Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly . [ 3 ]
DXA is only able to provide the areal bone mineral density. High-resolution peripheral quantitative computed tomography (HR-pQCT) is better than DXA at detecting bone microarchitecture, modeling whole-bone geometry using 3-dimensional information from scans. This method allows estimation of bone strength and other mechanical properties. [20]
DEXA assessment of bone mineral density of the femoral neck (A) and the lumbar spine (B): T scores of - 4.2 and - 4.3 were found at the hip (A) and lumbar spine (B), respectively in a 53-year-old male patient affected with Fabry disease. The World Health Organization has defined the following categories based on bone density in white women:
But I have significant bone loss, I have osteoporosis and osteopenia.” A 30-year-old woman reported having osteoporosis after using Ozempic for a year Image credits: averyofficial
Nearly 20 percent of women under 30 already showing signs of low bone density and conditions like osteopenia and osteoporosis becoming more common as we age (thank you, menopause), as reported by ...
It is often due to osteoporosis; in the vast majority of cases, a hip fracture is a fragility fracture due to a fall or minor trauma in someone with weakened osteoporotic bone. Most hip fractures in people with normal bone are the result of high-energy trauma such as car accidents, falling from heights, or sports injuries.
The first stage is an oedema of the bone marrow initiated by a bone infarct, which is itself modulated by numerous causes, leading to myelofibrosis as a result of hypoxia and gradual loss of bone density characteristic of ischaemic osteoporosis. Further deterioration can be triggered by additional bone infarcts leading to anoxia and localized ...
This double whammy can lead to a vicious cycle of dropping levels, putting us at risk for thin, weakened bones—and, ultimately, osteoporosis and bone fractures, Tang says. Since vitamin D ...
