背景：尽管进行了大量的研究，但对距肢关节轴尚无共识。本研究的目的是一种确定距骨关节几何旋转轴的新方法。方法：对98例高加索人全肢ct扫描结果进行分析。我们制作了距骨的三维重建模型。最佳拟合锥体定位于距骨关节面。几何旋转轴被定义为这个圆锥的轴。结果：距踝关节的几何旋转轴从外侧远端到内侧近端（与解剖胫骨轴在扭转面85.6度+/- 10度相比），从后远端到前近端（与解剖胫骨轴在矢状面81.43度+/- 44.35度相比），从后内侧到前外侧（与轴向面踝间轴相比169.2度+/- 5.91度）。结论：考虑我们的结果可能有助于更好地理解踝关节生物力学。(c) 2018年欧洲足部和脚踝协会。Elsevier Ltd.出版。版权所有。
Background: Despite intensive research there is no consensus about the talocrural joint axis. The aim of the present study is a new method to determinate the geometric rotational axis of the talocrural joint.Methods: We analyzed 98 CT-scans of full cadaver Caucasian legs. We generated three-dimensional reconstruction models of the talus. A best fitting cone was orientated to the talar articular surface. The geometric rotational axis was defined to be the axis of this cone.Results: The geometric rotational axis of the talocrural joint is orientated from lateral-distal to medial-proximal (85.6 degrees +/- 10 compared to anatomical tibial axis in torsional plane), from posterior-distal to anterior-proximal (81.43 degrees +/- 44.35 compared to anatomical tibial axis in sagittal plane) and from posterior-medial to anterior-lateral (169.2 degrees +/- 5.91 compared to intermalleolar axis in axial plane).Conclusions: The consideration of our results might be helpful for better understanding of ankle biomechanics.
