title: [Research progress of complications of expansive laminoplasty].
abstract: OBJECTIVE
  To review the progress in the research of complications after expansive laminoplasty such as axial symptom, kyphotic deformity, and segmental motor paralysis.
  
  
  METHODS
  Recent articles about complications after expansive laminoplasty were reviewed, and comprehensive analysis was done.
  
  
  RESULTS
  The pathogenesis of axial symptom, kyphotic deformity, and segmental motor paralysis has not yet fully been understood, but has brought new finding, such as the importance of the spinous process-ligament-muscle complex, C5 palsy theory, and the involvement of the spinal cord mechanism.
  
  
  CONCLUSIONS
  The pathogenesis of axial symptom, kyphotic deformity, and segmental motor paralysis should be further investigated to prevent and treat the complications.
