Abstract

Pelvic bone is the representative bone which has the quite different features discriminating the sex. And these features are well described in almost all gross anatomy textbooks. The parameters which are used to sex determination are relating to the those of obstetrics. To suggest the most significant parameters for sex discrimination with the bones, we have selected the frequently mentioned 21 metric fields of non-pathologic Korean pelvic bones, which sexes were already confirmed (M: 40, F : 19). Measuring theses metric measurements, the statistic procedure (descriptive statistics and discriminant analysis) were performed (SASPC version 6.11). The parameters showing more than 80% of discriminating probability are the acetabular length (Martin No. 22) and the pubic angle(Martin No. 16). The parameters showing more than 75% of discriminating probability are the transverse diameters of pelvic outlet (Martin No. 27), the breadth of greater sciatic notch, the ischiatic length (Martin No. 15a), the pelvic breadth (Martin No. 2), the obturator foramen long length (Martin No. 20), the obturator foramen short length (Martin No. 20) and the pelvic height (Martin No. 1).
