Bone grafts
Bone Grafts
Bone grafts (pronunciation: /boʊn ɡræfts/) are surgical procedures that replace missing bone with material from the patient's own body, or with an artificial, synthetic, or natural substitute. The graft not only replaces missing bone, but also helps your body to regenerate its own bone. This new bone growth strengthens the grafted area by forming a bridge between your existing bone and the graft. Over time the newly formed bone will replace much of the grafted material.
Etymology
The term "bone graft" is derived from the Old English bān meaning "bone" and the Middle English graft meaning "something implanted".
Types of Bone Grafts
There are four main types of bone grafts:
- Autografts: Bone is taken from one site in the patient's body and moved to another site where it is needed.
- Allografts: Bone is taken from a donor and implanted in the patient.
- Xenografts: Bone from a non-human species, such as a cow, is used.
- Synthetic: Man-made materials are used to simulate bone.
Each type of graft has its own risks and benefits. The choice of graft material depends on the size and location of the defect, the health and preferences of the patient, and the surgeon's experience and preference.
