DOI: 10.1007/s00198-018-4716-1
Abstract: SummaryPrior studies show vertebral strength from computed tomography-based finite element analysis may be associated with vertebral fracture risk. We found vertebral strength had a strong association with new vertebral fractures, suggesting that vertebral strength measures… read more here.
