目的研究国际新近发展的胫骨超声速率（ＳＯＳ）与双能Ｘ线吸收法（ＤＥＸＡ）及单光子吸收法（ＳＰＡ）测定的骨密度（ＢＭＤ）的相关性。方法对２１３名年龄２２－８３岁（平均５４．３±１５．２岁）的女性健康志愿者及５６例年龄５３－８３岁（平均６７．９±７．４岁）的原发性骨质疏松症椎体骨折患者进行胫骨ＳＯＳ及ＤＥＸＡ、ＳＰＡ骨密度测定。结果２１３名健康志愿者的胫骨ＳＯＳ值与ＤＥＸＡ测定的４个部位ＢＭＤ值和ＳＰＡ测定的２个部位的ＢＭＤ值呈显著的正相关〔Ｐ＜０．００１）；选取１０４名年龄、绝经年限及体重指数与骨折组，相匹配的健康志愿者（平均年龄６６．９±６．１岁）作为对照组，与椎体骨折组进行比较两组之间的胫骨ＳＯＳ值有显著差别（Ｐ＜０．０１）。结论胫骨ＳＯＳ与ＤＥＸＡ及ＳＰＡ测定的６个部位的ＢＭＤ值有非常显著的正相关；胫骨ＳＯＳ在椎体骨祈组与对照组之间有显著差别。
Objective To study the relationship between newly developed tibiae sonic rate (SOS) and bone mineral density (BMD) measured by dual energy X-ray absorptiometry (DEXA) and single photon absorption (SPA). Methods Totally 213 female volunteers aged 22-83 years (mean 54.3 ± 15.2 years) and 56 primary osteomas aged 53-83 years (average 67.9 ± 7.4 years) Osteoporosis in patients with osteoporosis vertebral tibia SOS and DEXA, SPA bone mineral density determination. Results The tibial SOS values of 213 healthy volunteers were positively correlated with the BMD of 4 sites measured by DEXA and the BMD of 2 sites measured by SPA [P <0.001]. 104 age, menopausal years, Body mass index and fracture group, the matched healthy volunteers (mean age 66.9 ± 6.1 years) as the control group, compared with the vertebral fracture group, the tibia SOS value was significantly different between the two groups (P <0 .01). Conclusions There is a significant positive correlation between the SOS of the tibia and the BMD of the six sites measured by DEXA and SPA. There is a significant difference between the SOS of the tibia and the control group.
