摘要
目的 用定量超声骨质测量仪对中老年妇女骨折病人检测 ,探讨其参数的意义 ,为骨质疏松性骨折的诊断、防治提供科学依据。方法 用法国DMS公司UBIS 50 0 0型超声骨密度 /骨质量测量仪测量 74例 41岁以上中老年妇女骨折病人的骨质 ,并与 2 1 8例同龄健康妇女作对照。结果 61岁以前 2组宽波段超声衰减平均值 (BUA)比较差异无显著意义 (P >0 0 5)、而 61岁以后则有显著意义 (P <0 0 1 ) ;51岁以前 2组超声传播速度 (SOS)值比较差异无显著意义 (P >0 0 5)、而 51岁以后则有显著意义 (P <0 0 1 ) ;在绝经后早期 (51～ 60岁 ) 2组比较 ,BUA值差异无显著意义 (P >0 0 5)而SOS值则已有显著意义 (P <0 0 1 )。结论 定量超声骨质测量仪不仅可以提供骨量的指标 ,而且可以对骨结构进行评估 ,无辐射、成本低廉、操作方便 ,在骨质疏松性骨折的早期预测。
Objective To study the significance of parameters by quantitative altrasound (QUS) in middle aged and aged women with fracture, providing scientific basis for prevention and treatment of osteoporosis (OP) Methods Bone status was established by measurements of calcaneus using QUS(DMS, French) for speed of sound (SOS, m/s), broadband ultrasound attenuation (BUA, dB/MHz)and stiffness index (SI,%) in 74 women with fracture The results were compared with those of 218 healthy women in the same age Results Compared between the two groups, BUA showed a significant difference( P <0 01) after 61y of age, while SOS did so after 51y of age (P <0 01) In the earlier period of postmenopause(51 60y), SOS showed a significant difference( P <0 01) Conclusion QUS of bone is a promising technique for assessing bone microarchitecture in addition to bone mass, which is cheaper and easier to use than the established method of bone densitometry
