Abstract

In the last years, anthropology has been widely explored mainly when related to bones due to its morphologic characteristics, such as the rhomboid fossa of the clavicle. This study examined the incidence of the rhomboid fossa in paired clavicles of Brazilian subjects obtained from 209 adult bodies of known age and sex (107 males and 102 females) on which postmortem examinations had been performed by the senior author. The data were submitted to qualitative statistical analysis according to Fisher. There was a statistical difference (p= 5.98 x 10-23) between sexes related to the frequency of the rhomboid fossa. The fossa was absent in 97,1% of the female clavicles and the incidence of bilateral fossa was present in 2,9% of females. The incidence of bilateral fossa was 29% for male clavicles. The sexual or side differences in the incidence of the fossa could be found in this study, and qualitative analysis can corroborate sex determination of unidentified bodies in forensic medicine.
