ELI5: Why can't a surgeon replace one's herniated disc with some sort of silicone disc?

They do it for boobies :(

think of a disc as a gusher. if you keep pressing the top and bottom of it, eventually the juice will pop out at the weakest point in the gummy layer. the juice that is inside is what is "herniating" outward but the problem is in the gummy layer because the juice will keep on getting out through that tiny hole. it is this juice that presses a nerve against a bone and causes shooting pains. since the gusher is incredibly sticky, it does a great job of staying between the bones with the help of some ligaments, but removing the entire thing is very difficult and would require much scraping, then if you try to replace it with a peach ring, it wouldn't wouldn't be as good as staying in place because it hasn't had the time to get nice and sticky like the gusher and you had to remove all those ligaments that added support just to to get it into place.
