Members' feedback

"I'm finding it shocking and surprising the number of new people joining the community. Let me explain. I was diagnosed with AVN first in both knees back in 2005, over the next few years it was found in both hips and shoulders. I had never come across AVN before and felt like I was the only person with it, I was always having to explain to people what it was."
"Thankfully I found this website and community over a year ago and realised I was not the only one suffering with AVN, it has been such a help talking to fellow sufferers who understand what I am going through."

Welcome to Avascular Necrosis AVN Charity UKHealthy BonesHealthy Bones

Charitable trust dedicated to spreading the awareness, understanding, support and needed research into the rare bone condition of Avascular Necrosis (AVN). The disease is also known as Osteonecrosis (ON), Ischemic bone necrosis, Bone Infarct and Aseptic necrosis.

In children it is known as Perthes disease. When triggered by radiotherapy it can be known as Osteoradionecrosis ORN. We generally refer to it as AVN. When occurring in the knee, it may be known as SPONK and when in the jaw it may be known as BRONJ.

There are no statistics available but we believe there are between 750 and 2,000 new cases of AVN diagnosed each year in the British Isles.

We are the only UK and Ireland organisation dedicated to AVN. We are very new - created by a couple of fellow sufferers, with the objective of offering information and support in different ways to anyone in the British Isles who has, or is in any way affected by this condition. Also to promote the much-needed research into Avascular Necrosis AVN.

Definition of Avascular Necrosis AVN

Avascular - Having few or no blood vessels*

Necrosis - Death of living tissue*
* From Encyclopaedia Britannica

The bones in the joint having been deprived of a good blood supply, result in the death of the bone. In time this concludes with partial or complete collapse of the affected joint.

It is a disabling condition affecting any joint in the body with no known cure. It can affect a single joint, many different joints (multi focal), or both left and right of the same joint (bilateral).

The disease affects young and old alike with resulting continuous chronic pain that some say is comparable with bone cancer.

Avascular Necrosis AVN is not classed as hereditary, but some of the causes may be.

While disabling, thankfully AVN is not life threatening. Unfortunately it is often progressive, meaning it worsens with time, so managing AVN can be a lifelong process.

Understanding the pain from AVN

Click image for more info.Feedback from almost all AVN sufferers in our community has revealed that our health service specialists have little or no understanding of the horrific pain that accompanies AVN. The x-rays and MRI scans do help the specialist understand what has happened within the affected joint / bone, but these images do not convey the chronic pain and devastating effect this has on the quality of life.

This is one of the biggest frustrations for all AVN sufferers.

Awareness of AVN in the British Isles

Very few people have heard of Avascular Necrosis AVN Osteonecrosis. Except for the medical profession, it is probable that only sufferers and those close to them have any awareness of the disease.

Sadly when first getting diagnosed it can be a very lonely place, full of frustration, despair and complete loss of hope.

Our charitable trust addresses these frustrations by opening doors of knowledge and shared experiences to sufferers and those around them.  By definition, sharing is helping.
