【摘要】：目的探讨中老年男性在应用双能X线骨密度仪检测不同部位骨密度时应关注检测的部位。方法选取2012年9月至2014年12月在我院行双能骨密度检测的中老年男性,比较腰椎、髋部、前臂桡骨下1/3的骨密度(BMD)和T值。结果中老年男性腰椎、髋部、前臂桡骨下1/3三个部位的BMD和T值比较,P0.001差异有统计学意义。随着年龄逐渐增大,腰椎BMD和T值下降不明显,髋部、前臂BMD和T值60岁以后才逐渐降低,前臂T值下降幅度明显大于腰椎和髋部。随着年龄的增加,髋部及前臂骨质疏松检出率也逐渐增加,但腰椎骨质疏松检出率随年增加反而下降。结论应用双能X线骨密度仪检测腰椎、髋部、前臂3个部位,经比较发现老年男性髋部和前臂BMD和T值明显低于腰椎,而且腰椎BMD和T值相对平稳,提示对老年男性骨质疏松诊断应同时检测髋部和前臂骨密度,以免出现骨质疏松的漏诊。
[Abstract]:Objective to investigate the sites of dual energy X ray absorptiometry in the detection of bone mineral density (BMD) in middle aged and aged men. Methods from September 2012 to December 2014, the bone mineral density (BMD) and T value of lumbar vertebrae, hip and forearm were compared among middle-aged and aged men who had been tested for dual energy bone mineral density (BMD) in our hospital from September 2012 to December 2014. Results the BMD and T values of lumbar vertebrae, hip and forearm in the middle and old men were significantly higher than those in the middle and old men (P 0. 001, P 0. 001). With the age increasing, the BMD and T values of the lumbar vertebrae did not decrease significantly, but the BMD and T values of the hip and forearm decreased gradually after 60 years old. The decrease of T value of the forearm was obviously greater than that of the lumbar vertebrae and the hip. With the increase of age, the detection rate of osteoporosis in hip and forearm increased gradually, but the detection rate of osteoporosis in lumbar vertebrae decreased with the increase of age. Conclusion the BMD and T values of the hip and forearm of the elderly men were significantly lower than that of the lumbar vertebrae, and the BMD and T values of the lumbar vertebrae were relatively stable by using dual energy X-ray absorptiometry. The results suggest that bone mineral density of hip and forearm should be detected simultaneously to avoid missed diagnosis of osteoporosis.
