title: Traumatic lumbosacral dislocation: case report.
abstract: METHODS
  A case report of a bilateral lumbosacral dislocation without a fracture is presented.
  
  
  OBJECTIVE
  To report the diagnosis and treatment of a traumatic lumbosacral dislocation.
  
  
  BACKGROUND
  Lumbosacral dislocations without fractures are rare injuries, with only four cases reported in literature. The recommended treatment consists of an anterior lumbar interbody fusion after posterior reduction with pedicle screw instrumentation.
  
  
  METHODS
  The 1-year follow-up evaluation of a 17-year-old male with a traumatic lumbosacral dislocation, diagnosed with computed tomography and magnetic resonance imaging, and treated with a posterior lumbar interbody fusion procedure combined with a posterolateral fusion is reported.
  
  
  RESULTS
  At 1 year after surgery the patient is asymptomatic and has resumed his heavy manual work. Radiologic evidence of interbody fusion is present.
  
  
  CONCLUSIONS
  Lumbosacral dislocations are rare injuries. The authors demonstrate the feasibility of a posterior lumbar interbody fusion procedure in combination with posterolateral instrumentation and fusion.
