Advances in prosthetics are rapid.

Draft page – more information coming soon.

Is it prostheses or prosthetics? A prosthesis is an artificial body part (plural = prostheses) whereas the adjective is used to describe a particular type, for example a prosthetic hand. Prosthetics is the medical speciality studying and applying prostheses.
