Abstract

Abstract: BACKGROUND: Most cervical spondylotic myelopathy with cervical curvature straight or cervical kyphosis are spinal cord line type III cervical spondylotic myelopathy. Previous studies have reported that cervical expansive open-door laminoplasty could get satisfied decompression effect of cervical spondylotic myelopathy with curvature straight or cervical kyphosis, while there is no report about the spinal cord line type III cervical spondylotic myelopathy decompression effect of cervical microendoscopic laminoplasty.
OBJECTIVE: To analyze the decompression effect and charactericstics of cervical microendoscopic laminoplasty on spinal cord line type III cervical spondylotic myelopathy.
METHODS: Totally 40 spinal cord line type III cervical spondylotic myelopathy patients (13 males, 27 females, average age of 51.6 years, average disease duration of 16.2 months, average follow-up time of 18.3 months, 55 spinal cord line type III cervical herniated discs) who underwent cervical microendoscopic laminoplasty in the First Affiliated Hospital of Zhengzhou University from February 2013 to February 2021 were retrospectively analyzed. PACS software was utilized to measure the pre-operative and last follow-up cervical magnetic resonance imaging index of the patients. The pre-operative and last follow-up herniated discs volume, cervical Cobb angle and the improved anterior spinal cord compression degree score were compared.
RESULTS AND CONCLUSION: (1) All the spinal cord line type III cervical spondylotic myelopathy obtained satisfied decompression effect. The pre-operative improved anterior spinal cord compression degree score was lower than that at last follow-up (P < 0.05). The pre-operative herniated discs volume was smaller than that at the last follow-up (P < 0.05). The cervical Cobb angle increased and cervical curvature was significantly improved (P < 0.05). (2) The results suggested that cervical microendoscopic laminoplasty which had both direct and indirect decompression effect could induce cervical herniated discs to get extensive resorption of herniated nucleus pulposus phenomenon and increase cervical lordosis. The cervical microendoscopic laminoplasty can avoid or reduce anterior discectomy in spinal cord line type III cervical spondylotic myelopathy patients and provide new strategy and basis for clinical treatment of spinal cord line type III cervical spondylotic myelopathy.
