Pattern of talar articular facets in Indian calcanei.
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%).
