Morphological changes of the pubic symphysis provide an important means of estimating age at death in the adult skeleton. Today, the most widely used method of symphysial aging is the three-component system devised by McKern and Stewart for males and modified by Gilbert and McKern for females. Examination of the published data for both sexes reveals that the relationship of total symphysial score with predicted age and observed standard deviations can be expressed by a set of simple linear and polynomial equations. This approach is more statistically efficient since it uses the total data base rather then independently treated data subsets in predicting age from total symphysial score. It has the added advantage of providing a simple method of predicting symphysial age on small computers or programmable calculators.
耻骨联合的形态变化为估算成年骨骼的死亡年龄提供了重要方法。如今，耻骨联合老化最广泛使用的方法是由麦肯和斯图尔特为男性设计、吉尔伯特和麦肯为女性修改的三分系统。对两性已发表数据的研究表明，耻骨联合总分与预测年龄及观察到的标准差之间的关系可用一组简单的线性和多项式方程表示。这种方法在统计上更有效，因为它在根据耻骨联合总分预测年龄时使用的是整个数据库，而非独立处理的数据子集。它还有一个额外优势，即能在小型计算机或可编程计算器上提供一种简单的预测耻骨联合年龄的方法。
