How Bones Heal

Choose a preferred language

Bone is living tissue made up of cells. When a bone breaks, bleeding, swelling, and blood clotting happen in the injured area. As the bone heals, the clotted blood is replaced with fibrous tissue and cartilage.

Bones heal through a slow process called remodeling. This is when the bone continues to form and becomes compact. The length of this process depends on your general health and age. It also depends on the type of break and how serious it is.

Other things that affect healing include:

  • Medicines you take

  • If you smoke. Smoking delays bone healing.

  • How well the injury is cared for

Bones usually take about 6 to 12 weeks to heal.

Common Types of Fractures

Bones anywhere in the body can break. Casts are often used for fractures in the hands, arms, legs, or feet. There are many types of fractures. But all fractures heal the same way: New bone grows to connect the broken pieces. A cast holds broken bones in place while they heal.
