provides a pumping action to return blood to the foot
A nail through the apex of the frog (cranial)…
may enter the navicular bursa.
A puncture through the base (palmar)…
may enter the digital cushion and will puncture the DDF tendon associated with the tendon sheath, which can lead to an infection of the digital tendon sheath.
