images (A1 and A2); X-Ray images of extension and flexion (A3 and A4) shown no obvious cervical instability; Preoperative MRI scans (A5-A6) shown increased signal intensity on T2-weighted image (White arrow); Postoperative X-Ray images (A7 and A8); X-Ray images of extension and flexion at the 30 months after operation (A9 and A10) (White lines)
