AB  - BACKGROUND Many clinical studies have assessed the association of laminoplasty 
      opening size (LOS) with sagittal canal diameter (SCD) based on single-door 
      cervical laminoplasty (SDCL). Nevertheless, the "worn-off" lamina extracted in 
      SDCL was neglected in these reports. We aimed to develop a simple mathematical 
      model to analyze the relationship between the effective LOS and SCD, taking into 
      consideration the worn-off lamina. MATERIAL AND METHODS A total of 106 patients 
      treated by SDCL at our hospital were included in this study. Pre-operative and 
      post-operative SCDs were assessed using a picture archiving and communication 
      system (PACS) based on computed tomography scans. Mini-plate sizes as well as 
      drill bit diameters were recorded in detail in order to determine the effective 
      LOS for each vertebral lamina involved. RESULTS SCD in all patients was increased 
      significantly after SDCL (P<0.01). A linear correlation was found between 
      effective LOS and the post-operative SCD increment from C3 to C7 (R(2)>0.933, 
      P<0.001). The 12 mm mini-plate was most often used in SDCL, accounting for 64.45% 
      of all cases, whereas 10 mm and 16 mm mini-plates were the least used, accounting 
      for 3.85% and 3.00%, respectively. CONCLUSIONS There is a strong linear 
      correlation between effective LOS and the post-operative SCD increment. The SCD 
      was increased by about 0.5 mm per mm increase in effective LOS. Thus, 
      post-operative SCD could be precisely calculated and predicted, enabling the 
      selection of optimal mini-plate prior to SDCL.
