title: [The determination of age and sex from measure of the humerus (author's transl)].
abstract: On a total of seventy left humeri of persons in their third to ninth decades of life thirty different bone dimensions were determined macroscoically and checked for age dependence. Strong dependence on age was shown only by the weight and volume of the humerus as well as by the areal and thickness dimensins of the center of the shaft. These were used to set up multidimensional linear regression functions by which it is possible for the age of persons past thirty to be estimated with defined accuracy. Also calculated were discriminant functions which allow the sex of a person to be identified to be determined from three dimensions of the left humeral head, and these are the size of the caput at the cartilage-to-bone interface, the transverse and vertical diameters of the caput humeri or head of the humerus. Of the 49 cases studied only three were found to be in the region of overlap of the dimensions used for calculation. Consequently, the formula would not allow unknown humeri or skeletons, respectively, to be identified as belonging to either male or female persons in 6 percent of the cases only. The results of additional examinations made of 198 right humeri were less accurate and showed a decrease of the sexual dimorphism of bone with age.
