Primary, or involuntary osteoporosis, can further be classified into Type I or Type II. [1] Type I refers to postmenopausal osteoporosis and is caused by the deficiency of estrogen. [1] While senile osteoporosis is categorized as an involuntary, Type II, and primary osteoporosis, which affects both men and women over the age of 70 years.
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.
Dual-energy X-ray absorptiometry (DEXA scan) is considered the gold standard for the diagnosis of osteoporosis. Osteoporosis is diagnosed when the bone mineral density is less than or equal to 2.5 standard deviations below that of a young (30–40-year-old [4]:58), healthy adult women reference population.
Osteomalacia is a disease characterized by the softening of the bones caused by impaired bone metabolism primarily due to inadequate levels of available phosphate, calcium, and vitamin D, or because of resorption of calcium.
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.
The ISCD states that there is no clearly understood correlation between BMD and the risk of a child's sustaining a fracture; the diagnosis of osteoporosis in children cannot be made on the basis of densitometry criteria. T-scores are prohibited with children and should not even appear on DXA reports.
Single photon absorptiometry is the first quantitative analysis method used in the diagnosis of osteoporosis. To evaluate bone quality, bone mineral content (BMC) and bone mineral density (BMD) are important indicators, and bone quality can reflect the health status of normal human bone tissue to a certain extent.
Osteoporosis, a skeletal disorder characterized by compromised bone strength and increased risk of fractures, is a major concern in bone health, particularly among older adults. [ 2 ] [ 3 ] Maintaining good bone health involves a combination of adequate calcium and vitamin D intake, regular weight-bearing exercise, and avoiding risk factors ...
