Artificial limbs, or prosthetics, have been recorded in history as early as ancient Egypt. Innovations over the centuries mean that many who are missing or have lost a limb, whether through trauma, disease, or congenital condition, can be fitted with limbs that not only look authentic, but also effectuate the movements of human limbs. This wide-ranging work details the kinds of prostheses available today, how they're made, how they work, the challenges that face those who use them, and exciting advances in prosthetic technology. Readers will marvel at these medical wonders as well as the people who fabricate and utilize them.
