The age changes that occur in human trabecular bone were examined by calculating the bone density in the soft X-ray films taken from the 3rd lumbar vertebra with an image processing system. The samples were obtained from 177 adult corpses (98 males and 69 females). Loss of the trabecular bone density was found in and after the age group of 30s in both sexes, especially in the age group of 50s in female the decrease in bone density was remarkable. The bone density scattered widely in all age groups, even in the young group. The wide dispersion of bone density in the same age group may produce some unreliable results for estimating the age, so this estimation method should cautiously be applied to actual identification cases.
通过使用图像处理系统计算从第三腰椎获取的软X线片中的骨密度，研究了人类小梁骨发生的年龄变化。样本取自177具成年尸体（98例男性和69例女性）。在30多岁及以后的年龄组中，男女均发现小梁骨密度降低，尤其是50多岁的女性，骨密度下降明显。在所有年龄组中，甚至在年轻组中，骨密度分布广泛。同一年龄组中骨密度的广泛分布可能会在估计年龄时产生一些不可靠的结果，因此这种估计方法在实际鉴定案例中应谨慎应用。
