Abstract

Aim: To study the various morphometric parameters of the dry sacra of unknown sex in South Indian population in detail and to determine their demarcating points in order to increase the efficiency of sexing in the given population.
Methods:  87 dry adult human sacrum of known sex (42 males and 45 females), belonging to South Indian (Karnataka) region were obtained. Various parameters like Length (L), breadths (B), Transverse diameter of the body of the 1st sacral vertebrae (TS1) & Curved Length of Sacrum (CL) were obtained. From these parameters, Sacral Index (SI), Curvature Index (CI) and Corporo-basal Index (CBI) were calculated & from the obtained values demarking points (D.P) were calculated. The values were stastically analyzed.
Results:  Among these parameters, the values for the Length (L), Curved Length (CL) and Sacral Index (SI) were stastically significant
Conclusion: Length (L), Curved Length (CL) and Sacral Index (SI) were useful parameters and by obtaining their demarking points, it helps in sexing the sacrum with greater accuracy.  
KEY WORDS:  Sacrum, Sexing, Morphometry, Sacral Index, Karnataka.
