![]() As time goes on, the patient's bone replaces the cadaver bone. ![]() Like a traditional bone graft, it provides scaffolding for the patient's bone to heal across the area of the nonunion. An allograft (cadaver) bone graft avoids harvesting bone from the patient, and therefore, decreases the pain involved with treating the nonunion. Although harvesting the bone may be painful, the amount of bone removed usually does not cause functional, structural, or cosmetic problems.īone graft is taken from the back of the pelvis and placed at the nonunion site. The rim of the pelvis or "iliac crest" is most often used for harvesting bone. These are then transplanted to the nonunion site. Bone grafts also provide fresh bone cells and the naturally occurring chemicals the body needs for bone healing.ĭuring the procedure, a surgeon makes an incision and removes (harvests) pieces of bone from different areas on the patient. A bone graft provides a scaffold on which new bone may grow. During this procedure, bone from another part of the body at the fracture site to "jump start" the healing process. Surgical options include bone graft or bone graft substitute, internal fixation, and/or external fixation. You may also need a second surgery if the first surgery failed. Surgery is needed when nonsurgical methods fail. In addition, the injury can destroy the internal blood supply found in the marrow at the center of the bone.Īn external bone stimulator is applied to the skin overlying the nonunion. For example, a high-energy injury can damage the skin and muscle over the bone and destroy the external blood supply. Some bones, such as the shinbone (tibia), have a moderate blood supply, however, an injury can disrupt it.The blood supply can be destroyed when these bones are broken. Some bones, such as the upper thighbone (femoral head and neck) and small wrist bone (scaphoid), have a limited blood supply.They can be expected to heal with minimal treatment. Some bones, such as toe bones, have inherent stability and excellent blood supply.Nonunions are more likely to happen if the injured bone has a limited blood supply. A complicated break that is open or compound.The physician and patient should always discuss the risks and benefits of using these medications during fracture healing Medications including anti-inflammatory drugs such as aspirin, ibuprofen, and prednisone.Use of tobacco or nicotine in any form (smoking, chewing tobacco, and use of nicotine gum or patches) inhibits bone healing and increase the chance of a nonunion.Several factors increase the risk of nonunion. They also are more likely if the bone breaks from a high-energy injury, such as from a car wreck, because severe injuries often impair blood supply to the broken bone. Nonunions happen when the bone lacks adequate stability, blood flow, or both. In this case, the doctor will discuss dietary guidelines and make recommendations for adding dietary supplements.) (The rare exception is the severely malnourished patient with many injured organs. Eating a healthy and well-balanced diet that includes protein, calcium, vitamin C, and vitamin D is the best way to ensure adequate nutrition dietary supplements that go beyond the daily requirements are not effective. A broken bone also needs adequate nutrition to heal. The blood supply to the injured bone usually comes back on its own during the healing period.Ī broken bone stabilized with a plate and screws. These include oxygen, healing cells, and the body's own chemicals necessary for healing (growth factors). Blood delivers the components required for healing to the fracture site. Some fractures require surgical fixation with devices like screws, plates, rods and frames. Some fractures can be held in position with a cast. All treatment of broken bones follows one basic rule: the broken pieces must be put back into position and prevented from moving out of place until they heal. ![]() Good nutrition also plays a role in bone healing. For bone healing to happen, the bone needs adequate stability and blood supply. ![]()
