目的:通过分析腰椎和髋部骨密度,评价两者在骨质疏松诊断上的差别和意义。方法:2000-01/2004-03在中国长城铝业公司总医院经双能X射线骨密度仪检查确诊为骨质疏松的190例患者,按年龄进行分组,分析不同年龄、不同部位骨量减少和骨质疏松的发生率。结果:腰椎和髋部的骨质疏松发生率与年龄存在正相关关系(χ2=20.7328,32.1887,P<0.05,Pearson列联系数0.3137,0.2336,Cramer列联小数0.2336,0.2910),符合人体骨质疏松发生发展变化规律。腰椎和髋部的骨质疏松和骨量减少发生率在各年龄组之间差异均无显著性意义(χ2=7.2082,3.1846,P>0.05)。结论:腰椎和髋部的双能X射线骨密度仪测量部位选择应综合分析与判断,以期达到早期发现与治疗骨质疏松,预防骨折的发生。
OBJECTIVE: To evaluate the difference and significance of the two in the diagnosis of osteoporosis by analyzing the bone mineral density of lumbar spine and hip. METHODS: A total of 190 patients with osteoporosis who were diagnosed as osteoporosis by dual energy X-ray absorptiometry at the General Hospital of Great Wall Aluminum Corporation of China from January 2000 to March 2004 were divided into groups according to their age. The bone mineral density And the incidence of osteoporosis. Results: The incidence of osteoporosis in lumbar spine and hip had a positive correlation with age (χ2 = 20.7328,32.1887, P <0.05, Pearson’s correlation coefficient 0.3137,0.2336, Cramer’s correlation coefficient 0.2336,0.2910) Loose occurrence of the law of development and change. The incidence of osteoporosis and osteopenia in lumbar spine and hip were not significantly different among all age groups (χ2 = 7.2082,3.1846, P> 0.05). Conclusion: The measurement of lumbar spine and hip by dual energy X-ray absorptiometry should be based on comprehensive analysis and judgment in order to achieve the early detection and treatment of osteoporosis and prevent the occurrence of fractures.
