I had both hips done, 7 months and 4 months ago. Today I was sitting at a traffic light, waiting for the green light, when a car came in the other direction, pulled a U turn to get in my lane, never hit the brakes and just plowed into me from behind.
It was a pretty hard impact, we pulled over into a parking lot, I stepped out of the car and walked around it, looked at the damage (rear bumper completely broken lengthwise), checked with the other driver, exchanged info, called the cops and ... only then did I think, wait a minute.. what about my hips?
So I walked out of the car, checked for pain or soreness and realized that not only wasn't I sore anywhere on my hips, but I had a little soreness on my neck. That's about it. I know I stomped down on the brakes to keep myself from going into the car in front, so I put a lot of stress on my 4 month old hip resurface, but no problems at all.
The only bad thing is that the driver is 87 years old and I couldn't be mad at him. Bummer.
