Abstract
|
|
|
Osteoporosis is a skeletoal condition that characterized by reduction in bone volume and clinically expressed as fracture. Osteoporosis is most common metabolic bone disease and is an increasingly common problem and constitutes one of the most
important
major public health problems worldwied.
The correlation between reduced bone mineral density(BMD) and fracture has been clearly demonstrated. Many methods have been developed for quantitative assessment of the MBD. Recently Quantitative Computed Tomography(QCT) has been investigated as
a
means for non-invasive quantitative determination of BMD of the spine.
Spinal bone mineral density was evaluated in 497 women, aged 40 to 65 years old in menopause clinic, Chung-Ang University Hospital from many 1990 to 1993, which was carried out by using QCT. The bone density described by amount of mg/cc K2HPO4,
BMD
showed rapid decrease during twenty five years in women from froty up to 65 years. Actual loss of BMD was 70.30mg/cc K2PHO4 during this period, which account for 49.38% decrease from initial BMD in women of froty years. Average annual bone loss
was
2.06%. At same chronological age, mean bone density was significantly lower in perimenopausal women than chronological age, mean bone density was significantly lower in perimenopausal women than in premenopausal women. The percentile of BMD was
also
presented.
