The newly formed soft bone that develops after a bone fracture and during the bone’s healing process. Bony callus may also refer to a thickening of the surface layer of the skin over a bony prominence, usually on the feet, but also on the hands. Such a callus usually forms in response to pressure. Symptoms include pain with pressure. In most cases, these do not require medical attention, unless they become very painful.
A proliferative development of fresh, pliable osseous tissue that emerges as a component of the reparative mechanism in a bone fracture. With the progression of the healing process, the callus undergoes substitution with more resilient bone, leading to the restoration of the bone’s initial form.
