fracture threshold

fracture threshold

a measure of bone density used in predicting osteoporosis risk factors. Various investigators have established different methods of interpreting bone density data. One method predicts that 95% of women will have vertebral fractures if their trabecular bone volume is less than 14% of the mean.

The presence of portable and cost effective measuring tools for the diagnosis of osteoporosis is essential; QUS presents itself as a non-destructive, nonionizing, inexpensive technique for the assessment of the mechanical properties of bone, which would contribute to the detection of osteoporosis, and would also allow the formulation of a fracture threshold.
This was expected since fracture threshold is a measure of the mechanical strength of the coating material, independent of the substrate difference.

Of adult women with anorexia nervosa, 38% have osteoporosis, and 50% have a bone mineral density (BMD) level below the fracture threshold.
When a relatively thick layer of soft tissue was simulated with 1 inch of foam surrounding the surrogate femur, all the hip protectors reduced the force of the impact to below the average fracture threshold.
The decrease in bone quality may not only cause individuals to cross a fracture threshold earlier, but, we hypothesize, it may also impede normal fracture healing.

Energy-shunting external hip protector attenuates the peak femoral impact force below the theoretical fracture threshold.
Unlike adults, the fracture threshold with low bone mineral density in pediatric patients is unknown.
Vertebral fractures are often induced by minor trauma, especially among the oldest age groups, where most women are expected to be under the fracture threshold of bone mineral density [3-5].
