title: Age estimation from the rib by components method analysis in white males.
abstract: Changes at the sternal extremity of the fourth rib have already been established as reliable indicators of age at death. Still now, the Iscan "phase method," based on the morphologic changes at the sternal extremity of the fourth rib, is one of the best effective for age estimation at death. The present study was carried out to develop an alternative method considering the morphologic characteristics of articular surface (A), anterior/posterior walls (B), and superior/inferior edges (C) of the sternal extremity of the fourth rib. For each parameter a numerical score was assigned and some regression formulae was elaborated. The best correlation between morphologic characteristics and age was obtained through the formula Age = 10.43 (AB)(0.53). The sample consisted of sternal extremities of the fourth rib obtained at autopsy from 49 white males of known age.
