The key to femoral head necrosis is ischemic necrosis of the femoral head and brain. Then, what are the causes of ischemic necrosis of the femoral head and brain? Doctors introduce that ischemic necrosis of the femoral head and brain is a continuous development and change pathological process. If not treated promptly, the injury may be very serious, and there is a risk of paralysis. What are the causes of ischemic necrosis of the femoral head and brain?

The causes of femoral head necrosis are various and complex, and cannot be fully classified systematically. Below, I will introduce several common causes for you.

1. Ethanol

According to the new statistical analysis of clinical medicine of bone and joint diseases, in recent years, the number of middle-aged and elderly patients with femoral head necrosis caused by alcohol is increasing, accounting for 60% of the diagnosed cases of femoral head necrosis, among whom 60% to 70% are caused by alcohol, and there is a significant trend of youthfulization; nearly 80% of the patients are about 40 years old, most of whom are unit leaders, sales personnel, and other socializing groups.

One of the serious consequences of alcoholism is ischemic necrosis of the femoral head and brain, which may even cause disability of the lower limb. In the early stage of femoral head necrosis, there may be no clinical manifestations, and the early clinical symptoms are only one side (or both sides) of the hip bone with pain. As the condition develops, hip pain intensifies, and limping appears. Experts suggest that people who socialize and drink should control their intake.

2. Cold-dampness

Patients with femoral head necrosis caused by cold-dampness are about 20% to 30%, as the body itself and the external geographical environment are balanced. Factors such as fever, cold, deficiency of liver and kidney, malnutrition of bones, and decalcification and osteoporosis can cause disharmony of Yin and Yang,侵蚀骨骼 by cold-dampness, causing meridian obstruction, belt channel blockage, leading to ischemic necrosis of the femoral head and brain.

3. Trauma

About 20% of patients with femoral head necrosis are caused by trauma, such as: femoral neck fracture, sprain, fall injury, hip joint dislocation, and acetabular dysplasia may cause vascular injury, leading to lack of water and nutrients in the femoral head, resulting in necrosis.

4. Hormonal agents

About 10% of patients with femoral head necrosis are caused by growth hormone and anti-inflammatory analgesics. Long-term use of growth hormone (such as dexamethasone, prednisone, etc.) can lead to osteoporosis, degenerative changes in bones, and vascular blockage, which slowly cause necrosis of bone cells and bone marrow cells.

5. Comprehensive factors

About 40% of patients with femoral head necrosis caused by comprehensive factors, such as a long-term alcoholic person, may experience bone hyperplasia failure, vascular injury, imbalance of physical quality and external natural environment after drinking, feeling lumbar and leg pain after drinking, which may be misdiagnosed as lumbar disc protrusion, sciatica, or rheumatism. Many long-term internal administration of growth hormone or anti-inflammatory analgesics may exacerbate the condition.
