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.
