This study was done on 65 isolated pelvic bones, These cadavers belonged to adult people of mature and old age, and they had no pathological changes. These measurements were performed on osteological collection of Department of Anatomy Drago Perović. Many geometrical parameters of facies auricularis were measured, which we considered important for further studies, simulations of joint's action, transfer calculations of the forces from spine to hip joint. We used paper, which partially adapted to the surface of facies auricularis, so the values are closer to real ones than projection values. The results have shown that the average surface of facies auricularis is 13.46 cm(2). There was no statistical significance found between left and right cadavers. For easier orientation we divided surface of facies auricularis into two parts: vertical and horizontal. Height of the vertical part was 3.99 cm, while the width was 2.05 cm. Height of horizontal part was 2.07 cm and the width 3.62 cm.
