Fracture Prediction by Computed Tomography and Finite Element Analysis: Current and Future Perspectives
- 394 Downloads
Purpose of Review
This review critiques the ability of CT-based methods to predict incident hip and vertebral fractures.
CT-based techniques with concurrent calibration all show strong associations with incident hip and vertebral fracture, predicting hip and vertebral fractures as well as, and sometimes better than, dual-energy X-ray absorptiometry areal biomass density (DXA aBMD). There is growing evidence for use of routine CT scans for bone health assessment.
CT-based techniques provide a robust approach for osteoporosis diagnosis and fracture prediction. It remains to be seen if further technical advances will improve fracture prediction compared to DXA aBMD. Future work should include more standardization in CT analyses, establishment of treatment intervention thresholds, and more studies to determine whether routine CT scans can be efficiently used to expand the number of individuals who undergo evaluation for fracture risk.

Older Icelandic women who sustain incident hip fracture had deficits in the superior and inferior femoral neck cortex and the trabecular bone regions at the superior aspect of the femoral neck and the intertrochanteric region. This structural phenotype cannot be described as an accelerated pattern of normal age-related bone loss. PubMedPubMedCentralCrossRefGoogle Scholar

AUC analysis showed FN aBMD predicted hip fracture better than FN vBMD (0.76 vs. 0.72), but spine vBMD had better predictability of spine fracture than spine aBMD (0.79 vs. 0.72).
