AB  - OBJECTIVES: The aim of the study is to investigate the clinical and radiologic 
      factors represented by the increasing of spinal cord area associated with the 
      prognosis of the patients at long-term follow-up by multivariate analysis after 
      single-door cervical laminoplasty (SDCL). METHODS: A total of 115 patients who 
      underwent cervical laminoplasty with miniplate fixation were included from 
      November 2008 to June 2018. The average postoperative follow-up period was 17.3 
      months (range, 12-105 months). The prognosis of the patients following cervical 
      laminoplasty was evaluated by the recovery rate of Japanese Orthopedic 
      Association (JOA) at the final follow-up. The recovery rate of JOA </= 50% were 
      classified as poor prognosis group (PP group) whose prognosis is relatively poor, 
      and those> 50% were classified as good prognosis group (GP group) whose have a 
      better prognosis. The clinical factors including gender, age, duration of 
      symptoms, diagnosis type, blood loss, operative time, pre- and post-JOA score, 
      etc. were recorded. The radiologic factors including sagittal canal diameter 
      (SCD), the cervical curvature index (CCI), the range of motion (ROM), the spinal 
      canal area and the increasing of cervical spinal cord area, etc. were collected 
      before and after operation and measured by X-ray plain and computed tomography 
      (CT) scan images. The univariate analysis and multivariate logistic regression 
      analysis were performed. RESULTS: There were 62 patients in PP group and 53 
      patients in GP group. The multivariate analysis showed that the preoperative 
      (OR=6.875, P = 0.001) and postoperative JOA scores (OR=24.000, P = 0.001), 
      preoperative spinal canal area (OR=2.464, P = 0.023) and the increasing of 
      cervical spinal cord area (OR=5.438, P = 0.001) maybe related factors to the 
      recovery rate of JOA at the final follow-up. CONCLUSIONS: The preoperative spinal 
      canal area, the increasing of cervical spinal cord area, preoperative and 
      postoperative JOA scores play important roles in long-term prognosis after SDCL.
