What is the bump after fracture?
A callus is a mass of new bone tissue that forms around a fractured bone to help it heal. The callus starts to form within a few days of a fracture and continues to grow for several weeks. It is made up of several different types of cells, including osteoblasts, osteocytes, and chondroblasts. Osteoblasts are cells that build new bone tissue, while osteocytes are mature bone cells that help to maintain the bone. Chondroblasts are cells that produce cartilage, which is a type of tissue that is found in joints and between bones.
The callus provides stability to the fractured bone and helps to protect it from further damage. It also provides a pathway for blood vessels and nerves to grow into the fractured bone, which is necessary for the bone to heal properly.
The size of the callus depends on the severity of the fracture. A small fracture may only produce a small callus, while a more severe fracture may produce a large callus. The callus will also usually appear larger in children than in adults, because children's bones are still growing and developing.
In most cases, the callus will eventually be reabsorbed by the body as the bone heals. However, in some cases, the callus may remain visible or even grow larger over time. This can be a sign of a problem with the healing process and may require further treatment.
