Estimation of Age at Death by Femoral Osteon Remodeling: Application of THOMPSON'S Core Technique to Modern Japanese

THOMPSON'S core technique for estimation of age at death was applied to 52 modern Japanese cadavers. Bone cores with 4mm in diameter were removed from anterior midshaft of left femur of 28 males and 24 females ranged in age from 43 to 98 years. Variables used in this study include cortical thickness, core weight, total secondary osteon number, mean secondary osteon area, secondary osteon area standard deviation, mean secondary osteon perimeter, secondary osteon perimeter standard deviation, and total secondary osteon area. Multiple regression formula was calculated in both sexes. Multiple correlation coefficients and standard errors were 0.581 and 9.28 in males, 0.748 and 9.95 in females, respectively.
