Broken wrist. I did not recognize the term 'osteosynthesis
surgery' but that means something like 'patch':

For that wrist to work normally without pain they have to remove all of that metal and all four screws or else arthritis will occur later in life. Nibali isn't a spring chicken and should have known a lot better than trying to catch himself with this hand rather than just using them to deflect himself into a rollover.
That's not true. Hardware usually stays in unless it becomes infected or causes mechanical pain. Hardware may limit movement for a variety of reasons, but it does not cause arthritis (absent infection). In fact, there is a lower rate of arthritis with ORIF than with closed reduction and casting. I had the plate and screws in my right ankle removed because they were misplaced, and pressure from my ski boot caused the screw heads to pop through my skin and bleed. I was the orthopedic Jesus with my ankle stigmata. I have a rod in my right tibia and broke a locking screw and had that removed, too. I still have the rod. I have well installed plate in my left ankle that will remain there until death. I have a tiny plate and screws in my hand that will also stay put.

This is suppose to be a cycling technology newsgroup. Should you be
getting the latest technology such as titanium or carbon fiber?
"Biomechanics of bone-fracture fixation by stiffness-graded
plates in comparison with stainless-steel plates"
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1192810/
Or, maybe go high tech and have the bones stitched back together?
"New surgical techniques - stitching up bones"

Jay didn't say that his hardware *wasn't* titanium. I think it's pretty
commonly used, but I could be wrong. I'm saying that based on a tour
some 15 years ago that my brother gave me of the orthopedic
rod/plate/screw manufacturing facility where he worked, but the details
are foggy. What I really remember were the *extensive* quality-control
requirements.

My removed plate and screws were SS. I think Ti is more common for implants. My IM nail (rod) may be Ti. There is ton of QC on these things and they have to receive FDA approval under Medical Device Act, which is typically 510(k) approval, a much shorter process for new iterations of common products. Bad designs still creep through, as you can tell from all the class action ads.

What I remember wasn't QC of design issues - that must have been there
too - but rather QC of the input materials. When they got some stock,
rather than waiting for it to be approved for metallurgical purity (at
whatever standard) before using it, they cut off a sample for testing.
Then they rigorously tracked every single part they made from that piece
of stock so they could tie it back to the sample, in case the sample
came back from testing "not OK". Kind of an "every screw has a serial
number" thing.
