Frost（1987 a）提出了一种算法，用于估计与观察到的骨单位群体密度（OPD）相对应的缺失骨单位数量。这样的算法应该允许更准确地估计骨重建率的骨骼仍然是在体内标记是不可能的。为了验证该算法，在44根肋骨的尸检样本上进行了测试。使用新算法估计的激活频率（μ RC）和骨重建率（Vf，r，t）与年龄匹配的四环素为基础的值是合理的协议。尽管该算法生成的激活频率（mu RC）和骨形成率（Vf，r，t）的平均值通常较低，但仅在包括5岁以上所有年龄的年龄类别中，它们低于1个标准误。现在是适当的算法应用于考古骨骼遗骸。
Frost (1987a) proposed an algorithm for estimating the number of missing osteons that correspond to observed osteon population densities (OPD). Such an algorithm should allow more accurate estimates of bone remodeling rates for skeletal remains for which in vivo labeling is not possible. In order to validate the algorithm, it was tested on an autopsy sample of 44 ribs. Estimates of activation frequency (mu RC) and bone remodeling rate (Vf,r,t) using the new algorithm are in reasonable agreement with age-matched tetracycline-based values. Although mean values for activation frequencies (mu RC) and bone formation rate (Vf,r,t) generated by the algorithm were generally lower, they fell below 1 standard error for only an age category that included all ages above the 5th decade. It is now appropriate to apply the algorithm to archaeological skeletal remains.
