I've heard that some surgeon put in plates, screws, and wires to hold together a back or neck. Can that cause problems later?
As with anything, hardware like screws, plates, and wires can break when they are inside the human body. There are also times when pieces of the hardware move to an area where they aren't supposed to be. Luckily, this doesn't happen very often. If it does, another surgery is needed to repair, remove, or replace the hardware.
