    [Abstract] Objective To investigate the value and security of improved open-door posterior cervical laminoplasty in treating cervical spondylotic myelopathy (CSM) with cervical spinal stenosis patients. Methods Selected 35 CSM with cervical spinal stenosis patients to treat with improved open-door posterior cervical laminoplasty. Compared JOA scores of preoperative and postoperative to assess the clinical efficacy. Results Compared with preoperative, JOA scores of postoperative significantly increased, and the difference was statistically significant (P<0.05). Conclusion Improved open-door posterior cervical laminoplasty in treatment of CSM with cervical spinal stenosis is effective and safe. ......
