Synopsis

Avascular necrosis of the hip, also known as osteonecrosis of the femoral head, is an infarction of the bone due to disruption of blood flow. Patients present with a progressive limp or reduced range of motion at the hip. The amount of pain can vary substantially and is often referred to the knee.

Avascular necrosis of the hip can be unilateral or bilateral and can occur in adults or children. When it occurs in children, it is called Legg-Calvé-Perthes disease. Avascular necrosis of the hip may be secondary to trauma (fracture, dislocation) but also frequently occurs without trauma, making diagnosis more difficult. Common nontraumatic causes include alcohol abuse, corticosteroids, sickle cell disease, and autoimmune disease.

Avascular necrosis of the hip can lead to complete destruction of the bone and requires immediate specialist evaluation. Surgical interventions, such as osteotomy, decompression, or reconstruction, are typically required.
