Abstract

Objective To evaluate the clinical and radiological outcomes of treating patients with cervical spondylotic myelopathy (CSM) with cervical laminoplasty using the open-door technique with stabilization of titanium miniplates. Background CSM is a frequent cause of spinal cord impairment in the elderly. Cervical laminoplasty is a lamina-preserving procedure that decompresses the spinal cord with preservation of the cervical spine motion. Patients and methods This was a retrospective review of 532 patients with CSM who had open-door cervical laminoplasty from July 2015 to July 2019. Detailed history and complete clinical and neurological examinations were done. Plain radiography, computed tomography, and MRI of the cervical spine were obtained. Functional evaluation of neurological status was done using the Japanese Orthopaedic Association score. The pain intensity was evaluated using the visual analog scale. Results A total of 532 patients, comprising 345 (66.8%) males and 187 (35.2%) females, with CSM who underwent open-door cervical laminoplasty were included. The mean Japanese Orthopaedic Association score increased from 10.2 ± 1.3 (range, 9–13) preoperatively to 14.1 ± 0.9 (range, 12–16) at the end of a minimum follow-up period of 1 year, which was statistically significant (P = 0.022). Satisfactory results were achieved in 439 (82.5%) patients. The mean visual analog scale was reduced from 5.9 ± 2.3 (range, 3–7) preoperatively to 2.3 ± 3.4 (range, 0–4) at the last follow-up (P < 0.001). Conclusions Open-door cervical laminoplasty for patients with CSM has satisfactory functional and radiological outcomes.
