fracture threshold

fracture threshold

Bone physiology A theoretical cancellous bone density below which osteoporosis-related fractures occur. See Osteoporosis Imaging A benchmark–below which fractures are more common–determined by bone densitometry.

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.8

There is a need to study the BMD-fracture relationship in Indians (fracture threshold) to determine the ideal normative data for the Indian population (34).
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.

When a relatively thick layer of soft tissue was simulated with 1 inch of foam surrounding the femur, all the hip protectors reduced the force of the impact below the average fracture threshold. The hard hip protectors reduced the impact to a significantly greater degree, however.

Unlike adults, the fracture threshold with low bone mineral density in pediatric patients is unknown.
