I had a fracture from the outer edge of my right ilium clear through to the sacrum from a bike wreck in '05 (also 2 pubis fractures like yours). I had surgery for the ilial fracture with a plate and four pins to keep everything together. I was totally non-weight bearing (per surgeon's orders) on the right side for eight weeks. Used a walker and wheelchair at first and slept in a hospital bed with trapeze in our living room since I couldn't do stairs. Graduated to crutches towards the end of the 8-week period, but hated them. Walked crutch-free after 9 weeks, with a limp. That's when I went back to work. I had in-home PT the first 8 weeks, then in the PT's office for a good while after that.
I hope that you won't have lasting pain from this injury. I have had achy pain on long, hilly bike rides on the back side of my ilium or sacrum ever since. It's worse when I am in a more aerodynamic position, less when sitting more upright. A TENS unit helped once I finally tried that, years later. But I can hike, walk, and run pain-free, a real blessing.
Good luck, and feel free to ask more questions -- I am typing this in a rush as we're about to head out the door. So VERY sorry this happened to you!
