That's strange. I thought current wisdom was to leave screws and plates in unless there's a reason like pain or restriction of movement or religious issues (no foreign bodies to be buried at death). My screws and plate in my shoulder stayed in and my sisters knee screws as well. Second surgery carries risks.

I was told to not to fall on my shoulder again as I could punch the plate and screws through the bone. My vote would be to see if you can avoid metal fittings if you can. Much longer to heal after surgery...
