摘　　要：目的:探讨原发性骨质疏松症患者腰椎前凸角、骶骨倾斜角的变化特征。方法:85例腰背痛患者入选本项研究,选择39例原发性骨质疏松症患者为观察组,其中男性27例,女性12例,年龄最大77岁,最小50岁,平均年龄(62.35±6.57)岁。同期经检查骨量正常者46例为对照组,男性27例,女性19例,年龄最大72岁,最小53岁,平均年龄(61.56±6.24)岁,研究对象均接受腰椎X线摄片和双能X线骨密度(BMD)检查,测量其腰椎X线片的腰椎前凸角、腰骶椎间盘角、骶骨倾斜角,并进行统计学分析。结果:观察组腰椎前凸角(35.00±19.91)、腰骶椎间盘角(13.87±4.26)、骶骨倾斜角(27.56±7.13),分别与对照组腰椎前凸角(37.61±5.32)、腰骶椎间盘角(17.46±3.29)、骶骨倾斜角(30.07±5.28)相比均偏小,差异均有显著性意义(P<0.05);观察组与对照组腰椎BMD与腰椎前凸角、腰骶椎间盘角、骶骨倾斜角均呈正相关(P<0.05)。结论:腰椎BMD与腰椎前凸角、骶骨倾斜角存在相关性,原发性骨质疏松患者的腰椎前凸角、骶骨倾斜角呈减小趋势,提示原发性骨质疏松有较高的发生腰椎骨折及腰背痛的危险性。Objective： To research the characteristics of lumbar lordosis angle and sacral inclination angle of patients with primary osteoporosis. Method： Eighty-five patients with low back pain were selected. The observation group included 39 patients with primary osteoporosis, of which 27 male and 12 female, 50-77 years old （62.35 _± 6.57）. The control group included 46 patients with normal bone content, of which 27 male and 19 female, 53-72 years old （61.56 ± 6.24）. All the patients of the two groups accepted X-ray bone mineral density（BMD） and Dual energy X-ray tests. The lumbar lordosis angle, lumbosacral disc angle and sacral inclination angle were analyzed. Result： The lumbar lordosis angle （35.00 ± 19.91 vs 37.61 ± 5.32）, lumbosacral disc angle （13.87 ± 4.26 vs 17.46 ± 3.29） and sacral inclination angle （27.56 ± 7.13 vs 30.07 ± 5.28） decreased significantly in observation group than those in control group （P〈 0.05）. There were positive correlations between lumbar BMD and lumbar lordosis angle, lumbosacral disc angle as well as sacral inclination angle respectively both in observation group and control group（P〈0.05）. Conclusion： There is correlations between lumbar BMD and lumbar lordosis angle, lumbar BMD and sacral inclination angle. The lumbar lordosis angle and sacral inclination angle show a decrease trend in patients with primary osteoporosis. It sugges! primary osteoporosis patients maybe have a high possibility to suffer from vertebral fractures and low back pain.
