First, the cause of femoral head necrosis: Femoral head necrosis (English abbreviation, ONFH), also known as ischemic necrosis of the femoral head (AVNFH), refers to a variety of causes caused by the interruption of the blood supply of bone caused by the death of bone cells and bone marrow components, and then (may) lead to structural changes in the femoral head caused by collapse (pain) and dysfunctional disease, is a common orthopedic disease. Femoral head necrosis can occur after trauma to the hip joint or after long-term, heavy use of hormones and long-term alcohol abuse. Ischemic necrosis of the femoral head is most common between the ages of 30 and 60 years, and 70% of patients have bilateral head necrosis. The main clinical symptom is hip pain, which is chronic and dull, but can also be acute and radiates down to the femur, hip and medial knee, with the most obvious pain at night. The pain is most pronounced at night. Later on, the symptoms worsen and claudication occurs. The causes of insufficient blood supply to the femoral head are: 1. interruption of blood flow in the femoral head due to bone neck fracture or hip dislocation; 2. obstruction of small vessel embolic deposits caused by sickle cell disease, pancreatitis, decompression disease, etc.; 3. vasculitis, hip infection (hip or femoral osteomyelitis, septic hip osteoarthritis, hip tuberculosis, radiation, long-term use of hormones, alcoholism, etc. causing vascular occlusion. Second, the conventional conservative and surgical treatment: early diagnosis of femoral head necrosis is difficult, and the prognosis is poor. High disability rate, seriously affect the quality of life, bring great economic and mental pressure to the family and society. Usually, there are two types of treatment for patients who have been diagnosed with femoral head necrosis: conservative and surgical. Protective weight-bearing: such as using double crutches can effectively reduce the pain and the burden on the hip joint, but the use of wheelchairs is not advocated. Reduce climbing, hiking, going up and down stairs, carrying heavy objects and other behaviors that strengthen the pressure on the hip joint. Drug treatment: Applicable to early stage (0, I, II) ONFH, non-steroidal anti-inflammatory and pain relieving agents can be used, for high coagulation and low fibrinolytic state, low molecular heparin and corresponding traditional Chinese medicine can be used, such as sodium alun phosphate can prevent femoral head collapse, vasodilator drugs also have certain efficacy. Physical therapy: including extracorporeal shock wave, high-frequency electric field, hyperbaric oxygen, magnetic therapy, etc., which are beneficial to relieve pain and promote bone repair. Surgical treatment of femoral head necrosis: Most patients with ONFH will face surgical treatment, which includes two major types of surgeries: preserving the patient’s own femoral head and artificial hip arthroplasty. Surgery to preserve the femoral head includes medullary core decompression, bone grafting, and osteotomy, and is indicated for patients with ONFH in ARCO stages I, II, and early stage III, with a necrosis volume of 15% or more. If the method is appropriate, artificial joint replacement can be avoided or postponed. Third, some exercise health care methods recommended: 1, prone leg lift method: supine, lift the affected leg, bend the hip and knee 90 °, the action repeated. 200 times a day, in 3 to 4 sessions. Suitable for: ONFH conservative treatment and surgical treatment after bed rest period. 2.Sitting position: sit on a chair, hands on knees, feet shoulder-width apart, left leg to the left, right leg to the right while fully abducted and adducted. 300 times daily, in 3 to 4 times. Applicable to: ONFH conservative treatment and surgical treatment after partial weight-bearing period. 3.Standing leg lift method: hold the fixed object, keep the body upright, lift the affected leg, make the body and thigh at right angles, bend the hip and knee 90°, the action is repeated. 300 times a day, in 3 to 4 times. Applicable to: ONFH conservative treatment and post-surgical treatment can be part of the weight-bearing period. 4, hold the squatting method: hold the fixed object, the body upright, feet shoulder width, squatting and then stand up, the action repeated. 300 times a day, in 3 to 4 times. Applicable to: ONFH conservative treatment and surgical treatment can be fully weight-bearing period. 5, internal rotation and abduction method: hand holding a fixed object, the legs are doing full internal rotation, abduction, circle movement. 300 times a day, divided into 3 to 4. Applicable to: ONFH conservative treatment and surgical treatment can be fully weight-bearing period. Walking with crutches or cycling exercises. Suitable for: ONFH conservative treatment and post-surgical treatment can be fully weight-bearing period. Femoral head necrosis has always been a problem in the global medical community, especially since the introduction of hormones and their widespread use, the incidence has been increasing year by year. Femoral head necrosis is mostly caused by hormones, alcoholism and trauma, manifesting as inflammation, edema, exudation, ischemia and necrosis of the femoral head, mainly manifesting as hip pain and limitation of movement, which can also lead to disability if not treated in time. The most effective treatment is hip arthroplasty, and there is no effective conservative treatment so far. In recent years, a team led by Dr. Jianxiong An of the Pain Medicine Center of the Aviation General Hospital of China Medical University has taken a unique approach to treat femoral head necrosis with triple oxygen therapy. Using the modern concept of “precision medicine”, the minimally invasive interventional treatment of femoral head necrosis under the guidance of imaging technology has achieved miraculous results, and has proved that femoral head necrosis can be cured at an early stage, bringing new hope for conservative treatment of femoral head necrosis. Modern medical research shows that, excluding trauma and other non-human factors, the causes of femoral head necrosis are mainly due to hormones and alcoholism, while alcoholism and smoking are important factors that cause the deterioration of femoral head necrosis in the general population. If you have been diagnosed with femoral head necrosis, quit smoking and drinking as early as possible, protect your femoral head, detect and treat it early, and choose the right treatment, you may really be able to mend the fold and return your health.
