Sorry to hear about your accident BUT glad you are alright! Everything else is replaceable accept you.
As far as a pelvic implant goes maybe one of the GFX'rs can design one for you..What color do you want it?
Just joking as to take your mind off the pain.
Did they x-ray it and find any breaks or chips in the pelvic area?
If not just try to rest and take pain meds as prescribed and only when you can't stand it any longer.
Here's hoping for a quick recovery!
