The equine hoof can be divided into dorsal and palmar/plantar sections. The deformable soft tissue structures located within the palmar/ plantar section of the hoof capsule are the frog, frog corium, digital cushion, ungual cartilages and the deep digital flexor tendon. The function of these structures is to absorb concussion, dissipate the energy of impact and decrease the vibrations associated with the foot landing on the ground.
