It can be divided into gap healing and contact healing. Gap healing is initialized by woven bone filling the fissure, with no connective tissue or fibrocartilage. Next, the remolding stage occurs, where osteon substitutes the new bone and the fractures ends. Contact healing, on the other hand, happens when there is direct contact between the two fractures ends and osteons can grow through the area. What happens during this process is that osteoblasts on one end undergo reabsorption and create cutting cones across the break. This process promotes a cavity, which aids in the formation of blood vessels that work endothelial cells and osteoprogenitor cells that help form osteon from osteoblasts (Lieberman & …show more content…
The therapy entailing the release of human’s own stem cells into the blood has been determined a new way to help the body repair itself and was founded by a group of British scientists. It has already been known that bone marrow releases stem cells when the body is injured that creates fresh blood to help patients suffering from blood cancer. Sarah Rankin of Imperial College has discovered a way to get marrow to release another kind of stem cell aimed to repair bones, as well as blood vessels and cartilage. Her research done on mice, include a drug called mozobil, included with a natural growth factor, can increase the amount of the stem cell in blood by a hundred. This technique can be a way to speed up sever bone breaks
