Avascular necrosis of the head of femur is usually detected clinically by:
a) 3 months
b) 6 months
c) 11months
d) 15 months.
The femoral necrosis is a disease caused by the death of the femoral femur due to the lack of blood ischemia of the femoral femoral bone (also known as vascular necrosis or blood ischemia of femoral femoral necrosis or femoral necrosis).
In the loss or lack of blood ischemia of the femoral head results in death of the bone and lead to the breakdown and breakdown of the structural shape of the bone.
This lack of blood perfusion may be due to many known causes, some unknown, and may occur at all ages, but it is common in the ages of 30 to 60 years.
Causes and symptoms
The necrosis of the femoral head may occur for known reasons such as:
- Injury or fracture of the femoral femur:
Injuries, fractures or dislocations in the hip joint may cause damage to the blood vessels feeding the femoral femur.
And in some cases of cancer treatment involving radiation therapy, as radiation may cause bone weakness and damage to blood vessels feeding the bone.
- fatty deposits in blood vessels:
The fat deposited in the blood vessels may impede blood flow to the microvascular, resulting in a lack of blood perfusion.
- Some systemic and immunological diseases:
Some diseases such as hemophilia, sickle cell anemia or Gaucher disease, which cause a lack of blood perfusion of the bone.
- Steroid abuse:
High and excessive doses of steroids may cause necrosis of the femoral head. Although the exact cause is unknown, some scientific studies suggest that excessive doses of steroids lead to increased accumulation of lipids in the blood vessels, leading to a decrease in blood perfusion of the femoral femur .
- Alcohol:
Excessive use of alcohol leads to fat deposits in the blood vessels leading to a lack of blood perfusion of the femoral femur.
Many patients may not have any symptoms in early cases.
When the condition begins to worsen, the patient may experience pain only when an effort is made or some weight is placed on the damaged joint.
When the condition is advanced, the patient may experience constant pain even at rest.
The pain is usually concentrated in the upper thigh area and the hip side and the mechanism, and many cases occur in the ischemia of the sides (ie the articular hips).
When the patient's hip head develops, the hip joint becomes rough as a secondary disease caused by the death of the femoral head.
