title: Comparative analysis of curative effect of CT-guided stem cell transplantation and open surgical transplantation for sequelae of spinal cord injury.
abstract: BACKGROUND
  This study compared the clinical efficacies, advantages and disadvantages of two transplantation approaches for treating spinal cord injury: open surgical exploration combined with local stem cell transplantation (referred to as open surgical transplantation) and local stem cell transplantation by CT-guided puncture (referred to as CT-guided transplantation).
  
  
  METHODS
  The patients were divided into the following three groups to perform a retrospective controlled study: Group A included nine patients who underwent open surgical transplantation, Group B included nine patients who underwent CT-guided transplantation, and Group C included nine patients who did not receive stem cell transplantation. The Abbreviated Injury Scale (AIS), the American Spinal Injury Association (ASIA) score and the motor evoked potentials (MEP) examination were utilized to compare the differences in the clinical efficacies. The advantages and disadvantages of the two transplantation approaches were also compared, including the surgical risks, the possibility of repeating the operation, the interval between surgery and rehabilitation exercises and the scope of conditions suitable for the operation.
  
  
  RESULTS
  Whether evaluated by the AIS grading scale, the ASIA score or the MEP results, there were significant differences in the clinical efficacy among the three patient groups. Group B exhibited the best clinical outcome, followed by Group A, and Group C fared the worst. The CT-guided transplantation had the advantages of lower surgical risk, the potential to repeat the operations within a short time-frame and a short interval between surgery and rehabilitation exercise compared with the open surgical transplantation. The conditions that are suitable for CT-guided transplantation versus the conditions suitable for open surgical transplantation are not identical. The application scopes for the two approaches had their respective strengths.
  
  
  CONCLUSIONS
  CT-guided stem cell transplantation was confirmed as a safe and effective approach to treat sequelae of spinal cord injury with the advantages of simpler operation, minimal invasion, less adverse reaction and quicker recovery.
