Ashwini Ramesh Anwikar, Santoshkumar A. Dope, Mangesh S. SelukarBackground:
Identification of sex by human skeletal remains a critical problem and is very important in anthropological and medico-legal works. Bones often survive the process of decay and therefore provide the major evidence of human age and sex after death. Over the years, different authors had carried out various types of measurements on human sacra of different races and regions.
Materials and Methods:
The present study was carried out on 68 sacra of unknown sex, which, after identification by physical characteristics, contain 37 male and 31 female sacra. They were collected from the Marathwada region of Maharashtra, India.
Results:
In the present study, the mean sacral index in males was 100.31 and in females, 107.70. The male mean sacral index value of the present study was more than the values of the Eastern part, the North part and studies of the Southern part of India and other western parts, except in the Western Rajasthan population. The female mean sacral index value of the present study was higher than the observations of the Eastern part, studies of the Southern part of India, and lower than that of north part of India and other regions of the western part of India.
Conclusion:
The studies on the Indian population suggest that the mean sacral index in females is higher than that of males.
