title: Intrapelvic Lumbosacral Fracture Dislocation in a Neurologically Intact Patient: A Case Report.
abstract: BACKGROUND
  Lumbosacral fracture dislocation is a rare entity mainly occurred in high-energy trauma accidents. In this unstable injury, anatomical separation of the spinal column from pelvis is usually associated with severe neurological deficits.
  
  
  METHODS
  We described a 16-year-old girl with extremely severe axial trauma to the lumbosacral spine who presented with fracture dislocation of the lumbosacral spine and its intrusion to the pelvic space. Despite violent lumbosacral joint dissociation on imaging studies, the patient was neurologically intact. She was treated with spinopelvic fusion and instrumentation.
  
  
  CONCLUSIONS
  Although spinopelvic fracture dislocation injuries are severe high-energy entities, in cases with traumatic spondylolytic spondylolisthesis due to widening of the vertebral canal, neurologic deficit may not be seen at all.
