本研究探讨了三维（3D）距舟关节（TNJ）覆盖/方向和骨形态，以揭示可以分类和识别高弓足和平坦足倾向的参数。根据计算机断层扫描图像生成40名受试者的65只足的3D模型，这些足部被分类为高凸足、中性排列或无症状/有症状的扁平足。我们计算了距骨和舟骨重叠（TNJ覆盖范围）。我们还测量了舟骨的方向，距骨和舟骨的形态参数，以及距骨头到身体的角位置。与无症状的扁平足（63 +/- 2%和95 +/- 2%）和中性排列的足（98 +/-2%舟骨）相比，高弓足显示出明显更少的距舟覆盖（58 +/- 2%距骨和86 +/-2%舟骨），并且相对于距骨，舟骨背屈和内收明显更多（P
This study explored three dimensional (3D) talonavicular joint (TNJ) coverage/orientation and bone morphology to reveal parameters that could classify and identify predispositions to cavus and planus feet. 3D models of 65 feet from 40 subjects were generated from computed tomography images classified as pes cavus, neutrally aligned, or asymptomatic/symptomatic pes planus. We calculated the talar and navicular overlap (TNJ coverage). We also measured orientation of the navicular, morphological parameters of the talus and navicular, and angular position of the talar head to body. Pes cavus showed significantly less talonavicular coverage (58 +/- 2% talus and 86 +/- 2% navicular) compared to asymptomatic pes planus (63 +/- 2% and 95 +/- 2%) and neutrally aligned feet (98 +/- 2% navicular), and significantly more navicular dorsiflexion and adduction relative to the talus (p
