Abstract
Osteoporosis is a major public health problem throughout the world. Elderly people are the fastest growing populations in the world and, as people age, bone mass declines and the risk of fractures increases.
According to the world health organization, osteoporosis is considered the 10th most important disease associated with the progress of civilization in the contemporary world.
Osteoporotic fractures constitute a serious problem, both for the public health and health care system. The consequences of osteoporotic fractures encompass an increased percentage of disabled people in an aging society. It is a major public health problem worldwide because of the associated morbidity, mortality and costs.
The gold standard for the diagnosis of osteoporosis is DEXA, The early identification of individuals with low BMD and/or clinical risk factors, accurate diagnosis of osteoporosis and osteopenia, and initiation of appropriate treatment are crucial to reducing the incidence of fractures.
In this study, we examined the relationship between CID/AS ratio and spinal height and results of DEXA. As, we hypothesized that those two simple measurements might prove to be a useful tool for the identification of patients with early spinal vertebral height loss or occult vertebral fracture, osteoporosis in an post-menopausal female population.
We examined data from 100 elderly women (50 cases and 50 controls) with (mean age + SD =59.65+5.25) attending Eldemerdash hospital for DEXA bone densitometry.
Each participant had measurement of BMD using DEXA scan and CID/AS ratio using a caliper device, corrected for standing height by dividing the CID by the subject’s AS. This was referred to as the CID/AS ratio.
Results of the current study showed that there was a significant correlation between CID/AS ratio and bone mineral density as regard T score at femur neck and T score at femur trochanter.
The best cut off value of CID/AS ratio ≤ 0.057 to diagnose osteoporosis with Sensitivity = 74% , Specificity = 56% and positive predictive value 62.7% .
