What causes femoral head lesions?

Femoral head disease, the full name of aseptic necrosis of the femoral head or avascular necrosis of the femoral head, is a type of osteonecrosis. Osteonecrosis is the damage of osteotrophic blood vessels caused by various causes, which further leads to ischemia, degeneration and necrosis of bone. Necrosis of the femoral head is also a pathological change caused by the poor local blood supply to the femoral head due to various reasons, resulting in further ischemia, necrosis, trabecular fracture and collapse of the femoral head.

The ** of femoral head lesions may be femoral head lesions caused by femoral head necrosis, or osteophyte formation in middle-aged and elderly people, so it is a femoral head lesion caused by hip osteoarthritis, and the pain will be aggravated after weight bearing and the pain will be reduced after rest.

Necrosis of the femoral head is a very serious orthopedic disease in patients. If the condition is severe, it will affect the patient's daily life and health, and bring a lot of inconvenience to the patient's movement. Therefore, it is necessary to take reasonable ** measures against the disease as soon as possible.

The main causes of necrosis of the femoral head should also be understood, and symptomatic measures should be taken to prevent the disease from worsening. Long-term drinking will also cause more damage to our body, especially the necrosis of the femoral head in your class is also very common, mainly because the patient's blood circulation becomes slower, resulting in a lack of effective blood in the femoral head**, and long-term accumulation will lead to necrosis of the femoral head. Trauma is also a major cause of femoral head necrosis, such as femoral neck fracture, hip dislocation, hip sprain, etc.

Caused by external impact. These injuries can cause blood vessels in the femoral head to rupture and twist. In this case, necrosis of the femoral head occurs.

In the process, especially in many diseases, hormone drugs will be used, such as diseases or diseases. The abuse of hormone drugs will also cause damage to our bones, especially after the disease of necrosis of the femoral head, our physical condition will get worse and worse, and we also need to take serious measures not to use drugs indiscriminately, otherwise our condition will not be effectively controlled.

It is caused by diet, work and rest, physical reasons, work reasons and mental reasons. So when we have this situation, we must go to the hospital for a physical examination, and don't let the condition worsen.

It may be affected by hormones, it may be long-term drinking, it may be infected by a virus, it may be inflamed, it may be a weakened immunity.

Because the elderly have osteoporosis problems, their physical health declines dramatically, so it can lead to femoral head lesions.

There are many causes of necrosis of the femoral head, but the pathogenesis is still not fully understood, and there are two mainstream theories:

fat embolism theory;

Intraosseous vascular damage and intraosseous hypertension.

However, disruption of the blood supply to the femoral head is recognized as the most important pathological basis for necrosis of the femoral head.

The fat embolism theory believes that the initial cause of osteonecrosis is due to the fat embolus infarcting in the intraosseous blood vessels, and local thrombus formation, which further causes bone marrow necrosis, bone hypoxia, and bone cell death. The theory of intraosseous vascular damage and intraosseous hypertension suggests that osteonecrosis resembles a fascial septal syndrome, mainly caused by increased pressure outside the intraosseous blood vessels.

The femoral head is a common term that actually refers to the area of the hip joint, which mainly includes the femoral head, the contralateral hip joint, the acetabulum, and the ligaments, cartilage, muscles, tendons, and other tissues around the hip joint. Therefore, the femoral head pain we often talk about may be caused by necrosis of the femoral head, strain of the hip joint, dysplasia of the hip joint, hip arthritic disease, hip tumor disease, cartilage, fish lip, ligament, tendon injury, etc. Diseases of the lumbar spine may also spread to the hip or hip joints, which can also cause local discomfort.

1.Hormonal drugs. Long-term use of a large amount of adrenocorticosteroids can cause osteoporosis, arterial vascular blockage, and gradual necrosis of bone cells and bone marrow cells.

2.Rheumatism. Half of them occur in cold and humid climates, which are common in China, less in South China, and gradually increase in the north, often combined with ankylosing spondylitis and rheumatoid arthritis.

3.Osteoporosis. Due to the change of the internal structure of the bone tissue, the trabecular bone is partially damaged, and the blood circulation of the bone is blocked, which is easy to cause necrosis of the femoral head.

4.Chronic alcoholism. Alcoholism can cause abnormal lipid metabolism, and clinical data confirm that the necrosis rate of femoral head is significantly increased in long-term heavy drinkers.

5.Liver and kidney deficiency. Most of them are age-related, and they are also related to liver and kidney deficiency caused by previous internal or surgical diseases.

6.Bone tuberculosis. Due to the erosion of bone tissue by Mycobacterium tuberculosis, cystic changes occur in the acetabulum and femoral head, and the femoral head is prone to mushroom-like changes, collapse, functional deficits, and necrosis of the femoral head.

7.Osteodystrophy. Due to long-term poor diet, the intake of calcium, phosphorus and jujube in the body is insufficient, which can not meet the metabolism, growth and development of bone tissue, etc., which can easily lead to obstruction of circulation, and necrosis of the femoral head due to insufficient blood supply.

8.Trauma. Trauma is also the cause of femoral head necrosis, femoral neck fractures, sprains, falls, hip dislocations, acetabular hypoplasia are prone to femoral head necrosis, the incidence is generally 75%, and most of them can occur osteonecrosis after fracture surgery.

There are no obvious symptoms in the early stage of femoral head necrosis, and there may be soreness and discomfort in the hip joint, mostly after standing for a long time, or walking a lot. If you have such symptoms, you can do a hip X-ray, or an MRI of the hip to see if there is femoral head ischemia.

Hello, the main pathology of femoral head necrosis is the obstruction of blood circulation of the femoral head and the destruction of the head bone ischemia, so it is mostly called avascular necrosis of the femoral head or aseptic necrosis of the femoral head. Therefore, we must pay attention to the blood vascularity when we are in the first place, so that we can get an effective one. Simple drug ** is useless, because its own blood supply is not very abundant, so the drug can not directly reach the necrosis site to play a **role, which will only aggravate necrosis and delay **the best time**femoral head necrosis can not be just a simple drug** requires a variety of methods to combine** drug is only an auxiliary in the later stage**.

The most common symptom of necrosis of the femoral head is pain, which can radiate to the knee in the hip joint, proximal thigh, and radiating to the knee. Pain can be caused by necrotic tissue-repaired inflammatory lesions or high pressure within inflammatory lesions, and can manifest as persistent, resting pain. Osteochondral collapse and deformity leading to traumatic arthritis, or chronic traumatic pain at the musculoligament attachment site around the hip joint.

Hip mobility is limited, particularly rotational motion, or painful and shortened claudication. In the case of necrosis of the femoral head, blood-invigorating and bone-strengthening drugs should be used promptly**.

Hello, there are many causes of this disease, which may be caused by prolonged sedentary or excessive labor.
