Femoral head ischemic necrosis, also known as aseptic necrosis, is a common surgical disease caused by necrosis of the active components of the femoral head (bone cells, bone marrow cells, adipocytes, etc.) due to various causes of unilateral or bilateral impaired blood supply to the femoral head, with large doses of hormones, long-term uncontrolled alcohol consumption, and trauma being common causes. Progressive necrotic lesions of the femoral head can lead to collapse of the weight-bearing surface of the femoral head under pressure and loss of joint function. The clinical manifestations are pain around the hip joint and the front inner thigh to varying degrees, hip movement disorders, limb shortening and even loss of function. Stage 1 is characterized by painful symptoms but no imaging of femoral head necrosis; Stage 2 is characterized by varying degrees of pain around the hip joint and anterior medial thigh, impaired hip movement, and imaging of cystic changes in the femoral head, while the femoral head is intact and smooth and the hip joint gap is normal; Stage 3 is characterized by increased pain, significantly restricted hip joint function, and compression and collapse of the femoral head. In stage 4, the pain continues to worsen, the femoral head further collapses, the hip joint gap narrows and disappears, and the joint function is obviously restricted. The aim of clinical treatment is to reduce pain, restore hip joint motion function, and reduce or avoid limb deformity. Different treatment methods are suitable for different stages of development. For lesions above stage 4, artificial hip replacement should generally be the first choice, and for lesions within stage 3, internal conservative treatment can be chosen first. The core problem of ischemic necrosis of the femoral head is the impaired blood supply to the femoral head caused by various reasons. Regardless of the medical method, the goal is to improve the local blood circulation of the femoral head. Anatomically speaking, the blood supply arteries to the femoral head, femoral neck and hip joint are mainly the closed-space arteries from the internal iliac artery (in which the round ligament artery of the femoral head enters the femoral head directly) and the internal and external spinous femoral arteries from the beginning of the deep femoral artery. Interventional lysis is a new technique that combines interventional technology with Chinese and Western medicine drug treatment. Through the super-selective cannula of the above-mentioned small arteries, Chinese and Western medicines with the effects of dissolving thrombus, activating blood circulation, dilating blood vessels and improving microcirculation are directly injected into the blood supply artery of the femoral head. The purpose is to gradually resorb the necrotic bone, form new bone, and gradually repair the femoral head. A large number of cases have shown that interventional lysis can rapidly reduce or relieve pain, restore the function of the hip joint, and increase the hardness and bearing capacity of the femoral head in the near term, and effectively control the progress of the disease in the long term.
