Prosthesis
Pronunciation: pros-THEE-sis
An artificial device that replaces a missing or non-functional body part, including limbs, joints, or sensory organs.
Full Definition
A prosthesis is an artificial device designed to replace a missing or non-functional body part, restoring form and/or function. In clinical documentation, 'prosthesis' (singular) and 'prostheses' (plural) are the standard spellings; editors must be vigilant against the misspelling 'prosthetics' when referring to a single device. Prostheses may be internal (implanted) or external (worn), and documentation should specify which type. The term encompasses limb prostheses, ocular prostheses, dental prostheses, and craniofacial prostheses, among others.
Usage
Usage note: Do not use 'prosthetics' as a synonym for a single device; 'prosthetics' refers to the field or discipline, not the device itself. Plural is 'prostheses', not 'prosthesises'.
