The variations in the talar articular facets on 401 normal Indian calcanei have been observed and classified. Type 1 calcanei have one continuous facet on the sustentaculum tali extending on the antero-medial corner of the distal part of the calcaneus (268 cases--67%). Type 2 calcanei have two articular facets, one on the sustentaculum tali, and another on the distal part of the calcaneus (104 cases--26%). Type 3 calcanei have a single well defined facet on the sustentaculum tali (21 cases--5%). Type 4 calcanei have a single facet on the sustenaculum tali extending on to the antero-medial corner of the distal part of the calcaneus, but this facet is continuous with the posterior talar facet of the calcaneus (8 cases--2%).
对401例正常印度跟骨的距骨关节面变异进行了观察和分类。1型跟骨在载距突上有一个连续的关节面，延伸至跟骨远端的前内侧角（268例，占67%）。2型跟骨有两个关节面，一个在载距突上，另一个在跟骨远端（104例，占26%）。3型跟骨在载距突上有一个清晰界定的单一关节面（21例，占5%）。4型跟骨在载距突上有一个单一关节面，延伸至跟骨远端的前内侧角，但该关节面与跟骨的后距骨关节面连续（8例，占2%）。
