A study of morphological pattern of the talar articular facets in dry human calcanei and its clinical implications

Background: The calcaneum is longest and largest of all the tarsal bone.  Morphology of the talar articular facets of calcanei is important for anatomy with respect to diagnosis and treatment of the injuries related to foot. Aims: This study was done to understand  the variation in the morphology  of talar articular facets on the superior surface of human calcanei and to study various shapes of these facets . Methods: 138 of adult dry calcanei 86 of right side and 52 of left side of unknown gender were taken from the museum of Department of Anatomy of Rohilkhand Medical College and Hospital, Bareilly and  LBKMCH,Saharsa and evaluated one by one. Result: PatternI was 69.5% of the studied bones, Pattern II and Pattern III were 4.3% each, Pattern IV was 21.7%, Pattern V was not found. The anterior and middle articular facets were mostly oval in shape and that of posterior articular facet was oval and convex.  The calcaneal length was recorded with  the mean and SD of 6.9 ± 0. 65cms (left side) and 6.9 ± 0. 9cm (right side). The width was 4.0 ± 0.38  cm (left) ,4.1 ± 0.3 cm (right).&nbsp
