The treatment methods of hip femoral head necrosis include the following: First, non-surgical treatment, which is suitable for adolescent patients, because they have better potential self-repair ability, and with the growth and development of adolescents, the femoral head can often be altered to obtain satisfactory results. Non-surgical treatment can also be used for adults with stage I and II lesions, and the smaller the extent of the lesion, the easier it is to repair. For unilateral hip lesions, weight bearing should be avoided on the side of the lesion, and walking with crutches, sciatic braces and walkers is possible. If both hips are involved at the same time, the patient should be bedridden or in a wheelchair. If the hip pain is severe, the patient can be bedridden and have traction on the lower limbs at the same time, which can often relieve the symptoms. Physical therapy can relieve the symptoms, but it lasts longer, usually 6-24 months or more. Secondly, surgical treatment, if conservative treatment is not effective, surgical treatment can be performed instead, such as medullary core decompression, bone grafting and artificial hip replacement.
