What is avascular necrosis of the femoral head?

Avascular necrosis of the femoral head, also known as ischemic necrosis or aseptic necrosis of the femoral head, is an orthopedic condition primarily characterized by disruption of the blood supply to the femoral head, leading to bone tissue death. This condition commonly occurs in individuals between 40 and 60 years of age, although it can also affect children and adolescents.

Specific causes of avascular necrosis of the femoral head may include:

1. Trauma: such as fractures or hip dislocations, which can damage the blood supply to the femoral head.

2. Alcohol abuse: excessive alcohol consumption can damage blood vessels, reducing blood flow to the femoral head.

3. Decompression sickness: divers may encounter problems during rapid ascent, resulting in bubble formation in the bloodstream that can block blood supply to the femoral head.

Symptoms include hip pain, groin pain, limb shortening, difficulty walking, and limping, with the condition typically worsening over time. Treatment options for avascular necrosis of the femoral head include medication, traditional Chinese medicine therapy, surgical treatment, and other approaches.

If the above symptoms occur, it is recommended to seek medical examination at a hospital immediately.
