What is the cause of avascular necrosis of the femoral head

summary

Grandfather Zhang always feels bone pain recently. He is very uncomfortable and can't do anything. After seeing it, the doctor said it's avascular necrosis of the femoral head. It's said that the causes are various. Next, let me talk about the causes of avascular necrosis of the femoral head.

What is the cause of avascular necrosis of the femoral head

First, trauma leads to necrosis of the femoral head. Such as femoral neck fracture, hip joint dislocation, hip joint sprain and contusion caused by external force impact. Trauma is the main cause of femoral head necrosis. However, the occurrence and extent of traumatic avascular necrosis of the femoral head mainly depend on the degree of vascular destruction and the compensatory ability of collateral circulation.

Second: drugs lead to necrosis of the femoral head. For example, because of tracheitis, asthma, rheumatism, rheumatoid arthritis, neck and shoulder pain, diabetes, skin diseases, and long-term use of hormone drugs. Due to the large or long-term use of hormones, resulting in the accumulation of hormones in the body and the disease, this is an early statement. Recently, it is considered that the occurrence of femoral head necrosis is directly related to the type, dosage form and route of administration of hormone, but not directly proportional to the total amount and time of hormone. However, long-term use of a large number of hormones or excessive daily dose, dose change mutation is also one of the causes of femoral head necrosis.

Third: alcohol stimulation leads to necrosis of the femoral head. The accumulation of alcohol in the body caused by long-term and large amount of drinking leads to the increase of blood lipid and the damage of liver function. The increase of blood lipid results in the increase of blood viscosity, the slow down of blood flow, the change of blood coagulation, which can cause blood vessel blockage, bleeding or fat embolism, resulting in bone necrosis. The clinical manifestations were aggravated after drinking, walking duck step, heart failure, fatigue, abdominal pain, nausea and vomiting.

matters needing attention

There are many reasons for avascular necrosis of the femoral head. The above introduces three common factors. In this case, it is suggested to go to the hospital for a specific examination, and then see how to treat it under the doctor's advice.
