摘要
50岁以后发生骨折的危险因素有许多方面。其中非暴力因素引起的脊椎、股骨颈及腕部等以小梁骨占优势的部位骨折的发生率则因骨量的逐步减少而连续上升。因此骨密度的监测对骨质疏松症的诊断和提示骨折的危险值是积极预防骨质疏松骨折的一个重要手段。
AbstractBone mineral density(BMD)of 89 cases of frac-tures caused by osteoporosis were examined with double photon bone densitometer(LUNAR DPL),for thewhole body, at the lumbar spine,the femoraI neck. Ward’s triangular area and the trochanter,The per-centage of decrease of BMD was calculated by their ra-tios with the normal value l which was provided by thedata of BMD of the Chinese population in Taiwan. BMD of the vertebrae and the femoral neckdecreasedsharply in the females of age between 60~69 years af-ter menopause. Cases of fracture increased significantlv at these two Iocations.The same problem in malesoftenoccurred after the age of 70.BMD decrease inthe female appeared 10 years earlier than that in themales. For the prevention of fracture in the elderly,BMD examination is of great significance.
