A graft is an artificial implant that replaces or supports a damaged or missing body part. It is usually made from a material that is compatible with the body, such as metal, plastic, ceramic, or bone.
Grafts can be used to replace parts of the bones, joints, blood vessels, skin, and other tissues. They are commonly used to treat injuries and conditions such as skeletal fractures, joint damage, vascular disease, and skin burns.
In some cases, a graft may be needed to support surrounding tissue during healing. For example, a skin graft may be used to cover a large area of burned skin. A bone graft may be used to fill in gaps in bones that have been damaged by trauma or disease.
Grafts are typically removed once the healing process is complete. In some cases, however, they may be permanent.
