Morphological study of acetabulum on 3D model reconstructed from CT scan images for the southern Chinese population

Abstract

To obtain the morphological measurements of acetabulum for southern Chinese population, 40 volunteers were evaluated by CT scan. The 3D model of pelvis was reconstructed from CT scan images. The AVA, ABA and SID were measured for both sides. The mean AVA, ABA showed no significant difference for sex and both sides. But the SID showed the opposite results. The comparison of these parameters with western data were performed, and it indicated that there was significant different between our results and the data for western population published. This study may provide important reference in designing proper gender- and region- prosthesis for southern Chinese population.
