Hip fracture owing to osteoporosis is one of the key public health concerns specially for geriatric people, whose sufferings as well as the cost of treatment can be reduced if the fracture risk can be predicted a priori.
The current research focuses on assessing the hip fracture risk from mechanistic viewpoint. In this approach, Quantitative Computed Tomography (QCT) image based 3-dimensional FEA has been conducted to investigate the cumulative effect of anatomical variations in femur and its inhomogeneous material distribution, which varies noticeably between healthy and osteoporotic bone, and the impact load due to fall.
Primarily, a fracture risk indicator based on the ratio of bone stress to strength has been proposed to predict the hip fracture risk. At present we are trying to investiage the cumulative effect of bone microstructures to the fracture of bone at the structural level.
