ExJock,
Don't know if it's too late, but have you obtained a copy of your surgical report from the hospital records? I was able to get one around 4 months out and kept it for my records. It contains everything that was done during surgery. To get this, just contact hospital records and request a copy, then go in and sign the release form. Pretty simple really and it will answer all your original questions. Also handy to have for second opinion if necessary. I just like to be informed on what was done and keep in my files for future reference.
Hope you are feeling better soon!
