Osteonecrosisoffemoralhead (ONFH) is an osteonecrosis of the femoral head and certain anatomical areas, and is a disease caused by a variety of factors. The common pathological feature of ONFH is the destruction of the blood supply around the femoral head, resulting in insufficient or interrupted blood supply to the femoral head, injury to the nourishing blood vessels, loss of nutrition to the femoral head, and eventually bone degeneration and necrosis, fracture and collapse of bone trabeculae, and hip dysfunction. There is a high clinical incidence, and mostly seen in young and middle-aged patients, belonging to the common and difficult to treat bone and joint diseases. Without effective intervention in the early stages of ONFH, most patients will generally develop femoral head collapse in 1-4 years, and then have to undergo artificial hip replacement. Because of the limited service life of the artificial total hip joint, patients face secondary hip replacement and revision after hip replacement, which creates a heavy physical, mental and economic burden for patients and families. If active and effective treatment can be carried out in the early stage, i.e. before the deformation and collapse of the femoral head occurs, it can relieve the patient’s pain symptoms and delay the occurrence of femoral head collapse as much as possible, thus delaying the replacement of the artificial total hip joint, which will have significant social and economic benefits. Therefore, active and effective treatment should be taken at an early stage to alleviate or change the natural course, and ultimately to preserve the patient’s own femoral head or delay the time of artificial joint replacement.
