Abstract

PURPOSE

To determine reference values for vertebral heights in healthy young Danish males using morphometric X-ray absorptiometry (MXA).

MATERIAL AND METHODS

A population-based study group of 487 males aged between 20 and 30 years (mean 25 years) from the county of Funen, Denmark, were recruited. Using a Hologic QDR 4500 (dual energy X-ray absorptiometry) DXA-scanner, MXA scans covering the vertebrae from T4 to L4 were acquired for each subject. Anterior (Ha), middle (Hm), and posterior (Hp) heights of the thoracic (T4-T12) and lumbar (L1-L4) vertebral bodies were measured. Moreover, wedge, mid-wedge, crush I, and crush II ratios were calculated.

RESULTS

No correlation between vertebral dimensions and crush indices on the one hand and age or weight on the other were found. Body height, however, correlated significantly with the cumulated vertebral heights. Reference data for vertebral dimensions, wedge, mid-wedge, crush I, and crush II are tabulated.

CONCLUSION

The anterior, middle, and posterior heights of the vertebral bodies of T4 to L4 can be measured reproducible with MXA. In young men, the cumulative vertebral heights correlated with body height but not with age. Moreover, the wedge and crush indices were unrelated of both age and height.

摘要

目的

使用形态计量X线吸收法（MXA）确定健康年轻丹麦男性的椎体高度参考值。

材料与方法

招募了来自丹麦菲英岛的487名年龄在20至30岁（平均25岁）之间的男性作为基于人群的研究组。使用Hologic QDR 4500（双能X线吸收法）DXA扫描仪，为每个受试者获取覆盖T4至L4椎体的MXA扫描图像。测量胸段（T4 - T12）和腰段（L1 - L4）椎体的前（Ha）、中（Hm）和后（Hp）高度。此外，计算楔形、中楔形、I型压缩和II型压缩比率。
