长寿老人胸腰段椎体测量

Measurement of Thoracolumbar Spine in Long-Lived Subjects

目的 为长寿老人骨质疏松症的研究提供有价值的资料。方法 对 5 6例 90～ 10 2岁长寿老人第 12胸椎和第 1腰椎椎体前后缘及中部的高度 ,椎体中部前后径和T12 、L1椎间盘的厚度进行测量 ,并就椎体变形情况进行观测分析。结果 上述观测指标男性大于女性 (P <0 .0 5 ,P <0 .0 1) ;椎体变形以楔状变形与鱼椎样变形共存 (混合型 )为主 ,共计 69个 (占61.6% )。结论 长寿老人骨质疏松症所致胸腰椎变形的发生率明显高于国内文献报道的老年人数据 ,其严重骨质疏松是在骨生理性老化的基础上多种因素共同作用的结果。

Objective To provide the valuable data for studying osteoporosis of long lived subjects. Methods The anterior,posterior and central heights and central anterioposterior diameters of T 12 and L 1 vertebral bodies and thickness of T 12 L 1 intervertebral disks were measured in 56 long lived subjects,aged 90-102 years and deformities of T 12 and L 1 vertebral bodies were surveyed and analysed. Rusults The above mentioned values were larger in male than those in female ( P < 0.05 , P <0.01). The deformities of vertebral bodies were mainly the combination of wedging and biconcave ones (mixed type). The deformed vertebral bodies in this type came to 69 (61.6%). Conclusion The incidence of deformities of thoracolumbar spine due to osteoporosis in long lived subjects is much higher than that in the aged described by domestic reports. They results from action in concert of various factors on the basis of physiologic aging.
