The purpose of this study is to compare and analyze the bone mineral content of women who went through osteoporotic menopause and that of women who are healthy. For the purpose, this researcher sampled some women and divided them into three groups. Group 1 consisted of women who were pre-menopausal and healthy, group 2, women who were post-menopausal and health and group 3, women who went through osteoporotic menopause. The researcher measured the bone density of all the subjects and compared its difference among the three groups. Then the researcher compared and analyzed the influences of bone density on the spine among women of each group or those of all the groups. Among all regions of the spine, that of most region was spongiosa which was ovally shaped. The researcher measured the bone mineral content of spongiosa which existed in a particular section of the spine between T12 and L4. Findings of the study can be summarized as follows. The older women were, the lower their bone density was. Especially, women who had osteoporosis were significantly lower in bone density than those who were healthy. In all women, except those of group 1, bone density more and more lowered as the measured region of the spine gradually moved from T12 to L4. From a statistical view, the bone density of the entire vertebral body could discriminate the groups 1, 2 and 3. But it was not possible to discriminate between the groups 2 and 3 only with the bone density of the most interested region as mentioned above.
