Necrosis of the femoral head is caused by factors such as trauma, long-term use of glucocorticoids, chronic alcoholism, acute massive blood loss, and traumatic anemia. These factors lead to impaired circulation in the femoral head, resulting in its necrosis. Femoral head necrosis is also known as aseptic necrosis of the femoral head or ischemic necrosis of the femoral head. In terms of treatment for femoral head necrosis, the medical community both domestically and internationally generally considers it a challenging medical problem. Currently, treatments mostly involve traditional Chinese medicine for promoting blood circulation and removing blood stasis, decompression intervention, and late-stage femoral head replacement surgery, as well as massage. Traditional single-method treatments have poor efficacy, are lengthy in duration, and methods such as decompression intervention and femoral head replacement surgery are highly invasive, expensive, and cause great suffering to patients. According to statistics from experts at the University of Virginia in the United States, patients who undergo artificial femoral head replacement have a failure rate of approximately 10% to 50% within five years after surgery.
