What is the avascular necrosis of the femoral head?
femoral head is a femur -shaped ball or femur. It fits in a hip -shaped cavity, known as acetabul, and both parts form a hip joint. Avascular necrosis of the femoral head is a condition in which blood supply to the femoral head is lost, leading to osteonecrosis or bone cell death. The causes of the condition may include steroids and other medicines, alcoholism and accidental injuries. While medicines and combinations of resting and stretching exercises can help with symptoms, surgical treatment is usually required to effectively treat the condition.
The blood is supplied to the femoral head with arteries that move along the femoral neck, a narrow part of the bone connecting the femoral head connecting femur. Because it is the only blood supply, if the flow is disrupted, the bones of the femoral head can die and its rounded structure can collapse and level. Once the hip joint is no longer smoothly together, the joint surfaces can be worn and the joint deterioration can be adjusted.
Avascular necrosis of the femoral head usually leads to pain that occurs when weight is placed on the hip. Most often the pain is felt in the groin, but can also be felt in the buttocks or thighs. If necrosis of the femoral head progresses, hip pain may occur, even if the person rests, and can be difficult to walk, with stiffness and limping over time. Femoral neck fractures can cause avascular necrosis as well as hip dislocations. Conditions such as alcoholism and diabetes may damage the blood supply to the femoral head as they can take steroids at high doses or for a long time.
If the avascular necrosis of the femoral head did not advance too far and the femur's head has not threatened, the most common treatment is the surgery called the core of the decompression. During the Decompression Operation core, the surgeon drills a femoral neck and creates channels through which new blood vessels can grow andCreate blood supply for the head. The procedure can be carried out by minimally invasive techniques, often known as a keyhole surgery, and does not require a hospital stay.
core decompression usually prevents progression and relieves any pain due to avascular necrosis of femoral head. In cases where the condition proceeded and the hip joint has deteriorated, arthritis usually evolves. Then the recommended treatment is the removal of the femoral head and neck, along with the acetabul and instead inserts an artificial side. This operation is known as the overall hip replacement.
