I had the plate and screws taken out of my collar bone a few years ago because it was uncomfortable.
Surgeon was happy to do it. Generally they prefer not to have to operate as opening you up is an infection risk so they avoid surgery if possible.
I’m very glad I did it. The morphine hit afterwards was a once in a lifetime experience 😀
The only downsides were I had to take it easy for a few months whilst the screwholes healed over – the bone was weak until that happened + as it meant they cut me open for a third time (I’d had a bone graft as well as the initial op to fix me) the nerve damage to my skin is permanent – although barely noticeable day to day and definitely less uncomfortable than the plate.
If you regularly wear a rucksack – for riding or walking – a plate can be very uncomfortable
