Trabecular bone microstructure can vary significantly within a single specimen, challenging traditional morphometric indices. New methods are needed to predict bone failure in inhomogeneous bone samples, as conventional measures may not capture critical failure mechanisms.

Area of Science:

  • Biomedical Engineering
  • Orthopedic Research
  • Materials Science

Background:

  • Morphometric indices are commonly used to predict trabecular bone failure.
  • These indices often assume homogeneity within bone specimens, which may not reflect reality.
  • Significant variance in bone volume fraction (BV/TV) can exist within a single bone sample.

Purpose of the Study:

  • To assess the limitations of conventional morphometric indices in predicting bone failure in inhomogeneous specimens.
  • To investigate the relationship between microstructural variations and bone failure mechanisms.
  • To explore the need for novel indices for predicting failure in non-homogeneous bone.

Main Methods:

  • Harvested 13 cadaveric human spine samples.
  • Utilized image-guided failure assessment (IGFA) combining microcompression and micro-computed tomography (µCT).

  • Calculated morphometric indices for entire samples and subregions.

    • Main Results:

    • Bone volume fraction (BV/TV) showed significant intra-specimen variance (CV 9.07%–28.23%).
    • Ultimate strength prediction was comparable using whole-sample BV/TV (R²=0.55) and weakest subregion BV/TV (R²=0.57).
    • Identified distinct failure mechanisms in homogeneous versus inhomogeneous bone, with catastrophic failure in inhomogeneous samples linked to single trabecular defects.

    Conclusions:

    • Conventional morphometric indices may be insufficient for predicting bone failure in inhomogeneous trabecular bone.
    • The failure mechanism in inhomogeneous bone, driven by localized defects, is not captured by current methods.
    • Novel morphometric indices are required to accurately predict failure in heterogeneous bone microstructures.
