Necrosis of the femoral head is caused by impaired circulation in the femoral head due to factors such as trauma, long-term use of glucocorticoids, chronic alcohol abuse, acute massive blood loss, and traumatic anemia. Necrosis of the femoral head is also known as aseptic necrosis of the femoral head or ischemic necrosis of the femoral head. The treatment of femoral head necrosis is generally considered to be a challenging medical problem by the medical community both domestically and abroad. Currently, treatments mostly involve traditional Chinese medicine for promoting blood circulation and removing blood stasis, decompression intervention, late-stage femoral head replacement surgery, and massage. Traditional single-method treatments have poor effects, are lengthy, and methods like decompression intervention and femoral head replacement surgery are highly invasive, expensive, and cause great pain to patients. According to statistics by experts from the University of Virginia in the United States, about 10% to 50% of patients who have undergone artificial femoral head replacement fail within five years after surgery.
