DefinitionDuring a bone graft, a donated piece of bone is added to the site of a fracture or other bone defect. The new bone can spur bone growth, bridge a gap in a bone, provide support, and aid in healing. The new bone may come from another part of your body (autograft) or from another person (allograft). Rarely, synthetic grafts, which are not bone, are also used.

Reasons for ProcedureA bone graft may be done to:
- Treat a fracture that is not healing
- Reconstruct a shattered bone
- Fill gaps in bone caused by cysts or tumors
- Fuse bones on either side of a joint
- Stimulate bone growth to help anchor an artificial joint or other implant
Possible ComplicationsProblems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Blood clots
- Nerve damage
- Rejection of a donor graft
- Anesthesia reaction
- Rarely, fat particles dislodge from the bone marrow and travel to the lung
- Chronic disease such as diabetes or obesity
What to Expect
Prior to ProcedureYour doctor will likely do the following:
- Physical exam
- X-rays of the bone involved
- Talk to your doctor about your medications. You may be asked to stop taking some medicationss up to 1 week before the procedure.
- Review with your doctor any herbs or supplements that you take. You may be asked to stop taking some.
- Do not eat or drink anything after midnight the day before your surgery, unless told otherwise by your doctor.
- Arrange for help at home after returning from the hospital.
AnesthesiaDepending on the procedure, you may receive:
- General anesthesia —You will be asleep.
- Local anesthesia—The area will be numbed.
Description of the ProcedureThe method of treatment depends on the type and location of the bone injury or defect and the type of graft you will be receiving.Most bone graft procedures use your own bone. The bone is often taken from the iliac crest. This is the bone at your hip, about where you would wear a belt. An incision is made over the part of the bone that will be removed. A special bone chisel will remove the piece of bone. This incision is then closed.An incision will be made in the skin covering the area in need of repair. Any scar or dead tissue will be removed from the area. Your bone will then be reconstructed with the graft. Plates and screws may be used during the procedure to immobilize the bone. A cast or brace may be needed after the procedure.
After ProcedureAn x-ray may be taken to make sure the bone is in the correct position.
How Long Will It Take?The length of your surgery will depend on the repair needed.
How Much Will It Hurt?Anesthesia prevents pain during the procedure. Pain and discomfort after the procedure can be managed with medication.
Average Hospital StayYour stay in the hospital will depend on the extent of surgery and your progress.
Post-procedure CareDuring your stay, the hospital staff will take steps to reduce your chance of infection such as:
- Washing their hands
- Wearing gloves or masks
- Keeping your incisions covered
- Washing your hands often and reminding visitors and healthcare providers to do the same
- Reminding your healthcare providers to wear gloves or masks
- Not allowing others to touch your incisions
- Do not smoke. Smoking can delay bone healing.
- Some grafts can fail. You doctor will track progress with x-rays.
