The only thing I could find was about the corticosteroid use as well. I am so sorry that you are suffering with that. It is sad that when you needed an MRI "it wasn't time yet". I can't believe that the insurance companies get to control the doctors in telling them how to treat their patients, but I am holding my tongue. I mean, how dare you want an MRI to see changes in something like that.

Necrosis can be caused from insufficient blood supply to the joint. Has anyone checked that?

Sorry, that is one thing I have not heard of but it sounds like some RA symptoms. I had a knee replacement 2 years ago because of RA. Got infected and 3 more surgeries. Still a lot of pain due to scar tissue intermingling with my nerves.

I am now having a lot of pain in my left shoulder and I had a cortisone shot 3 months ago but it has worn off. Who knows if there is a difference between the two?? I can see where they can get misdiagnosed!

Praying for you Laura!!!! 💕🙏🏼💕🙏🏼💕

Most hip replacements go very well. As RN I specialized in hip and knee replacements, at home recovery for years. They are easier than knees because there is less motion in a hip. a knee can do 180 degrees, hips are more limited. Necrosis is a very rare thing, and they don't really know the cause. I would definately check on a surgeons success rate. There are some bad seeds , as in any profession, Best of luck , so sorry you suffered so long, your pain must have been excruciating. p.s. xray would have shown the missing hip head and then insurance would have allowed MRI. Insurance excuses are bull shit.
