In response to your question, my 53 year old sister was diagnosed with necrosis of the left hip. Basically, the joint had slowly “disappeared” over many years of her alcoholism which is a contributing factor to some necrosis ailments.
She eventually moved in with me and I helped her lose the weight and take control of her addiction in order to qualify her for hip replacement.
The surgery and recovery went well, until she moved back home and started smoking again, which caused her wound area to open up. Over the next year, she gained the weight back and was put back on oxygen.
In 2020, my sister passed away from Covid. She was 56.
Smoking and major surgery are a no-no. Hope this helps someone!
