AB  - OBJECTIVES: To explore the factors associated with the increased spinal cord area 
      in single-door cervical laminoplasty (SDCL) with miniplate fixation. METHODS: A 
      retrospective study enrolled 83 patients underwent SDCL with miniplate fixation 
      and the patient characteristics such as age, gender, tobacco use, alcohol use, 
      diabetes mellitus, hypertension, diagnosis, operative level, etc., were obtained. 
      The opening angle, door shaft position and spinal canal area of the patients were 
      measured after surgery. The sagittal canal diameter (SCD), the C2-7 Cobb angle, 
      the cervical curvature index (CCI), the range of motion (ROM) and the spinal 
      canal area were measured before and after operation. The increased cervical 
      spinal cord area was also measured before and after surgery, and the correlation 
      between the above indicators and the increased cervical spinal cord area was 
      studied through Pearson's correlation analysis and multivariate logistic 
      regression analysis. RESULTS: There were 34 patients in small spinal cord area 
      increment group (SAI group), 29 patients in middle spinal cord area increment 
      group (MAI group) and 20 patients in large spinal cord area increment group (LAI 
      group). The preoperative diagnosis(P = 0.001), door shaft position (P = 0.008), 
      preoperative spinal canal area (P = 0.004) and postoperative spinal canal area 
      (P = 0.015) were significant different among the 3 groups. The multivariate 
      analysis showed that the preoperative diagnosis (OR = 2.076, P = 0.035), door 
      shaft position (OR = 3.425, P = 0.020) and preoperative spinal canal area 
      (OR = 10.217, P = 0.009) were related to increased spinal cord area. CONCLUSIONS: 
      The preoperative diagnosis, door shaft position and preoperative spinal canal 
      area might be associated with increased spinal cord area after cervical 
      laminoplasty with miniplate fixation. Preoperative symptoms are mostly caused by 
      compression of the spinal cord, so spinal cord area enlargement can bring a 
      better recovery in patients alongside long-term. Spine surgeons should pay more 
      attention to the accuracy of the preoperative diagnosis, the preoperative 
      measurement of spinal canal area and the door shaft position during the 
      operation.
