In many cases, the physician can make a diagnosis and recommend a course of treatment based on a patient's health history and a physical exam.īut for some patients, imaging studies may be recommended in order to precisely determine the source of the pain, make a diagnosis, and gain important information about the condition. Total hip replacement is successful in relieving pain and restoring function in the majority of patients with osteonecrosis.Determining the cause of hip pain usually starts with a visit to the family doctor, internist, or orthopedist. In this situation, the patient is best treated with a total hip replacement. When osteonecrosis is diagnosed after collapse of the bone, core decompression is not usually successful in preventing further collapse. If a vascularized fibular graft is performed prior to femoral head collapse, the clinical outcomes are usually favorable. ![]() Typically, you are non-weightbearing for the first several weeks you will then gradually start weightbearing with an ambulatory assistive device (walker or cane). Vascularized fibular grafting is an invasive procedure that requires several months of healing. Patients with successful core decompression procedures typically return to walking unassisted in about 3 months and may have complete pain relief. It takes a few months for the bone to heal and, during this time, you will need to use a walker or crutches to avoid putting stress on the damaged bone. In some of these cases, the bone heals and regains its blood supply after core decompression. This depends upon the stage and size of the osteonecrosis at the time of the procedure.Ĭore decompression achieves the best results when osteonecrosis is diagnosed in its early stages, before the bone collapses. This graft is transplanted into a hole created in the femoral neck and head, and the artery and vein are reattached to help heal the area of osteonecrosis.Ĭore decompression prevents osteonecrosis from progressing to severe arthritis and the need for hip replacement in some cases. In this procedure, a segment of bone is taken from the small bone in your leg (fibula) along with its blood supply (an artery and vein). Vascularized Fibula GraftĪnother surgical option is a vascularized fibula graft. It is importat to speak with your surgeon about the available options that may be used for your procedure. Sometimes, your own bone marrow cells may be mixed together with the graft substitute to help in the bone regeneration process. There are also several synthetic bone grafts available today. The tissue may be taken from a donor (allograft) or from another bone in your body (autograft). A bone graft is healthy bone tissue that is transplanted to an area of the body where it is needed. (Right) In this X-ray, the drill lines show the pathway of the small drill holes used in the procedure.Ĭore decompression is often combined with bone and cartilage grafting to help regenerate healthy bone and support cartilage at the hip joint. (Left) Illustration of core decompression. Osteonecrosis is associated with other diseases, including Caisson disease (diver's disease, or "the bends"), sickle cell disease, myeloproliferative disorders, Gaucher's disease, systemic lupus erythematosus, Crohn's disease, arterial embolism, thrombosis, and vasculitis. ![]() ![]() ![]() Although it is not known exactly why these medications can lead to osteonecrosis, research shows that there is a connection between the disease and long-term corticosteroid use. Many diseases, including asthma, rheumatoid arthritis, and systemic lupus erythematosus, are treated with steroid medications. Overconsumption of alcohol over time can cause fatty deposits to form in the blood vessels and can elevate cortisone levels, resulting in a decreased blood supply to the bone. Hip dislocations, hip fractures, and other injuries to the hip can damage the blood vessels and impair circulation to the femoral head. It is not always known what causes the lack of blood supply, but doctors have identified a number of risk factors that can make someone more likely to develop osteonecrosis: In osteonecrosis, the bone in the head of the femur slowly dies. ![]()
