title: Percutaneous Direct Repair of a Pars Defect Using Intraoperative Computed Tomography Scan: A Modification of the Buck Technique.
abstract: METHODS
  Case report.
  
  
  OBJECTIVE
  To describe a young adult with a pars defect undergoing percutaneous direct fixation using intraoperative computed tomography (CT) scan.
  
  
  BACKGROUND
  Direct pars repair has been utilized since the 1960s. There are no reports in the literature describing a percutaneous technique.
  
  
  METHODS
  Using a percutaneous technique under the guide of intraoperative CT scan, a cannulated partially threaded screw was inserted across the pars defect.
  
  
  RESULTS
  Surgery was completed without complication and the patient returned to preoperative activity level 3 months post-op. Postoperative CT scan showed a well-healed L4 pars defect.
  
  
  CONCLUSIONS
  Percutaneous direct pars repair using intraoperative CT scan offers the advantage of minimal soft tissue dissection, thereby reducing blood loss, infection risk, and recovery time.
