Abstract
Introduction:The talus is a tarsal bone articulated with the tibia, fibula, navicular, and calcaneus bones to form supratalar, pretalar, and subtalar joints, respectively. A squatting facet is a kind of anomaly that forms on the surfaces where the tibia and talus articulate. The squatting facet states the daily activities and living style of society. Squatting is described as the hyperflexion of the hip and the knee and the movement of hyperdorsiflexion between the leg and the ankle. Materials and Methods: In the present cross‑sectional study, 600 dry adult human tali were taken from the osteology laboratory in the Department of Anatomy, King George’s Medical University, UP, Lucknow. Each talus was examined for the presence of various patterns of articular facets on the neck of the talus and extensions of its trochlear surface. Ethical clearance was obtained from the Institutional Ethics Committee, King George’s Medical University, Lucknow, as reference code: 121 ECMIIA/P3. Results: In our study, we observed that the lateral, medial, and combined squatting faces are 282 (47.64%), 49 (8.28%), and 22 (3.72%), respectively. Lateral, medial, and continuous trochlear extensions are 126 (21.12%), 120 (20.58%), and 31 (5.36%), respectively, in the Indian population. Conclusion: Modifications of the neck of the talus (squatting facets and trochlear extensions) are the result of prolonged squatting positions, which is a common habit of the Indian population, and incidences of these variations can be used as an anthropological marker for racial and regional differentiation of unidentified bones.
