Bone Grafts

You might need bone grafting to promote bone healing and growth for a number of different medical reasons. Some specific conditions that might need a bone graft include:

• An initial fracture that your healthcare provider suspects won’t heal without a graft
• A fracture that you previously did not have treated with a graft and that didn’t heal well
• Diseases of the bone, such as osteonecrosis or cancer
• Spinal fusion surgery. You might need this if you have an unstable spine.
• Dental implant surgery. You might need this if you want to replace missing teeth.
• Surgically implanted devices, such as total knee replacement, to help promote bone growth around the structure 

These bone grafts can provide a framework for the growth of new, living bone. Hips, knees, and spine are common locations for bone grafting, but you might need bone grafting for a different bone in your body.

Talk with your healthcare provider about whether you want to use a bone from a donor or a bone from elsewhere in your body. If you use your own bone, you will have to have extra surgery to remove this bone. You won’t need this if you use donated bone, but donated bone has its own small risks. Talk with your healthcare provider about what makes sense for you.

Bone grafting is generally safe, but it does have some rare risks, such as:

• Infection
• Bleeding
• Blood clot
• Nerve damage
• Complications from anesthesia
• Infection from the donated bone (very rare) 

There is also a risk that your bone might not heal well even with your bone graft. Many of your specific risks will vary according to the exact reason for your bone graft. These reasons include whether or not you are using donor tissue, your other medical conditions, and your age. For example, your bone graft might not be as likely to heal well if you smoke or if you have diabetes. Talk with your healthcare provider about all your concerns, including the risks that most apply to you.

Talk with your surgeon about how to prepare for your bone graft surgery. Ask whether you should stop taking any medicines ahead of time, like blood thinners. If you are a smoker, try to stop smoking before your procedure to help speed healing. Tell your surgeon about all the medicines you take, including any over-the-counter medicines like aspirin. Also, tell your healthcare provider about any changes in your overall health, like a recent fever.

Before your procedure, you may need additional imaging tests, like X-rays, CT scan, or MRI.

You may need to make additional arrangements ahead of time, depending on the reason for your bone grafting. For example, if you won’t be able to put weight on your leg after your surgery, you may need to rearrange your living arrangements.

Don’t eat or drink after midnight the night before your procedure.

The details of your bone grafting surgery will vary a great deal according to the reason for your surgery. Ask your healthcare provider about the details of your particular surgery. An orthopedic surgeon will do your procedure aided by a team of healthcare professionals. As an example, you might expect:

• You will get anesthesia to make sure that you won’t feel any pain or discomfort during the procedure.
• Someone will carefully keep track of your vital signs, like your heart rate and blood pressure, during the operation.
• After cleaning the affected area, your surgeon will make a cut through the skin and muscle surrounding the bone that will receive the bone graft.
• In some cases, your surgeon will also make a different cut to harvest your bone graft. This might be from your hipbone, leg bone, or ribs. Using special tools, your surgeon will remove a small portion of bone.
• Your surgeon will insert the bone graft between the two pieces of bone that need to grow together. In some cases, your surgeon might secure the bone graft with special screws, rods, or plates.
• Your surgeon will make any other needed repairs.
• The layers of skin and muscle around your treated bone will be closed surgically and, if needed, around where your bone was harvested.

Talk with your surgeon about what you can expect after your surgery. You may have some pain after your procedure, but pain medicines may help relieve the pain. You should be able to resume a normal diet fairly quickly. You may get some imaging, like an X-ray, to make sure your surgery was successful. Depending on the extent of your injury and your other medical conditions, you might be able to go home the same day.

Your surgeon will give you detailed instructions about how you can move the area that received the bone graft. This usually involves keeping the area immobile for a while. This might need a splint or a brace. You’ll also probably need to stay away from putting weight on the area. You may need physical therapy to restore strength and flexibility to your muscles.

You might need to take medicines to prevent blood clots (a “blood thinner”) for a little while after your surgery. Your healthcare provider might not want you to take certain over-the-counter medicines for pain. Some of these can interfere with bone healing. Your healthcare provider may advise you to eat a diet high in calcium and vitamin D as your bone heals. If you smoke, your surgeon may also advise you to stop smoking. Smoking may interfere with bone healing.

You might have some fluid draining from your incision. This is normal. But let your surgeon know right away if the draining is severe. Also let your surgeon know if your wound has increased redness or swelling, or if you have severe pain, loss of feeling, or a high fever or chills.

Make sure to keep all of your follow-up appointments. You may need to have your stitches or staples removed a week or so after your surgery. Your surgeon may want to do a series of X-rays to see how well your bone heals. Follow all your healthcare provider’s instructions carefully to have the best chance at full recovery.
