How do you change an obese patient if her legs are painful and left hip bone has despised?

If you mean "displaced" hip, that is considered a medical emergency, you need to call 911 and get this person to the ER.

My husband displaced his hip (he had total hip replacement 1999-2000) in 2015; actually, he did it twice and both times it was a trip to the ER. While they were displaced, he had absolutely no range of motion; he had to be immobilized on the trip in the ambulance, otherwise there might have been some serious damage done.

If there is indeed a hip displacement, changing this person is the least of your concerns right now.

"Displaced" perhaps?

I can make out that you mean an obese patient, but I can't understand a "despised hipbone". I am afraid it is almost impossible for one person to change an obese person who has no control over body. If this is a broken hip it is even more impossible. You may need to consider skilled nursing facility. I am afraid that like most of us nurses you will end with a bad back.

I assume you mean you are trying to change an obese patient, but what does a 'left hip bone has despised' mean? If a patient is obese and has painful legs, changing her diet to a healthy one where she can lose weight would certainly help. If she is confined to a bed, who's bringing her all the food?

Are you asking how to change her adult brief while she's in bed or what, exactly?

You need to clarify your question, add details and discuss what you mean re: her left hip bone before you can get any helpful answers.
