Your bones heal after a fracture through a natural biological process involving several stages:
1. Inflammation (First Few Days)
Right after the fracture, blood vessels break and form a blood clot (hematoma) at the site.
This brings in immune cells to clean up debris and signals healing to begin.
2. Soft Callus Formation (Within a Week or Two)
Your body forms a soft callus made of collagen and cartilage, which bridges the broken bone ends.
3. Hard Callus Formation (Weeks to Months)
The soft callus is replaced by a hard bony callus made of new bone tissue (woven bone).
Specialized cells called osteoblasts build this new bone.
4. Bone Remodeling (Several Months)
The hard callus is slowly reshaped and strengthened into mature bone by osteoclasts (which break down excess bone) and osteoblasts.
Eventually, the bone regains its original shape and strength.
With proper care, such as immobilization (cast, splint) and nutrition (like calcium and vitamin D), most fractures heal completely.
, bone can grow back after it's broken or cut. When a bone breaks, your body starts healing right away. First, it forms a blood clot to protect the area. Then, soft tissue called a soft callus forms around the break. After that, special cells build new bone called a hard callus. Over time, this new bone gets stronger and reshapes to match the old bone. If the bone has a good blood supply and you take care of it, it can heal completely and be just as strong as before.
