question: Hello doctor, I am a 66 year old female with RA. Some years ago (about 13years ago) one of the options suggested to me was fusion. My new doctor has stated that I am a good candidate for wrist replacement. How long has this new procedure been used and is it safe? Will the whole wrist be replace? I want to know as much as possible before making a final decision. What are the replacement parts made of? Will I feel them moving and will I still have flexibility in my wrist and fingers still?
