No relation between general laxity and atlantoaxial instability in children with Down syndrome.
Atlantoaxial instability in children with Down syndrome (DS) may be caused by laxity of the transverse ligament. We tested the hypothesis that general laxity might predict atlantoaxial instability. General laxity and the atlantoaxial distance were assessed in 172 children with DS (aged 6-17 years; 45% girls, 55% boys). No significant correlation was noted between these two measures with either univariate or multivariate methods of statistical analysis.
