Introduction

Osteoporosis is a skeletal disorder characterized by both low bone density & micro architectural deterioration.
Prevention of osteoporotic fracture, needs paying attention to the both surrogates of bone strength.
Until recently, aBMD was the only method used in assessment of osteoporosis and fracture risk.
- more than half of the fragility fractures occurred in people with aBMD above the diagnostic threshold of osteoporosis.
TBS has recently been shown to independently predict fracture risk, to complement standard aBMD imaging.
TBS uses standard DXA spine images to measure texture in-homogeneity that is, how well-structured or poorly structured the trabecular bone appears when assessed as individual voxels and local variations in gray level distribution.
