How do Bones Mend?

            Fractures are very common. A fracture is a break in a bone. Bones may break or fracture in several different ways. There are numerous types of features. A simple fracture is the one in which the two ends remain in position, and not much damage is done to the surrounding tissue. In a compound fracture, the broken ends of the bone pierce through the skin. In a fracture, the bone is splintered or shattered. An impact fracture involves the ends of two bones rubbing each other, whereas, a green stick fracture is a partial break of bone. In other kinds of fracture called a compound fracture, large blood vessels or nerves may be damaged, or the bone ends may be smashed.

A Bone gets Splintered or Shattered in a Fracture

            A fracture causes pain and inflammation in the area around it. Usually when a fracture occurs, a doctor must set the broken ends of the bone in the right position before bandaging or plastering, so that the bone may heal properly. A plaster cast is usually applied to the fractured limb in order to protect it from further impact and promote proper healing.

            The healing process begins when blood form broken blood vessels clots. After a few days, the broken ends of the bone become soft and the space between them is filled with sticky, glue-like substance that contains bone-forming cells.

            Within three or four weeks, new soft bone tissues completely fill the gap between the broken ends, and this congealed lump known as a callus gradually hardens into bone. The complete healing of a fracture may take several weeks. The only necessary condition is that the two broken pieces must be held in place over this long period so old age, bones become brittle and tend to fracture more easily.
