In order to deliver the cells that are responsible there needs to be adequate blood flow. If the blood flow is disrupted significantly, the affected areas can undergo avascular necrosis (avn). Avn can lead to collapse of the area and arthritis if it occurs near joints. ...Read more

What should I do about avascular necrosis?

What should I do about avascular necrosis?

AVN: More information needed. In some bones (humeral + femoral head) if diagnosed before collapse and arthritis begins, there may be some value to core decompression.

Once collapse occurs, some sort of resurfacing/replacement required to manage pain. ...Read more
