I agree. I thought I was seeing an orthopedic dr for an osteo a hip replacement. My dr saw something on the x ray so a MRI was performed and AVN was found on top of both ball joints in my hips. I was over the usual age. There is a list of items that can cause it. I had none. Next I had core decompresions on each hip to first relieve pain and pressure. Also a hole is drilled in the bone. This is to promote bone regrowth and new blood vessels to bring more blood supply to the head. My left hip was really bad. After two yrs I needed full hip replacement. This was in 2004 and replacement on 2006.. My rt hip has held its own and has stayed unchanged. I was 61 yrs old and I am 67 now. I also have o/a and r/a as well. I also have connective tissue issues. So now I have joint and muscle, ligaments etc as well.
I don't know if this helps anyone.
