Abstract

The articular facets of the sustentaculum tali have a variety of configurations that are generally viewed as nonmetric traits of little functional significance. Bruckner (1987), in contrast, has hypothesised that sustentaculum tali facet variations are functionally important because they influence subtalar joint stability. To test this hypothesis, 191 calcanei were analysed for correlations between sustentaculum tali facet morphology and osteoarthritis of the subtalar joint. Calcanei with 2 separate sustentaculum tali facets had a lower frequency of arthritic changes associated with joint instability than calcanei with other facet configurations. This finding supports Bruckner's hypothesis that subtalar joint facet configuration is a factor in foot mobility.

摘要

距骨下支撑突的关节面有多种形态,通常被视为功能意义不大的非测量性状。相比之下,布鲁克纳(1987年)提出假说,认为距骨下支撑突关节面的变异具有重要功能意义,因为它们会影响距下关节的稳定性。为了验证这一假说,对191块跟骨进行了分析,以研究距骨下支撑突关节面形态与距下关节骨关节炎之间的相关性。与其他关节面形态的跟骨相比,具有2个独立距骨下支撑突关节面的跟骨,与关节不稳定相关的关节炎变化频率较低。这一发现支持了布鲁克纳的假说,即距下关节面形态是足部活动的一个因素。
