Hip is done from a partial bipolar prosthesis to a full hip revision. The ball at the top of my prosthesis was too big and it was also a partial before. So far I have less pain then I have been experiencing in the last 2 years. I take 1/2 tab of my pain killer. Strangely when I sat down after my first surgery I felt like I was sitting on a ball. The ball at the top of the prosthesis was too big so dr hedley took it off replaced it and made it a full hip. I dont feel tha ball anymore when I sit and the pain afterwards is less than the the last 2 years. Please God let it be even better after this heals. I love the docs I met with the group the hospitalists the hospital was nice too. I am so thankful that I found Dr Hedley when I did. I was so bummed about not being able to be active. Let you know how it goes.. so far so good.
