Hi
Thanks for posting to others on the Hip Talk Group. I know they appreciate it.
Usually as far as I have learned, they take your x-rays and do actual figuring and marking on it to determine what size hip to use. It is very scientific and they try to match your normal size ball of your femur. They can't go much larger because they would not have much extra room to set the acetabular cup in your hip. I have seen marked up x-rays.
So I am guessing that he used somthing very close to your original size.
Vicky, my friend and contributor, was just at a Orth Conference with Treacy and McMinn. She sat at their table. Too bad you hadn't asked the question before she went to the conference, she could have asked for you.
This is a really technical quesiton. Maybe you should ask Mr. Treacy sometime when you write to him.
