The heel bone is responsible for the fulcrum of the longitudinal arch of the foot and forms the inferior talar joint with the talus bone, and the heel dice joint and heel navicular joint with the dice bone and navicular bone. The main role of the heel bone is to maintain normal weight bearing and to assist the patient to complete jumping movements. The heel bone is susceptible to trauma, resulting in a comminuted heel fracture, which can affect weight-bearing function. A broken heel bone can be easily detected by taking x-rays. Early surgical fixation and bone grafting treatment can gradually heal the heel bone, but ischemic necrosis of the heel bone may also occur, leading to serious effects on eventual lower limb function. Therefore, care should be taken to protect the heel bone in general to avoid falls from heights that can cause serious damage to the heel bone.
