腰椎骨密度与腰椎间盘突出症的关系

Relationship between Bone Mineral Density in the Lumbar Vertebra and Lumbar Disc Herniation

目的研究腰椎间盘突出症(LDH)患者与正常人腰椎骨密度(BMD)的差异,探讨BMD对LDH的影响。方法抽取LDH患者101例,其中男性56例,女性45例,年龄22～69岁;≥50岁以上45例,<50岁56例。随机抽取101例性别、年龄、身高、体重与LDH组相匹配的健康体检者作为正常对照组,对其骨密度值进行配对比较分析。结果在年龄<50岁的患者,LDH组的BMDT值低于相应的正常对照组,差异有统计学意义(P<0.01);≥50岁组,两者差异无统计学意义(P>0.05)。结论年轻患者LDH与腰椎BMDT值存在一定关系。

Objective To compare the lumbar spine bone mineral density（BMD）between lumbar disc herniation patients and normal people and study the relationship between lumbar disc herniation and BMD.Methods 101 patients with lumbar disc herniation were included,of which 56 were males and 45 were females,age 22-69.The younger than 50-year-old group were 45 cases and older than 50-year-old group were 56 cases.Identical sample of healthy individuals with matched sex,age,height,weight were served as control group.The BMD Tscores were measured and analyzed with paired t-test.Results In the patients younger than 50-year-old,BMD was lower than that of their partner group（P0.01）,but no significance was found in the patients older than 50-year-old（P0.05）.Conclusion In the younger patients,the development of lumbar disc herniation is correlated with their bone mineral density.
