【摘要】 目的评价放射吸收法测定指骨骨密度(BMD)的变化规律及在京郊边远山区进行普查应用的可行性。方法从受检的1146例患者中,选取20～79岁无其他任何因素影响的健康人群554例。男性271例,女性283例,按每10岁一个年龄组进行BMD测定。结果男性非优势手指中节指骨(MP2～4)骨密度峰值在20～39岁组,40岁以后随年龄增长逐渐下降,至79岁无明显加速变化现象。女性非优势手指中节指骨(MP2～4)骨密度峰值在20～39岁组,50岁以后明显下降。结论采用放射吸收法测定指骨骨密度(BMD)所获得的测量结果,符合骨质疏松流行病学发病基本规律。且辐射剂量低,误差小,价格低,医院可利用现有X线设备,无须大的投入,即能帮助临床医师准确诊断骨质疏松、确定治疗方案,避免患者的骨密度进一步丢失,减少骨折发生几率,这是适合边远山区应用的一种骨密度测量方法。更多还原

【Abstract】 ObjectiveTo evaluate bone mineral density (BMD) pattern changes in phalangeal bones using Radiographic Absorptiometry (RA) method.Methods554 healthy participants, including 283 women and 271 men aged 20-70 years, were selected. The participants were grouped according to every 10 years age intervals.ResultsIn male group, the peak value of phalangeal BMD (MP2-4) of the non-dominant hand occurred between the age of 20-39 years, then decreased the age of 40 years and there is still no dramatic to decline 79 years old. In female groups, the peak value of phalangeal BMD(MP2-4) of the non-dominant hand occurred between the age of 20-39 years, but sharply after 50 years old descended.ConclusionBMD at phalangeal bone measured by RA method is inaccording with osteoprosis epidemiological regular pattern.更多还原
