What does core decompression for avascular necrosis mean?

A surgical treatment called core decompression is performed to treat hip avascular necrosis (AVN). A decreased blood supply to the hip characterises a disorder known as avascular necrosis (AVN) to the head of the femur, which causes the bone tissue to die and the bone structure to collapse. The pressure inside the bone is released by performing a core decompression, and the procedure also encourages the creation of new blood vessels to aid in the healing process.

How does Dr van Niekerk perform core decompression for avascular necrosis of the hip?

In order to treat hip avascular necrosis (AVN), core decompression surgery is frequently carried out under spinal or general anaesthesia. You will lie flat on your back on the surgical table while the surgical site is cleaned and prepared. In order to access the femoral head, Dr van Niekerk cuts a small hole in the skin over the hip joint. He then drills one or more tiny holes in the neck of the femur and into the femoral head using specialised surgical equipment. The pores enable the bone to decompress, and as a result, the pressure inside the bone tissue decreases. In addition, the perforations make it possible for new blood vessels to grow into the damaged area, aiding in the healing process and restoring blood flow to the bone. In order to further relieve pressure, Dr van Niekerk may occasionally remove a small portion of the bone core that remains inside the femoral head. After the incision is closed and the decompression procedure is complete, you will be brought to the recovery area to resume postoperative care.

What does recovery for core decompression for AVN entail?

In order to heal completely following core decompression for hip avascular necrosis (AVN), recovery usually takes many weeks of rehabilitation and aftercare. The time the patient has to spend in the hospital after the procedure depends on their circumstances. Therefore, you will be observed for pain, and Dr van Niekerk will check for any other issues during this time. After leaving the hospital, you will need to restrict physical activity for a few weeks, especially weight-bearing activities. During this time, a walker or crutches may be required to help with mobility. Medication can be used to treat pain and discomfort following surgery. Dr van Niekerk will advise on when and how to take these medications. A physical therapist may be recommended to help you restore strength and movement in the injured hip. The physical therapist will provide exercises to help improve the range of motion of the hip and muscle strength. It will be required to schedule follow-up appointments to check on your recovery and track the progress of the healing process. In some circumstances, modifying one’s way of living may be essential to prevent further damage to the hip.


How long does core decompression for AVN take?

The procedure typically takes about 1-2 hours for Dr van Niekerk to complete.

How long does recovery from core decompression take?

It can take several months to recover fully, but it may also take over a year to heal for some patients.

Is there a chance of AVN recurring after core decompression?

The AVN may return if the underlying cause is not treated or you keep partaking in high-risk activities that strain the injured hip joint.
