Morphometric research and sex estimation of lumbar vertebrae in a contemporary Spanish population

Virtual Morphometry of the First Lumbar Vertebrae for Estimation of Sex Using Computed Tomography Data in the Turkish Population

“…In previous studies, it has been stated that sex estimation can be made with an accuracy rate exceeding 80% with equations created by discriminant function analysis from metric measurements made on L1 vertebra [ 11 - 12 , 14 - 15 ] (Table 6 ). However, in our study population, an accuracy rate of more than 80% could not be obtained in the equations created using metric measurements on the L1 vertebra.…”

“…It was seen that the accuracy rate of the equation, which was created using the measurements related to the vertebral processes, was 69.7% in the sex estimation. In previous studies, it is seen that the measurements related to the vertebral body are dominant in the equations created for sex estimation from the L1 vertebra [ 11 - 12 , 15 ]. In the study of Decker et al it was stated that the measurements of the vertebral pedicles in the obtained discriminant function equation were more effective in assigning sex [ 14 ].…”

“…Today, many parts of the adult skeleton are used for sex estimation [3]. Studies on the vertebral column have also shown that the vertebrae demonstrate sexual dimorphic features [6][7][8][9][10][11][12][13][14][15].…”

“…Decker et al reported that each of the lumbar vertebrae demonstrated sexual dimorphism exceeding 80% using discriminant function analysis [ 14 ]. Azofra-Monge and Alemán Aguilera in their study evaluating the lumbar vertebrae stated that the lumbar vertebrae showed more sexual dimorphism in their study compared to previous studies, and the highest accuracy rates in the regression equations were obtained from the L1 vertebra (90.1-94.5%) [ 15 ]. Studies show that sex estimation can be made using lumbar vertebrae with high accuracy rates [ 11 - 12 , 14 - 15 ].…”

Studies show that sex estimation can be made using lumbar vertebrae with high accuracy rates [ 11 - 12 , 14 - 15 ]. It has also been shown in studies that, of the five lumbar vertebrae, especially the first lumbar vertebra is more sexually dimorphic than the other lumbar vertebrae [ 12 , 14 ].…”
