  • Title: Technical note: calculation of age at formation of radiopaque transverse lines.
    Author: Byers S.
    Journal: Am J Phys Anthropol; 1991 Jul; 85(3):339-43. PubMed ID: 1897606.
    Abstract:
    A simple method for determining the age of an individual at the time of radiopaque transverse (Harris) line formation is presented. To use this method, only two measurements are required: total bone length and distance of line to nearest bone end; these are put into formulae that calculate the percent of total bone growth when the line appeared. The result of this calculation is compared with tables of percent bone growth per year (one to 16 years in females and one to 18 years in males) to arrive at estimations of age at line formation. Since these tables are presented for the femur, tibia, humerus, and radius, this technique can be used on any one of the major long bones exhibiting lines.
