BACKGROUND The calcaneum is the largest and strongest bone of all tarsal bones. It articulates above with talus to form talocalcaneal joint. In the middle third of superior surface, there is an oval shaped posterior articular facet which articulates with the body of talus. In the anterior third of superior surface, there are anterior and middle facets for the articulation of head of talus. Aim of the present study is to determine the variations of articular facets in population of Bihar and its clinical implications. MATERIALS AND METHODS This is a descriptive study which was conducted on human calcaneal articular facets in the Department of Anatomy from September 2016 to May 2017. 200 dry adults' human calcanei were obtained from Indira Gandhi Institute of Medical Science, Patna; Vardhman Institute of Medical Sciences, Pawapuri; Nalanda & Darbhanga Medical College, Laheriasarai; and also from undergraduate students. RESULTS In this study, we found the 3 major types based on the separation of articular facets on superior surface i.e. type A, B & C. In this study, type B was most common (54%) in which Type B1 was commonest with fused anterior and middle facets without constriction. Type C was rarest variety of pattern. CONCLUSION This study reveals that configuration of articular facets influences the stability of subtalar joint. KEYWORDS Calcaneum, Facets for the Talus, Pattern, Variation.
