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.

中国南方人群髋臼三维CT重建模型的形态学研究
为了获得中国南方人群髋臼的形态特征,对40名志愿者进行了CT扫描。根据CT扫描图像重建骨盆三维模型。测定双方的AVA、ABA和SID。平均AVA、ABA在两性间无显著差异。但SID显示出相反的结果。将这些参数与西方的数据进行比较,发现我们的结果与西方已发表的人群数据有显著差异。本研究可为设计适合南方人群的性别和地域义肢提供重要参考。
