Hi
Welcome to Hip Talk.
Have you talked with any of the really experinced hip resurfacing surgeons yet? Some will do people that are overweight. I know Dr. De Smet of Belgium will. It is a question you need to ask of the surgeons. I would stick with the really experinced surgeons that have done a thousand or more. They are much more likely to do difficult cases.
It sounds like you have done a great job to lose 90 pounds. That is a lot of hard work and dedication. Please keep positive and keep working on getting your hip/s fixed so you can continue to become active again.
I don't have the exact BMI that are limits, each surgeon looks at each person as an individual case. Some of the surgeons will give you a free consultation via email if you send them your story and attach your x-rays in a digital format as a .jpg Dr. De Smet of Belgium, Dr. Bose of India, Dr. Gross of SC, Dr. Mont of MD and Dr. Rogerson of WI are among the few you can email and get a free consultation. Tell them your situation and I know the will talk with you. Here is my list for the surgeons contact information
