Avascular necrosis (AVN) is a decay and collapse of cartilage that occurs as a result of the inability of the femur, that is, the head part of the hip bone (the round part) to feed on blood vessels.

The first symptoms are pain, pain and movement restrictions that occur during walking and loading.

In the advanced stages, there is a loss of strength and limping in the hip.

AVN has 4 stages; Grade 1, 2, 3, 4.

1 and 2. At the stage, when the patient only complains of pain, there is no serious cartilage deterioration detected on MRI.

3 and 4. At the same time, complaints may have increased. We watch for cartilage distortions that are serious enough to be seen on an X-ray.


  • Accidents and serious traumas
  • Wrong surgeries
  • Excessive alcohol consumption
  • Long-term use of cortisone


** Treatment of Avascular Hip Necrosis (AVN) with Resuscitation Surgery **

In the early stages (1. and 2. Stage) methods that will ensure more nutrition of the femoral head, whose nutrition with blood vessels is impaired, are targeted.

In resuscitation surgeries, new surgical techniques are used to promote the healing of the femoral head, allowing healing blood cells and stem cells produced by the body to migrate to this area.

Externally injected treatment approaches, such as PRP and Stem Cell injection, do not have a proven effect.

3. As a more radical method at the stage; it is the transplantation of the fibula bone along with the fibula vein taken from another part of the body to the area with AVN in the hip. This method provides benefits in about 50% of cases, but it is a heavy operation in terms of the healing process.

4. At this stage, prosthetic surgery is required.

** Treatment of Avascular Hip Necrosis (AVN) with prosthetic surgery **

The parts damaged due to AVN are removed and an artificial hip joint is placed in its place. Thus, the hip replacement completely replaces the damaged joint and the patient’s complaints pass by 98%.
