How is femoral head necrosis caused? The bane may be these 3, don't take it lightly

The femoral head, which is located in the human hip joint, is like a portal shaft that bears the entire weight of the body. If something goes wrong, it will be a real "general discomfort", which Mr. Chen has a deep understanding of. A few months ago, Mr. Chen often felt sore hips. He had to sit down halfway through his walk, and he could not sit on a chair that was too low, otherwise the pain would worsen. Some time ago, Mr. Chen's hip joint became more and more painful. Sometimes he would wake up in the middle of the night with pain. Later, it was difficult to even squat down. On this day, he took advantage of the company's holiday and went to the hospital alone to see a doctor. After a careful examination, the doctor diagnosed Mr. Chen with avascular necrosis of the femoral head, accompanied by arthritis of the hip.

First, femoral head necrosis, these three factors cannot be ignored

Femoral head necrosis is caused by a variety of factors, but There are three main high-risk factors for femoral head necrosis: 1. Excessive drinking will not only cause liver fat metabolism disorder, but also increase blood lipids, resulting in higher blood viscosity and slower blood flow , thereby causing blood coagulation, resulting in insufficient blood supply to the bones, and finally causing avascular necrosis of the femoral head. 2. Hormones Generally speaking, excessive hormones may lead to hormone-induced necrosis of the femoral head. The specific etiology is still unclear, mainly due to the effect of hormones, leading to problems such as blood hypercoagulation, vascular occlusion, and osteoporosis. 3. The phenomenon of avascular necrosis of the femoral head caused by trauma is common in adolescents, because the degree of violence of femoral neck fractures in adolescents is greater than that in the elderly, and it is usually accompanied by obvious fracture dislocation and local vascular damage. In addition, factors such as the quality and time of fracture reduction and internal fixation also affect the necrosis rate of the femoral head.

Secondly, these three symptoms may be a "precursor" of femoral head necrosis

The femoral head is an important part of the left and right hip joints. It is located in the pelvis. The lower part and the root of the thigh have the function of connecting the previous and the next. Once the blood supply to the femoral head is disturbed or destroyed, it may cause bone tissue damage. If there are structural changes, collapse and deformation of the femoral head, joint inflammation, dysfunction, etc., it may cause femoral head necrosis. Femoral head necrosis, there are usually three abnormal manifestations: 1. Pain The first symptom of bone necrosis is pain. The pain is mainly in the crotch, buttocks and thigh root. The early pain is mainly during weight-bearing. If the patient does not With weight bearing, the pain is not noticeable. However, the pain can worsen as the condition progresses, causing discomfort in the hip joint. 2. After the femoral head necrosis of the movement disorder, it cannot be as flexible as before. Therefore, some patients will have symptoms of hip joint mobility disorders such as being unable to squat, cross-legged, and cross-legged. 3. Skeletal deformation Once the necrosis of the femoral head develops to a certain extent, it may lead to the collapse of the femoral head, resulting in shortening of the affected limb, pelvic tilt and other symptoms. The above symptoms are all manifestations of femoral head necrosis, but this manifestation is not very specific. To confirm whether there is femoral head necrosis, further mirror examinations, such as magnetic resonance examinations, are required. Diagnosed.

Third, don't want femoral head necrosis, pay attention to these 3 points

In fact, the root cause of femoral head necrosis is still unclear. However, clinical data show that femoral head necrosis is related to alcohol abuse, hormones and other factors. Therefore, controlling these high-risk factors can play a preventive role in femoral head necrosis. (1) In daily life, increase calcium intake, eat more fresh vegetables and fruits, get more sun exposure, and exercise regularly every week. (2) Before exercising, you should fully prepare your hips, and do not exercise until you feel your body is slightly warm and your limbs are stretched out. (3) When carrying heavy objects, pay attention to avoid spraining the hip, and try not to do too heavy work.
