The trabecular bone score is a measure of bone texture correlated with bone microarchitecture and a marker for the risk of osteoporosis. Introduced in 2008, [ 1 ] its main projected use is alongside measures of bone density in better predicting fracture risk in people with metabolic bone problems.
The weaker spicules of trabecular bone break ("microcracks"), and are replaced by weaker bone. ... T-score range % young women Normal: T-score ≥ −1.0: 85% ...
The range of Young's modulus for trabecular bone is 800 to 14,000 MPa and the strength of failure is 1 to 100 MPa. As mentioned above, the mechanical properties of trabecular bone are very sensitive to apparent density. The relationship between modulus of trabecular bone and its apparent density was demonstrated by Carter and Hayes in 1976. [8]
Bone densities are often given to patients as a T score or a Z score. A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower.
It is the bone mineral density at the site when compared to the "young normal reference mean". It is a comparison of a patient's bone mineral density to that of a healthy 30-year-old. [ 10 ] The US standard is to use data for a 30-year-old of the same sex and ethnicity, but the WHO recommends using data for a 30-year-old white female for ...
The Getty Center, perched on a hill above the much-traveled 405 freeway, is a 30-minute drive away (in normal conditions) and out of the immediate fire zone, was also closed through Monday.
This amount can range from $250 to $1,000 or more, depending on your policy choices. Average cost: Around $743 annually. 3. Comprehensive coverage. ... Maintain a good credit score.
At the hip, a DXA-equivalent T-score may be calculated for comparison to the WHO classification at the proximal femur as normal, osteopenia (T-Score < -1.0 and > -2.5) or osteoporosis (T-Score < -2.5). [17] This T-Score may also be used for fracture risk probability calculation in the WHO FRAX tool [18] with "T-Score" as the appropriate DXA ...
