How long can a person live with avascular necrosis of the femoral head?

Osteonecrosis of the femoral head, also known as avascular necrosis or aseptic necrosis of the femoral head, is an orthopedic condition primarily caused by insufficient blood supply to the femoral head, leading to bone cell death. This disease does not directly affect life expectancy, and patients can generally live a normal lifespan. If left untreated, the condition may progressively worsen, causing joint pain, functional impairment, and potentially requiring joint replacement surgery.

1. Early-stage patients: Patients diagnosed and treated early generally have a better prognosis. Most patients can return to normal life through conservative drug therapy or surgical treatment, with minimal impact on survival duration.

2. Late-stage patients: If osteonecrosis progresses to an advanced stage with severe femoral head collapse, muscle atrophy, or other serious complications, treatment becomes more challenging and postoperative recovery may be difficult. However, the condition does not pose a direct threat to life.

It is recommended to visit a regular hospital and follow the guidance of qualified physicians for appropriate management.
