What is the definition of a prosthesis?

A prosthesis is defined as an artificial body part designed to replace a missing or damaged body part. This can include limbs, such as arms and legs, as well as other body parts like dentures for teeth or artificial joints. The primary purpose of a prosthesis is to restore function and improve the quality of life for individuals who have lost a part of their body due to injury, disease, or congenital conditions. By providing a replacement that mimics the appearance and functionality of the original body part, prostheses allow patients to regain mobility and engage in everyday activities, thus enhancing their overall well-being.

In contrast, natural body parts refer to those that occur naturally in the human body and do not apply to this definition. Similarly, a surgical procedure involves operations conducted to treat or diagnose medical conditions but does not describe a body part itself. Lastly, medication pertains to substances used to treat illness or manage symptoms, which is distinctly different from the concept of a prosthesis.
