SIGNIFICANCE OF SACRAL INDEX IN ESTIMATION OF SEX OF SACRUM IN CENTRAL RAJASTHAN
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 64
Abstract
BACKGROUND Anatomists, anthropologists and forensic experts judge the sex of the skeletal material by non-metric observations. Sex-dependent differences have been noted in the pelvic bone anatomy, and so differences exist in male and female sacrum. Over the years, different authors had carried various types of measurements on human sacra of different races. The well-known method for determination of sex of sacrum has always ideally been the Sacral Index method as explained in the Hrdlicka’s Practical Anthropometry. The formula for Sacral Index is: Sacral Index = Width of Sacrum x 100/ Length of Sacrum. The aim of this study was to collect data regarding morphometric measurements of maximum length and breadth of sacrum and to find out possible variations of sacral index in different individuals in relation to sex. MATERIALS AND METHODS A descriptive study was conducted in the Department of Anatomy, Govt. Medical College, Kota on 75 (seventy-five) adult human dry sacra of unknown sex. The sacral bones were distributed into male (40) and female (35) groups by discriminant functional analysis. The study sample was studied morphologically for sacral length and sacral breadth with digital sliding Vernier caliper. RESULTS The mean sacral index in male and female were 97.88 ± 6.16% and 112.69 ± 10.17% respectively. Female has the greater sacral index than male (P < 0.001). CONCLUSION The bones of the body are the last to pass away after death, next to enamel of teeth. Medico-legal experts, anatomists and anthropologists use the skeletal materials for giving their opinion in respect to sex, age and stature for establishing the personal identity. Sacral index method is relevant and significant for determination of sex.
