Variations in talar facets on calcaneum and their clinical implications

Dr Nisha Yadav, Dr Dipti Nimje,Dr Kalpana Patil

Calcaneum is the longest, largest tarsal bone. The dorsal surface of calcaneum is having three facets i.e. anterior, middle and posterior. Facet variations are functionally important because they influence subtalar joint stability and suggest that the 2-facet configuration is more stable than the others. 70 calcaneal facets were studied. In that pattern I was predominant and found in 68.5%, pattern II in 21.4%, pattern III in 7.1%, pattern IV in 2.8% and none were of pattern V. Knowledge about variation is important for orthopaedicians while correcting foot deformities like pes planus. Therefore, this study is carried to identify patterns of talar facets on calcaneum and their clinical implications.
