Trochlea of talus - Trochlea tali
The superior surface of the body of talus presents, behind, a smooth trochlear surface, the trochlea of talus, for articulation with the tibia. The trochlea is broader in front than behind, convex from before backward, slightly concave from side to side: in front it is continuous with the upper surface of the neck of the bone.
