FRAX (fracture risk assessment tool) is a diagnostic tool used to evaluate the 10-year probability of bone fracture risk. It was developed by the University of Sheffield . [ 1 ]
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 US National Osteoporosis Foundation recommends pharmacologic treatment for patients with hip or spine fracture thought to be related to osteoporosis, those with BMD 2.5 SD or more below the young normal mean (T-score -2.5 or below), and those with BMD between 1 and 2.5 SD below normal mean whose 10-year risk, using FRAX, for hip fracture is ...
At the spine, a volumetric BMD measurement is made using QCT and rather than using T-Scores, it should be compared to guideline thresholds from the American College of Radiology (ACR): [16] a BMD < 80 mg/cm3 indicates osteoporosis; a BMD < 120 mg/cm3 and > 80 mg/cm3 indicates osteopenia; and a BMD above 120 mg/cm3 is considered normal.
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.
Information from the DXA scanner creates a bone mineral density T-score by comparing a patient's density to the bone density of a healthy young person. Bone density between 1 and 2.5 standard deviations below the reference, or a T-score between −1.0 and −2.5, indicates osteopenia (a T-score smaller than or equal to −2.5 indicates ...
Open fracture, wound > 1 cm but < 10 cm in length [4] without extensive soft-tissue damage, flaps, avulsions IIIA Open fracture with adequate soft tissue coverage of a fractured bone despite extensive soft tissue laceration or flaps, or high-energy trauma ( gunshot and farm injuries) regardless of the size of the wound [ 5 ] [ 6 ]
Bone density. The basic principle of single-photon bone mineral density measuring instrument is to calculate the attenuation degree of single-energy gamma photon beam through bone tissue. The more attenuation degree is, the more absorbed by bone minerals, the more bone mineral content and the higher bone mineral density are.
