Does prosthesis exist on Ravnica?

I can't say for certain, but the wikis for the material and guild master mention that the only people who would undergo the surgery for regrowing limbs, among other possible improvements, are "Simic members and people requiring prosthetics". The material, Cytoplast, also mentions that it was invented by the guild master, Momir Vig. Based on this, I would assume that there were prosthetic limbs in the years before that point.

I will note that going through the sources on the wiki, I could not find a reference to prosthetic limbs. As a result, I can't be certain that was not just an assumption that was made and added to both wiki pages.
