Abstract

Pelvic bone is the major bone which has the quite different features between male and female. And these features are well described in almost all gross anatomy textbooks. The parameters which are used to sex determination are related with 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, whose sexes were already confirmed (M 40, F 19). For measuring these metric parameters, the statistic procedure (descriptive statistics and discriminant analysis, group analysis) was performed (SAS PC version 6.12). The parameters showing more than 80% of discriminating probability are the acetabular length (Martin #22) and the pubic angle (Martin #16). The parameters showing more than 75% of discriminating probability are the transverse diameters of pelvic outlet (Martin #27), the breadth of greater sciatic notch, the ischial length (Martin # 15a), the pelvic breadth (Martin #2), the obturator foramen long length (Martin #20), the obturator foramen short length (Martin #20), and the pelvic height (Martin #1). All the metric parameters could be categorized into 5 groups.
