Age Estimation From the Rib by Components Method Analysis in White MalesVerzeletti, Andrea MD; Cassina, Matteo MD; Micheli, Lorenzo MD; Conti, Adelaide MD; De Ferrari, Francesco MDThe American Journal of Forensic Medicine and Pathology: March 2010 - Volume 31 - Issue 1 - p 27-33 doi: 10.1097/PAF.0b013e3181c0e7a5 Original Article Abstract Author Information 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. From the Department of Forensic Medicine, University of Brescia, Brescia, Italy.
