Yes, bones can grow back after a break.
When a bone breaks, the body initiates a natural healing process. About two weeks after the fracture, specialized cells called osteoblasts migrate to the injury site and start building new bone. These osteoblasts add minerals to the developing bone, making it hard and strong. This stage, known as the hard callus stage, typically lasts for 6-12 weeks after the initial break. This process effectively bridges the broken pieces of bone, allowing it to heal.
In summary, the healing process involves:
- Inflammation: Initial response to injury.
- Soft Callus Formation: Cartilage forms around the fracture.
- Hard Callus Formation: Osteoblasts create new bone (typically 2 weeks after break, lasting 6-12 weeks).
- Remodeling: Bone is reshaped over time.
