Abstract

373 lumbar vertebrae of modern humans (Russians from the city of Dushanbe) have been studied. It was detected that the corpuses of lumbar vertebrae are the most informative for sexing, with L-1 being the most informative one. It was shown that for sex identification the most effective dimensions of the vertebrae corpus are: X4 - the middle height; X6 - the lowest sagittal diameter and X8 - the upper width. The discriminant functions based on these dimensions for the first lumbar vertebrae give about 91% of correct diagnosis. The author suggests a coefficient of discriminant reliability which is proportional to the percentage of correct diagnosis.
