MORPHOMETRIC ANALYSIS OF ILIAC CREST OF PELVIC BONE FOR SEX DETERMINATION

Abstract

Identification of the sex of the skeletal remains is a important step in biological profiling of the skeletal remains or a badly burnt body in establishing the identity of the individual in forennsic medicine. The parameters of hip bone can be utilised for sex determination in South Indian population. To analyse the dry human pelvic bone with reference to iliac crest to determine the sexual dimorphism. In the present study a total of 40 dry human pelvic bones of unknown sex and without any gross abnormality were collected from the Department of Anatomy, Saveetha Dental College, Chennai for evaluation. With the help of Vernier Calliper, the measurements like the length between the anterior-superior iliac spine and mid iliac crest, length between the posterior-superior iliac spine and mid iliac crest and width of the iliac crest was measured. The results obtained were analysed, tabulated and represented graphically. The average distance between the anterior-superior iliac spine and mid iliac crest of pelvic bone in males and females was 57.11±1.32 and 59.23±0.68 respectively. The
average distance between the posterior-superior iliac spine and mid iliac crest of pelvic bone in males and females was 114.04±0.53 and 117.37±2.02 respectively. The average width of the iliac crest of pelvic bone in males and females was 16.40±0.65 and 18.75±1.32, respectively. Size of the iliac crest of pelvic bone was larger in females compared to males with regard to parameters taken for the study, therefore these parameters can be used for sex determination.
