PROSTHETICS

What Are Prosthetics?
 
According to dictionary.com, Prosthetics is "The branch of medicine or surgery that deals with the production and application of artificial body parts."
In simple terms, prosthetics are the arms, legs, hands etc. that special doctors attach to a person, as an artificial limb. They are for patients who have lost or were born without a limb for any reason. Prosthetics make that person able to function properly with the help of technology, and hard work assembling together the limbs.
 
An artificial limb is a mechanical replacement for a missing limb. An artificial limb, called a prosthesis, must be light and flexible to permit easy movement, but must also be sufficiently sturdy to support the weight of the body or to manipulate objects. The materials used in artificial limbs include willow wood, laminated fibers and plastics, various metallic alloys, and carbon-fiber composites. One model of artificial leg is made of layers of stockinette cloth coated with plastic; it has duraluminum joints at the knee and ankle, rubber soles on the feet, and a leather cuff cushioning the stump. The cuff fits around the thigh like a corset, holding the artificial leg firmly in place, and connects to a leather belt around the waist. Often, spring joints are employed on foot pieces to give natural-looking movements. Microprocessors and an array of sensors are used to operate the mechanical and hydraulic system of some artifical legs, providing more natural locomotion. Artificial legs may also be secured by suction between socket and stump. Artificial arms, not having to support the weight of the body, may be made of lighter metals and plastics. They are usually strapped to the trunk and controlled by a shoulder harness. Artificial hands vary in structure and utility; research and development has resulted in devices that are both cosmetic and functional.

Prosthetisis - Provide the best possible artificial replacement for patients who have lost or were both without a limb. A prosthetic limb should feel and look like a natural limb.
