Research on biomechanics of the ankle and foot has demonstrated a complex pattern of load distribution through the ankle joint.
Investigating possible relationship between articular dimensions, angular parameters and overall talar morphology.
Two linear dimensions, six articular surfaces and three angular parameters were measured from dried human talar bones (left=60; right=82). Angular parameters were measured at the neck of the bone (junction of the head and the body). Correlation and co-variation were worked out between the values of surface area parameters and the angular orientations measured from all the samples in context of load transmission across the talus.
The total trochlear surface area of the talus totaled approximately equal to the sum of areas at the head and the lower surface of the talus. The vertical angle showed a strong correlation with the articulating surface area below the head of the talus in contact with the spring ligament.
Articular surface areas as well as the angular orientations of talar components vary with the magnitude of stress subjected to the bone. The inter-relationship between articular and angular parameters within the talus demonstrates strong correlation for certain parameters.
踝关节和足部的生物力学研究表明，通过踝关节的负荷分布模式复杂。
研究关节尺寸、角度参数与距骨整体形态之间的可能关系。
从干燥的人体距骨（左侧60块；右侧82块）测量两个线性尺寸、六个关节面和三个角度参数。角度参数在骨颈部（头部与身体的交界处）测量。在距骨上负荷传递的背景下，计算所有样本的表面积参数值与测量的角度方向之间的相关性和协变性。
距骨的总滑车表面积大致等于距骨头和下表面面积之和。垂直角与距骨头下方与弹簧韧带接触的关节表面积呈强相关。
距骨各组成部分的关节表面积和角度方向随骨骼承受的应力大小而变化。距骨内关节参数和角度参数之间的相互关系表明某些参数具有强相关性。
