Resumen:
BACKGROUND CONTEXT: To date, no information about the cortical bone
microstructural properties in atlas vertebrae with posterior arch
defects has been reported.
PURPOSE: To test if there is an increased cortical bone thickening in
atlases with Type A posterior atlas arch defects in an experimental
model.
STUDY DESIGN: Micro-computed tomography (CT) study on cadaveric atlas
vertebrae.
METHODS: We analyzed the cortical bone thickness, the cortical volume,
and the medullary volume (SkyScan 1172 Bruker micro-CT NV,Kontich,
Belgium) in cadaveric dry vertebrae with a Type A atlas arch defect and
normal control vertebrae.
RESULTS: The micro-CT study revealed significant differences in cortical
bone thickness (p=.005), cortical volume (p=.003), and medullary volume
(p=.009) values between the normal and the Type A vertebrae.
CONCLUSIONS: Type A congenital atlas arch defects present a cortical
bone thickening that may play a protective role against atlas fractures.
