I can't fault the doctors here from my limited experience, fortunately.
Last year, I had a crash on my motorbike and managed to absolutely obliterate my wrist bone (right distal radius). From the x-rays, the surgeons didn't have high hopes; they said I'd likely only get about 20% mobility back, but did their best anyway. The bone was shattered into 15 major pieces, then thousands of fragments.
After a fair few hours in surgery, 6 weeks off work, and great physio, I've got to the point of about 95% mobility. I have a metal plate, several screws, and a kick-ass scar, as well as a bruised ego and a lesson learned.
I'm very thankful to the people who took care of me, but I do understand that this is a small slice of what goes on. Not everyone is so fortunate.
