Minimally invasive cervical laminoplasty versus single-door laminoplasty for treatment of cervical spondylotic myelopathy

Abstract

Abstract:

BACKGROUND: In recent years, a single-door laminoplasty for cervical spondylotic myelopathy was performed in the Department of Orthopedics, the First Affiliated Hospital of Zhengzhou University. This surgery achieved spinal decompression while remaining the important structure of cervical vertebra.
OBJECTIVE: To comparatively analyze the therapeutic effects of minimally invasive cervical laminoplasty and single-door laminoplasty on cervical spondylotic myelopathy.
METHODS: A total of 78 cases of cervical spondylotic myelopathy were randomly divided into two groups, which respectively received minimally invasive cervical laminoplasty and single-door laminoplasty.
RESULTS AND CONCLUSION: All cases were followed-up for 3-36 months. No significant difference in excellent and good rate of Japanese Orthopaedic Association score was detected between the two groups in final follow-up
(P > 0.05). The apparent rate of axial symptoms was significantly lower in the minimally invasive cervical laminoplasty group than that in the single-door laminoplasty group after treatment (P < 0.05). Cervical curvature loss was significantly lower in the minimally invasive cervical laminoplasty group than that in the single-door laminoplasty group (P < 0.05). In final follow-up, in the minimally invasive cervical laminoplasty group, two titanium screws of one patient were slightly loose, and no abnormal symptom was observed. In the single-door laminoplasty group, hinge breakage was visible in six patients. The broken vertebral plate was excised. Artificial spinal dura mater was coated on the surface of spinal cord for protection. Results suggested that the effect of two surgical methods in promoting functional recovery of spinal cord is identical. However, complications in the minimally invasive cervical laminoplasty group are further fewer than those in the single-door laminoplasty group.
