At the talocrural joint, two convex ridges of the trochlea of the talus articulate with two reciprocal concave grooves of the cochlea of the tibia.
How does a dorsoplantar image of a tarsus work?
For the dorsoplantar projection, the area of interest is imaged in a dorsal to plantar direction, which positions the affected limb against the cassette/detector or table and reduces magnification and geometric distortion. Figure 2. Dog positioned for dorsoplantar images of the tarsus (A) and corresponding radiograph (B).
Where are the metatarsal bones located on a dog?
