title: Growing rod technique for the treatment of the traumatic spinopelvic dissociation: a technical trick.
abstract: BACKGROUND
  Traumatic spinopelvic dissociation, sometimes referred to as U-shaped sacral fracture, is a very rare high-energy trauma. The surgical management of spinopelvic dissociation includes decompression, reduction, and fixation.
  
  
  OBJECTIVE
  We report a novel surgical technique for the treatment of spinopelvic dissociation that uses growing rods and a pedicle screw system, which is often used to treat patients with early onset scoliosis.
  
  
  METHODS
  This case report used a technical report of spinopelvic dissociation surgery using spinopelvic fixation and the growing rod technique.
  
  
  METHODS
  One case was used as the patient sample.
  
  
  METHODS
  Radiographic outcomes, including plain X-ray, three-dimensional computed tomography, and magnetic resonance imaging scan were the outcome measures.
  
  
  METHODS
  The radiographic outcomes were compared preoperatively, postoperatively, and at the 1-year follow-up with bony union.
  
  
  RESULTS
  Growing techniques improved traumatic sacral angulation, displacement, and canal encroachment, and provided sufficient structural support.
  
  
  CONCLUSIONS
  The growing rod technique for spinopelvic dissociation under intraoperative neurophysiological monitoring could be a useful alternative surgical option, especially in patients without neurologic deficit.
