Human calcanium; variations in the articular facets of the sustentaculum Tali

ABSTRACT

Sustentaculum tali is a projection at the apex of the longitudinal arch and thus occupies a key position in the subtalar joint. The articular facets of the sustentaculum tali have a variety of configurations. Objectives To study the variations of articular facets of the sustentaculum tali of the calcanium. Material and Methodss Total two hundred human calcanei were studied with naked eye obtained from the Anatomy department of the Punjab Medical College, Faisalabad and K.E. Medical College, Lahore. Results Type 1- 78.5% calcanei with long continuous facets. Type II - 13.5% calcanei with two facets and Type III - 8% calcanei with medial facets only. Conclusion The variations in the facets are due to different regions and races and may predispose people to subtalar joint instability
