Prevalence of Cervical Spondylolisthesis in the Sagittal Plane Using Radiographic Imaging in a Pediatric Population: A Cross Sectional Analysis of Vertebral Subluxation.

INTRODUCTION: Cervical Spondylolisthesis (CS) in children is under-studied. This cross-sectional study reports the CS prevalence in children. MATERIALS & METHODS: Subjects were selected from a private practice. Inclusion criteria: 0-17 years of age; documented demographics and health complaints; neutral lateral cervical (NLC) radiographs; and CS. Exclusion criteria: pseudosubluxation. RESULTS: 342 NLC radiographs were analyzed. 73 (21.3%) had CS greater than 2.0 mm. 42 (57.5%) had no musculoskeletal complaints. 8 (2.3%) had the presence of a CS greater than 3.5 mm. 5 (62.5%) had no musculoskeletal complaints. DISCUSSION: Pediatric populations endure various traumas. Pediatric cervical spine biomechanics has an increased risk of upper cervical spine injury. Regular spinal radiographic exams may help identify serious spinal conditions in their pre-symptomatic state. CONCLUSION: CS in pediatric populations is under-studied. CS is present in children and adolescents with and without symptoms.
