UPDATES IN LAMINOPLASTY TECHNIQUES FOR TREATMENT OF MULTILEVEL CERVICAL STENOSIS

Abstract

Background: The main goal of laminoplasty is to provide decompression of the spinal cord by widening the spinal canal, and used to gain wide access to the spinal canal to perform additional procedures, e.g. adequate dissection around the dural tube, duraplasty, and removal of spinal cord tumor. Objective: Across sectional cohort study to assess effectiveness and safety of laminoplasty in treatment of multilevel cervical canal stenosis and comparison of different techniques. Patients and Methods: We studied 20 patients with multilevel cervical canal stenosis undergoing cervical laminoplasty. All patients were subjected pre-operatively to full general and neurological clinical assessment, routine laboratory work and neuroimaging by plain X-ray, CT scan and MRI cervical spine. Results: This study included 20 patients (14 males and 6 females) and the mean age was 48.9 years. There were 7 patients with history of HTN and 5 patients with history of DM.There was a significant improvement post-operatively ofNurick grade score, Japanese Orthopedic Association scores and neck pain visual analog scale score. Conclusions: Laminoplasty is becoming an increasingly popular treatment for multilevel cervical stenosis due to cervical spondylotic myelopathy. Laminoplasty minimizes the risk of certain complications associated with other surgical options, such as graft and fusion-related complications.
