A comparison, using Micro-CT, of the architecture of cancellous bone from the cervical, thoracic and lumbar spine using 480 vertebral bodies from 20 body donors

摘要

Introduction: Structure of vertebral column alters with increasing age. Material and structural properties are both important for bone strength.Despite having numerous data from thoracic and lumbar spine (TS and LS), there is a paucity of data from cervical spine (CS) relating to these parameters. We examined bone cylinders from the centres of vertebral bodies C1 to L5 from elderly subjects with respect to their bonevolume(BV/TV), trabecularthickness(Tb.Th.), separation(Tb.Sp.), trabecular orientation (SMI) and degree of anisotropy (DA).
