摘要
目的探讨骨密度与脊柱畸形之间的相关关系。方法应用双能X线仪及Spinalmouse测量腰椎骨密度、股骨颈的骨密度及脊柱椎间夹角,对骨密度与脊柱畸形相关的数据进行相关分析。结果股骨颈骨密度与脊柱各节段之间的夹角均不存在明确的相关关系,而腰椎的骨密度则与胸(T)7/8间隙负相关,而与腰(L)1/2、L5骶(S)1正相关。腰椎骨密度与胸椎立位整体曲度存在明显负相关,股骨颈骨密度则不存在这种相关关系。男性骨密度明显高于女性骨密度。随年龄增长,股骨颈的骨密度与年龄之间存在负相关关系,而腰椎骨密度则未发现明显的负相关。结论 T7/8及L1/2椎间夹角能够反映腰椎骨密度高低。60岁之后,性别对骨密度的敏感度较年龄要高,年龄对股骨颈骨密度的敏感度比腰椎骨密度高。
Objective To study the relationship .between BMD and spinal deformity in old people. Methods Spinal deformity status was measured by Spinal mouse. The BMD of femoral neck and lumbar vertebral body were measured by Dual X-ray machine. Correlation a- nalysis between BMD and spinal deformity were adopted. Results There was no significant relation between femoral neck BMD and any included angles of spine sequence. Thoracic vertebra 7/8 had a negative relation with lumbar vertebra 1/2 and lumbar vertebra 5/sacral vertebra 1. Lumbar vertebrae physiological crooked degrees had significant negative relation with lumbar BMD. The BMD level of man was obvious- ly higher than that of the female. The BMD of femoral neck appeared negative relation with age, but not the BMD of the lumbar vertebra. Conclusions The included angles of thoracic vertebra 7/8 and lumbar vertebra 1/2 have the ability to reflect the lumbar vertebra BMD level. The gender is more sensitive than age to predict the BMD after 60 years old. Age is more sensitive to predict the femoral neck BMD than lumbar vertebra BMD.
