Osteonecrosis of the femoral heads in Adult
Osteonecrosis of the femoral head can be unilateral or bilateral and can occur in adults or children. When it occurs in children, it is called Legg-Calvé-Perthes disease. Osteonecrosis of the femoral head 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.
Osteonecrosis of the femoral head can lead to complete destruction of the bone and requires immediate specialist evaluation. Surgical interventions, such as osteotomy, decompression, or reconstruction, are typically required.
