title: Bilateral C6 spondylolysis with spondylolisthesis in 3 adolescent siblings.
abstract: BACKGROUND
  Cervical spondylolysis with spondylolisthesis is a rare condition in the pediatric population. The nature of this condition and clinical presentation are important to provide appropriate management.
  
  
  METHODS
  This is a case report of 3 adolescent siblings who had C6 cervical spondylolysis with spondylolisthesis.
  
  
  RESULTS
  Two cases were diagnosed insidiously with absence of neurological deficits and no instability on imaging and were treated conservatively. One case had a traumatic presentation associated with instability on imaging and was managed with cervical fusion and instrumentation. All 3 patients were doing well on a follow-up of >2 years.
  
  
  CONCLUSIONS
  These cases suggest that cervical spondylolysis could be familial. The treatment was offered based on clinical presentation and presence of instability on radiographic studies.
