摘要
目的通过对骨折患者各部位的骨密度分析,评价不同部位骨密度对骨折的预测作用。方法191例患脆性骨折的女性患者来自2000~2004年青岛市区五家医院的骨科。采用双能X线骨密度测量仪同时测量191例患者的仰卧正位腰椎2至4椎体BMD(g/cm2),左侧髋部股骨颈、大转子、和Ward’s三角区BMD(g/cm2)处骨密度,与当地同性别峰值骨量进行比较。结果各部位骨质疏松诊断率L2是最高的,经卡方检验,L2预测价值大于L3、L4、及WARD三角区,但与NECK及GT无统计学差异。结论在常用的骨密度测定部位中,L2对骨质疏松骨折的预测作用最大。
Objective In this study, bone mineral density analyses in various parts of patients with fractures were taken to evaluate the role of fracture prediction through bone mineral density in different parts. Methods 191 cases of female patients with the low-energey fracture were from orthopedics departments in five hospitals in Qingdao districts from 2000 to 2004. The bone mineral density values of orthotopic supine lumbar 2-4 vertebrae BMD (g/cm^2), left hip femoral neck, greater trochanter, and Ward's triangle BMD (g/cm^2) of 191 patients were determined simultaneously with dual-energy X-ray absorptiometer, then the data was compareded with the PBMD of the local wemen. Results The L2's diagnosis rate of osteoporosis was the highest. By ehi-square test, the prediction value of L2 was greater than the value of L3, L4, and WARD triangle, but there was no significant difference between GT and NECK. Conclusions The BMD in L2 played the largest role for osteoporotic fracture prediction in those commonly used parts for bone mineral density determination.
