Prosthesis
Pronunciation: pros-THEE-sis
An artificial device that replaces a missing body part, typically a limb, used to restore functional ability and appearance.
Full Definition
A prosthesis (plural: prostheses) is a fabricated device that substitutes for an absent body part, most commonly an upper or lower limb lost through amputation or congenital absence. In rehabilitation medicine, prosthetic fitting and training are integral components of amputee rehabilitation programs. Editors must carefully distinguish between 'prosthesis' (replaces a missing part) and 'orthosis' (supports an existing part). Related abbreviations include AK (above-knee) and BK (below-knee) prosthesis, as well as IPOP (immediate postoperative prosthesis). The plural 'prostheses' should be used rather than 'prosthesises.'
Usage
Usage note: Plural is 'prostheses.' The adjectival form is 'prosthetic' (e.g., prosthetic limb). Do not use 'prosthetic' as a standalone noun in formal clinical writing.
