BACKGROUND
Talus is a very important bone among the skeleton of foot. Talus is a very
common bone which undergoes some structural modifications due to prolonged
habitual squatting postures. Structural alterations like squatting facets, trochlear
extensions are observed over the dorsal aspect of the neck of the talus common
type of squatting facets observed are medial squatting facets, lateral squatting
facets, combined type of squatting facets .These are observed in specific group
of people.
METHODS
Present study was conducted in 100 talus bones, which are procured from
department of Anatomy, Andhra medical college, Visakhapatnam. Structural
modifications like squatting facets, trochlear extensions are studied in all the
bones.
RESULTS
Squatting facets are observed in most of the talus .but trochlear extensions are
not observed in any of the talus .out of 100 talus, 54 tali are having lateral
squatting facet, 4tali are having a medial squatting facet, 16 tali showing
combined type of squatting facet, 26 tali are not having any type of squatting
facets. Out of 54 right sided taluses, 24 tali are having a lateral squatting facet,
3 tali are having medial squatting facet, 10 tali are having combined type of
squatting facet, 17tali are not having any type of squatting facet. Out of 46 left
sided taluses, 30tali are having lateral squatting facet, 1 talus is having a medial
squatting facet, 6 tali are having combined type of squatting facets, 9tali are not
having any type of squatting facet.
CONCLUSIONS
Incidence of modifications over the neck of talus is very common in people who
are having a rural background, those people are having a habitual squatting
position. And these alterations may be due to genetic inheritance and several
unexplainable reasons.
