This is the crux to something I've been thinking about ever since Roy Harper lost his arm. It seems to me this story has been done. I can think of many, many characters who have lost a limb and got some sort of super-technological limb to replace it. Off the top of my head I can think of Roy Harper, Commander Steel, His grandson Steel, Cyborg, Lex Luthor, Risk, Booster Gold, Emil Hamilton, and even Aquaman. All of them lost an appendage and miraculously got (or in the case of risk could have got) a super-replacement without missing a beat.
This brings up a few questions like... After all these advancements shouldn't there be more super-powered organs and limbs available to everyone? What kind of a hero would hide this advancement from the greater population when they could vastly improve the lives off so many other people? Cyborg was saved by technology that was suppose to be used according to the first issue of Tales Of The New Teen Titans to help veterans "whose bodies were destroyed in war." That technology despite it's success was never used for the veterans it was intended to help. Are these heroes inspirational to people with similar disabilities or are they too easily restored and thus an arrogant depiction and flat version of what it is really like to loose a limb or organ.
To me there is too much death and dismemberment in comic books as it is. I don't like it when my favorite hero is killed. This is made worse by the weak resurrections and patch jobs that come later. I understand the characteristics of having a character die every once in a great while to establish an unsure world but dead heroes don't sell comics in the long hall so they always get resurrected. Death and dismemberment happens too much to the heroes in comic books. Death is not death and dismemberment is quickly overcome. So... What do you think?
