Trope-a-Day: Artificial Limbs
Artificial Limbs: Quite possible, but a disfavored technology in Imperial society; in the modern era, when biotechnology is also advanced, it tends to be preferred for internal solutions, or at the least it should be used to ensure that the bionic technology is well integrated with the meat: bones reinforced with carbon fiber, muscles interwoven with myomar, a skin supplemented with a layer of armor gel, and a well-concealed mass driver hidden mostly within the flesh are much more likely than simply chopping off a perfectly good arm and replacing it with a mechanical prosthetic one.
(And, of course, cloned grafts are the way biotech solves the pure replacement issue.)
