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.|

Who Works on Prosthetic Limbs?
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.
Orthotisis - Provide a range of
splints, braces, and special footwear to aid movement, correct deformity, and relieve discomfort.
The prosthetisis and orthotisis technicians work together
in different aspects of helping a patient through replacing a limb.
