Prosthetics Health Article

Definition

Prosthetics is the branch of surgery concerned with the replacement of missing body parts with artificial substitutes.

Description

While prosthetics is defined as a branch of surgery, those involved in this profession include the surgeon, nurse, prosthetist, and physical therapist. Others involved in treatment can include a prosthetics technician, prosthetics assistant, rehabilitation counselor, and social worker.

The goal of prosthetics is to replace all or part of a missing limb so that a patient can function. This replacement can involve fitting a man with an artificial leg so that he can walk, or equipping a woman with an artificial hand so that she can hold objects. An artificial appliance is often called a "prosthetic" or a "prosthesis." Prosthesis can also refer to the replacement of a missing part with a prosthetic.

Historical perspective

The practice of prosthesis dates back to ancient times. During the sixteenth century, a German knight was

known as Gotz of the Iron Hand because of his prosthetic. The appliance's movable fingers enabled the knight to hold a sword.

Wood, however, served as the primary material for prosthetics until the twentieth century. In the aftermath of two world wars, research led to the development of prosthetics made of aluminum alloys, metals, and fiber material.

Throughout the centuries, prosthetics were made with mechanical devices and rubber band-type material to allow their wearers to grip objects and move more easily. Movement devices in prosthetics now include hydraulic knees and computer-programmable hands that sense muscle movement.

Legs, arms, feet, and hands are the most commonly known artificial appliances. Other prosthetics include artificial eyes, hip joints, breasts, and heart valves. Prosthodontics is the branch of dentistry concerned with the replacement of teeth.
