Answer:
Fracture healing is a biological process in continuum from fracture to healed stage. It involves a sequence of dynamic events which ultimately restores the integrity of the bone and its biomechanical properties.1 Bone is the only biological tissue which heals by making bone and the rest of the tissues heal by making a different tissue.
