The compression characteristics of 25 fresh cadaveric vertebrae of different height had been analysed in static compression tests and related to CAT densitometry values. A relationship between fracture load and CAT densitometry values of the vertebral body (spongiosa and corticalis) had been found, which can be described as a logarithmical function (r2 = 0.91). Separated CAT measurements of spongiosa also showed a logarithmical function (r2 = 0.89). Consequently, the thin corticalis of vertebral waist is of subordinate importance in correlation to fracture load. An analogously explored average CAT densitometry value showed no definite dependence on corticalis capacity. The graphic description of analysed spongiosa areas in absorption profile (CAT histogram) almost resulted in a Gauss distribution.
对25个不同高度的新鲜尸体椎体进行了静态压缩试验,分析其压缩特性,并与计算机断层扫描(CAT)骨密度测量值相关联。已发现椎体(松质骨和皮质骨)的骨折负荷与CAT骨密度测量值之间存在关系,这种关系可用对数函数描述(r2 = 0.91)。松质骨的单独CAT测量结果也显示为对数函数(r2 = 0.89)。因此,椎体腰部较薄的皮质骨与骨折负荷的相关性较小。类似地探究得到的平均CAT骨密度测量值并未显示出对皮质骨容量的明确依赖性。在吸收曲线(CAT直方图)中对分析的松质骨区域进行图形描述,结果几乎呈高斯分布。
