What causes necrosis of the femoral head?

Causes of necrosis of the femoral head

Mainly we are talking about inducements, and there are several main types of inducementsOne is hormonal, taking hormones in large quantitiesBecause of other diseases, this can cause necrosis of the femoral head.

The other category is alcoholism, that is, drinking a large amount of liquor for a long time, drinking liquor, can cause necrosis of the femoral head. Other rare causes, such as aviation sickness, diving sickness, or other rare causes, can also cause necrosis of the femoral head, which is precipitating.

Why does necrosis occur?

with the femoral headCharacteristics of blood vesselsThere is a certain relationship, and the blood circulation of the femoral head is mainly thereThree branches, one branch is the medial circumflex femoral artery, which is the main ** proximal femoral head and the area of the weight-bearing area of the blood vessels. The lateral circumflex femoral artery is primarily responsible for the area of the distal non-weight-bearing area below the femoral head. There is also a small fovea artery at a young age, which is mainly distributed in some areas around the head depression of the femoral head, some areas, ** blood circulation in this area.

In adulthood, the foveolas artery slowlyIt's occluded, the main ones are the medial circumflex femoral artery and the lateral circumflex femoral artery**femoral head. Avascular necrosis of the femoral head is mainly caused by the blockage of some capillaries in the medial circumflex femoral artery into the femoral head. Most of these blockages are due to alcohol consumption, taking hormones or some other diseases, resulting in the enlargement of fat cells in the femoral head, the increase of fat particles, and the formation of capillary blockage, and then the formation of a type of disease called avascular necrosis of the femoral head.

The main reason is that the blood circulation in the femoral head is blocked, and this obstruction may also come from outside the blood vessels, such as the increase of fat cells between the capillaries, the increase of fat particles, or the increase of fat particles from the inside of the blood vessels, which will block the capillaries, which will cause unobstructed blood flow, resulting in the blood of the bone tissue and connective tissue in the femoral head is not smooth, which will cause apoptosis of cells, mainly bone cells.

After apoptosis, this kind of trabeculae will slowly disappear, and the bone pit will appear hollow, and then the trabecular bone will be broken, and then there will be some fractures, which will accumulate for a long time, and after the trabeculae are lost a lot, the support of the femoral head will be greatly affected. Coupled with the fact that people walk and jump in their daily lives, it will cause the collapse of the femoral head.

When there is such a small collapse, the patient will have some obvious symptoms, which will gradually worsen, and as the collapse continues to worsen, the symptoms will become more and more severe, which is the process from the early stage to the late stage of femoral head necrosis.

The immediate cause of necrosis of the femoral head is a decrease or disruption of blood** at the femoral head.

The following factors can lead to insufficient blood in the femoral head:

Trauma. Trauma such as hip dislocation or subluxation, femoral neck fracture, etc., can interrupt the blood supply to the femoral head.

Violent impacts caused by traffic accidents can also cause disruption of blood supply to the femoral head.

Certain diseases. Sickle cell anemia.

Systemic lupus erythematosus.

Decompression sickness. Gout.

Blood clotting disorders. Chronic liver disease.

Certain medications and ** measures.

Long-term use of corticosteroids in high doses.

Radiotherapy. Chemotherapy.

Bad habits.

Alcohol abuse can cause abnormalities in blood clotting in blood vessels, leading to problems with the blood supply to the femoral head. People who drank less than 400 ml of alcohol per day had a nearly three-fold increased risk of necrosis of the femoral head compared to those who did not drink alcohol. If it is more than 400 ml, the risk is even higher.

Smoking: Smoking increases the risk of necrosis of the femoral head.

Who is susceptible to necrosis of the femoral head?

Gender: Males are more likely to be affected than females.

Age: 30 to 50 years old are most susceptible.

Pregnancy: Weight gain during pregnancy increases the weight-bearing burden on the femoral head.

Obesity: Obese patients have a higher risk of developing necrosis of the femoral head due to a greater burden on bone weight-bearing.

Femoral head necrosis is a common type of hip joint disease in clinical practice, which may cause necrosis of the femoral head for many reasons

1. Long-term heavy drinking;

2. Fracture of femoral diameter or femoral base, resulting in obstruction of blood circulation of the femoral head;

3. Long-term use of a large amount of hormones, for lesbians, many lesbians may develop immune diseases, and sometimes the incidence rate may be higher than that of gay men, resulting in necrosis of the femoral head due to hormones, which may be more common in the female population.

No matter what it is, it is the necrosis of the bone caused by ischemia in the femoral head, to put it bluntly, it may be like a rotten apple core, with the increasing severity, the femoral head may collapse, resulting in the unequal length of the lower limbs, so to judge the necrosis of the femoral head in women or lesbians, it is necessary to combine the medical history, clinical physical examination, and necessary auxiliary examinations, comprehensive analysis and judgment can clarify what the cause is, or what is the severity, and how to proceed**.

The causes of necrosis of the femoral head are as follows:

1. If the blood in the blood vessels of the femoral head is affected, it is easy to have necrosis of the femoral head, such as long-term use of hormones; or the hip joint is subjected to some external force, and the patient has a femoral neck fracture; Long-term heavy alcohol consumption, especially liquor, is a high-risk factor for femoral head necrosis;

2. Hemoglobinopathy can lead to necrosis of the femoral head;

3. Decompression sickness is common in divers, if the water pressure is high to the surface of the water with low water pressure, the blood and blood circulation in the femoral head will be affected to a certain extent. If the patient has recurrent and long-term insufficiency of femoral head supply, he or she is prone to necrosis of the femoral head. After the necrosis of the femoral head, the femoral head is deformed and collapsed, and the patient will experience pain and soreness when walking.

1. Heavy alcoholism

Some people like to drink, and for people who drink regularly, it will seriously damage our bone tissue, so for the sake of our health, we should reduce the number of times we drink, and we should drink alcohol moderately, and proper drinking is better for the body.

Second, in the case of trauma, such as a fracture

When because of an accident, our legs or feet will have some trauma, if it can not be carried out in time, then it will cause some infection or bacterial invasion, so when the trauma occurs, it should be carried out in time, and it should be disinfected and sterilized in time to prevent the deterioration of the condition.

3. If you take a large amount of hormones or drugs

If the patient eats a lot of drugs or takes a lot of hormones, it will also cause damage to our body functions, so we should not take medicine casually, can not inject randomly, and cannot randomly play hanging bottles, because these drugs contain a lot of hormones, hormones will seriously affect our body, so this phenomenon should be prevented.

In the case of femoral head necrosis, we give early prophylaxis, and the following should be noted:

1. Avoid overwork.

It is possible to avoid overexertion and not engage in some high-intensity work.

2. Reduce walking.

In order for your bones to be healthy, you should reduce the number of walks.

3. Appropriate exercise.

Proper exercise, such as swimming, can also be used to restore bones.

4. Reduce the phenomenon of jumping.

For the phenomenon of necrosis of the femoral head, the occurrence of jumping should be reduced.

5. Try to maintain bed rest.

If the bones are more serious, you should keep on bed rest, and you should keep your mood happy, you should make your mood better, you can't not pay attention to yourself because you have a disease, you should make your mood better, in order to ensure the health of the body, in order to improve the body's immunity, so that people are not easy to get sick.

Necrosis of the femoral head can be broadly divided into the following causes. Intraosseous blood vessels are damaged, resulting from intraosseous vascular hypertension. Intraosseous vascular damage can be divided into several causes of this phenomenon.

If the patient drinks alcohol for a long time, does not have good lifestyle habits, and smokes for a long time, then it is likely to change and change the health status of the body's blood vessels, which may also cause necrosis of the intraosseous blood vessels. In this way, the femoral head is in a bad state for a long time, which is likely to lead to the occurrence of necrosis of the femoral head.

In addition to long-term drinking, if a person is too obese or suffers from chronic diseases such as high blood pressureIt is likely that the blood vessels of the body will be in a state of high pressure operation, so that the pressure on the body itself is too heavy, which brings a huge workload to the bones, and because the blood vessels are not healthy, they cannot provide oxygen and blood nourishment for the bones, so at this time the necrosis of the femoral head will also occur.

Trauma is also one of the main culprits in necrosis of the femoral headWhether it is affected by the outside at work and in life, or the external pressure is too great, so that the hip bone and buttocks have been seriously damaged, at this time it will also cause the phenomenon of femoral head necrosis, so we must pay attention in daily life, do not do too heavy physical work in work and ordinary life, and you must protect your waist and hips when working, so as to avoid being harmed by trauma and causing necrosis of the femoral head.

Studies have shown that 17% of patients with necrosis of the femoral head are due to genetic causesSome people may wonder if it is a bone disease, so why is there such a thing as hereditary? In fact, the heredity here refers to some people who have a family history of heart disease and high blood pressure, as has been repeatedly said above, femoral head necrosis is inseparable from the health of blood vessels, and it is precisely because of the congenital unhealth of blood vessels brought about by heredity that some people will have the disease of femoral head necrosis.

Alcohol, hormones, and trauma are the main causes of necrosis of the femoral head. Overall, disruption of blood circulation is the root cause of necrosis of the femoral head. There is a clear record in the Yellow Emperor's internal scripture paralysis theory, wind, cold and dampness, heterozygous and cure.

In other words, wind cold and dampness are the root cause of necrosis of the femoral head.

There are many causes of femoral head necrosis, such as congenital dysplasia, long-term alcoholism, heavy use of hormones, and untreated hip injuries, so femoral head necrosis must start from the source, especially patients with bad habits such as alcoholism and smoking. At the same time, conservative drugs can be used for necrosis of the femoral head, and drugs with the effect of invigorating blood circulation and strengthening bones are a good choice.

Hello; Environment: Avascular necrosis of the femoral head can be caused by particularly poor living conditions, especially radiation damage to the human body by radiation from certain minerals. 2. Trauma:

Femoral neck fractures, pelvic fractures, traction injuries during midwifery during dystocia, soft tissue injuries around the joints in early childhood, and various traumatic injuries that are not properly handled or delayed for some reason at that time eventually lead to avascular necrosis of the femoral head. 3. Long-term excessive alcohol abuse is also one of the causes of necrosis of the femoral head.

This is still more complicated, everyone's situation is different, trauma, alcoholism, fat cell necrosis, etc. are all possible causes, which need to be analyzed by specific patients.

The most common cause of necrosis of the femoral head is due to fracture trauma or regular use of hormones, and the main clinical manifestation of this condition is hip pain.

The main early symptom of femoral head necrosis is that the hip pain may become difficult to walk over time, and MRI can usually be done early in this condition.

Hello, avascular necrosis of the femoral head is due to trauma, alcohol, hormones, congenital hip dysplasia and other causes that lead to the blockage of one or more blood vessels in the three major blood supply arteries (lateral circumflex artery, medial circumflex artery, ligament artery) located at the junction point of the upper and lower limbs of the femoral head, thereby causing bone cell ischemia and necrosis, trabecular fracture, and femoral head collapse. Bone cells are re-nourished, and elastic-guided extracorporeal shock waves are used to induce bone regeneration and restore hip joint mobility.

Hello, necrosis of the femoral head is the most common form of chronic alcoholism, such as heavy drinking. Another reason is the use of hormones in large doses.

Recommendations:1If you have a problem with alcoholism, get rid of the bad habit. 2.Reduce the use of hormones or even not. 3.Reduce weight-bearing, walking, walking on crutches, reduce pressure on the femoral head, avoid fractures, collapse.

Femoral head necrosis is mostly called avascular necrosis of the femoral head or aseptic necrosis of the femoral head because its main pathology is the obstruction of blood circulation and destruction of the femoral head. Presenting with difficulty in moving, hip pain and discomfort, it is recommended to consider joint replacement surgery to avoid further degeneration of the acetabulum, joint replacement surgery can restore the length of the lower limbs, correct the unequal length deformity, and improve the function of the lower limbs.

There is hope for surgery in your condition**. But because you're younger, you may face more than one revision surgery. Good luck soon**!
