Study: 'Biomechanical CT' effective for predicting hip fracture — 3 insights


A "biomechanical CT" analysis of previously acquired routine abdominal or pelvic CT scans is at least as effective as dual-energy X-ray absorptiometry testing for identifying patients at high risk of hip fracture, according to a study in the Journal of Bone and Mineral Research.

Here are three things to know.

1. In this case-cohort study, the researchers sampled from 111,694 men and women aged 65 or older who had a prior hip CT scan, a DXA within three years of the CT and no prior hip fracture.

2. The study authors then compared 1,959 patients with subsequent hip fracture with 1,979 randomly selected sex-stratified controls, analyzing their CT scans blinded to all other data.

3. Sensitivity for predicting hip fracture was higher for BCT than DXA, with comparable specificity.
