Morphometric analysis of the developing pediatric cervical spine.

摘要: OBJECTIVE Our understanding of pediatric cervical spine development remains incomplete. The purpose this analysis was to quantitatively define growth in a population children with normal CT scans. METHODS A total 1458 older than 1 year and younger 18 years age who had undergone scan at the authors' institution were identified. Subjects separated by sex (in years) into 34 groups. Following assignment, subjects within each group randomly selected for inclusion until target 15 been measured. Linear measurements performed on midsagittal image spine. Twenty-three unique obtained subject. RESULTS Data showed that vertical continues up boys 14 girls. Approximately 75% occurs throughout subaxial 25% across craniovertebral region. C-2 body is largest single-segment contributor growth, but vertebral bodies disc spaces also contribute. Overall childhood dependent individual as well spaces. majority spinal canal diameter 4 age. CONCLUSIONS morphometric analyses establish parameters These data should be considered when evaluating potential surgical intervention provide basis comparison studies investigating effects instrumentation fusion subsequent growth.
