Thank you for the warm welcome. Very happy to be part of the community.
My mother had liver failure which caused avn in both of her hips. They are completely gone and they cannot see any bone on the xray. She was in a lot of pain until her liver transplant and could only walk a few steps with a walker.
Since the transplant she does not have pain (the new liver helped rebuild strength), walks 90 steps a day with walker and can free-stand for 15 seconds at a time without buckling.
She wants to walk again and has a dr willing to do reconstructive surgery, however i am worried about doing it due to infection after surgery. It would be hard to clear because she is on immunosuppressant due to the transplant.
Lastly, The bone is in soft tissue of some kind, dr’s have no idea what, and have no idea how she is walking.

My questions is, could it be possible to walk and put all her body weight on a leg without a hip?
As she doesn't have pain now, could it be a question of strengthening the leg muscles and she could walk (with cain/do stairs) or would walking without hip joints make her very unstable and be dangerous?
If anyone has any idea who could answer this, please send me the reference. Thank you!!!
