Osteonecrosis of the Femoral Head

Journal of the American Academy of Orthopaedic Surgeons, 1999
New cases of osteonecrosis of the femoral head in the United States number between 10,000 and 20,000 per year. This disease usually affects patients in their late 30s and early 40s. Although a number of authors have related specific risk factors to this disease, its etiology, pathogenesis, and treatment remain a source of considerable controversy. This

Osteonecrosis of the Femoral Head

Journal of the American Academy of Orthopaedic Surgeons, 2014
Osteonecrosis of the femoral head may lead to progressive destruction of the hip joint. Although the etiology of osteonecrosis has not been definitely delineated, risk factors include corticosteroid use, alcohol consumption, trauma, and coagulation abnormalities.

Osteonecrosis of the Femoral Head

Orthopedic Clinics of North America, 2019
Osteonecrosis of the femoral head most commonly arises from trauma or corticosteroid and alcohol use but is also associated with blood dyscrasias and metabolic and coagulation disorders. Initial evaluation includes a history and physical examination and plain radiographs. Early-stage osteonecrosis is best evaluated by MRI.

Osteonecrosis of the Femoral Head

2020
Osteonecrosis of the femoral head (ONFH) is a refractory disease caused by the disruption or impairment of blood supply to the femoral head. It is followed by the death of osteocytes and bone marrow as well as subsequent bone repair, which in turn leads to the structural changes and collapse of the femoral head, and joint dysfunction. Since Munro first

Nontraumatic Osteonecrosis of the Femoral Head

The Journal of Bone & Joint Surgery, 2006
The etiology of osteonecrosis of the hip may have a genetic basis. The interaction between certain risk factors and a genetic predisposition may determine whether this disease will develop in a particular individual. The rationale for use of joint-sparing procedures in the treatment of this disease is based on radiographic measurements and findings ...

MANAGEMENT OF OSTEONECROSIS OF THE FEMORAL HEAD

Orthopedic Clinics of North America, 1997
Osteonecrosis of the femoral head continues to pose a therapeutic challenge to orthopedic surgeons. This pathologic process results from the death of living components of bone from mechanical and biologic factors. Diagnosis, clinical symptoms, and classification systems are discussed.

Osteonecrosis of the Femoral Head

2017
Management of osteonecrosis of the femoral head is dependent on the stage of the disease and if there is collapse of the femoral head. Nonoperative management is rarely indicated, whereas core decompression with grafting can be a successful treatment method if used prior to collapse of the femoral head. For cases where subchondral collapse has occurred,
