Prosthesis

A prosthesis is an artificial device that replaces a missing body part, which may be lost through congenital conditions, injury, or disease. Prostheses range from purely cosmetic devices designed to replicate natural appearance, to functional devices that restore some degree of movement or capability. Modern prostheses include body-powered mechanical devices actuated by the user's own movement, myoelectric prostheses controlled by electrical signals from residual muscles, and increasingly, 3D-printed open-source designs produced by communities like e-NABLE that combine low cost with high customizability.
