Prosthetics

Definition

Prosthetics refers to the design and use of artificial devices that replace missing body parts, such as limbs or organs, to restore function and improve quality of life. This field combines engineering principles with medical needs, allowing individuals with disabilities or injuries to regain mobility and independence through tailored solutions. Innovations in materials, biomechanics, and technology have significantly enhanced the performance and comfort of prosthetic devices.
