ABSTRACT:

Background and Aims: Calcaneum, also called as the “Heel Bone” is the largest and strongest tarsal bone in humans. It acts as the posterior pillar of the longitudinal arches of foot for the transmission of body weight. The Calcaneum articulates with the Talus bone superiorly by three articular facets, forming a Subtalar joint. In the present study, the variations of the Talar articular facets on the Calcaneum, presence of Calcaneal spur are observed along with morphometric analysis of Calcaneum.

Materials and Methods: 110 dry Calcaneal specimens from the Department of Anatomy of our institution are used for this study. Digital vernier caliper is used for morphometric analysis.

Observations: The Calcaneum is classified into different types based on the Talar articular facets. The presence of dorsal and plantar or inferior Calcaneal spur is observed and it is correlated with the different types of Calcaneum. Other morphometric parameters are also observed. The gender of the bone is not considered in the present study.

Conclusion: Subtalar joint stability is influenced by the morphology of Talar articular facets on the Calcaneum. Facet morphology can be determined by the gait pattern or other environmental and genetic factors. A proper knowledge of the anatomy of Calcaneum and their variations in different parameters is necessary for a good clinical understanding and treatment outcome.

Key words:  Calcaneum, Talar articular facets, Calcaneal spur.
