A comminuted fracture of the heel bone does not always require bone grafting. If the bone mass of the articular surface of a relatively mild patient does not collapse, then conservative treatment can be chosen; if a more serious patient, the articular surface is accompanied by collapse and unevenness, then surgical bone grafting is required. The heel bone is cancellous bone, the fracture will be compressed, the fracture is more serious, will cause the articular surface collapse. In this case, bone grafting is required. If bone grafting is not done in time, it may cause abnormal stress on the arch of the foot and lead to traumatic arthritis. If the collapse of the articular surface is not obvious after a comminuted fracture of the heel bone, it can be treated conservatively with external immobilization in a cast to allow natural healing. It is recommended that patients with comminuted fractures of the heel bone should go to the hospital in time and follow the doctor’s advice to take appropriate methods of treatment.
