I've been diagnosed with Avascular necrosis again. I've had a total hip replacement on the right. I now have it on the left. My my current surgeon doesn't believe replacement will help.She says I also have arthritis and the bone is only "slightly" collapsed. I've had 2 fluoroscopic injections on my lt. hip the 2nd on 12/24 I can't bear any weight.This has gone on for 6 months.
