摘要
目的:通过测定多部位骨密度,全面地观察骨矿物质变化,及时发现骨量丢失出现的部位。提高骨质疏松症(OP)的早期诊断和防治。方法:用双能骨密度仪测定113例月经规律的20-56岁妇女腰椎和双髋部的骨密度。结果:88例20-40岁月经规律妇女中腰椎和双髋部BMD在正常范围者76例,出现骨量减少者12例;而49-56岁仍有月经规律的25例妇女中骨量减少者8例。两个年龄组的骨量减少发生率共为17.7%。发生的部位在腰椎或单、双髋或腰髋两者兼之,个体差异较大。多部位腰椎+双髋部骨密度测定能及早了解未绝经妇女的骨矿物质变化。结论:1. 多部位腰椎+双髋部骨密度测定,发现月经规律的部分妇女骨量亦有减少。2. 随着年龄的增加骨量丢失的发生率也增加,应及早采取对妇女行多部位测定BMD,深入了解骨量的变化,提高OP的诊断率。
Aim: to protect from late Osteoporosis (OP ) we measured bone density of pre-menopausal women at various sites to find out changes in bone mineral density. Method: Bone density data was acquired by DEXA (DPX-L) to scan the lumbar spines and hip of 113 women volunteers, aged 20-56 years and analysed. Results: BMD of the lumbar spines and both hips were normal in 76 members of the 88 aged 20-40years menstruating normally. While 12 members and 8 of 25 women aged 49-56 years had decreased bone mineral, an incidence of 17.7%. Sites of decreased mineral density were at the lumbar spines or hips or both lumbar spines and hips, with individual variations. Measuring the bone density of the lumbar spines together with both hips leads to better understanding of the bone mineral condition and loses missing for OP in diagnosis. Conclusions: 1). Measuring BMD of both lumbar spines and hips will protect further bone mineral loss in menstruating women. 2). With advancing age bone mineral loss increased, multisites bone density measurement helps in diagnosing OP accurately.
