    The body is able to fix itself and the body’s healing process begins almost immediately after the break. The body forms a blood clot called a fracture hematoma that stabilizes the bone and gets it ready to begin the mending process. At this point, the hematoma becomes a soft callus where calcium is deposited to help rebuild the bone. Next osteoclasts (cells responsible for break down of bone) and osteoblasts (cells responsible for formation of bones) move in and the callus becomes bone callus. A hard shell is formed, which provides protection and stability for the bone as it enters its final stage of healing, which is to remodel the bone and return it to its original shape. 

    Doctors work with the body to create the best healing conditions possible but it takes time to heal a broken bone. In most cases, once the bone has healed and you return to your normal activities the bone returns to its former strength.

    People tend to think of bones as solid, lifeless matter. But your skeleton, like softer tissues and organs, is a living part of your being. Your bones change constantly.

    Osteoclasts break down bone, then osteoblasts replace it with new bone tissue in a process referred to as bone remodeling. Chondroblast, another type of cell, forms new cartilage.

    Bone remodeling doesn't just happen early in life. It is constant. During the course of months, it replaces old bone tissue with new.
