An orthosis assisting the foot and ankle
Orthosis, which comes from the Greek word "orthos" (meaning "straight") refers to an external, custom-made medical device that is used to support, align, prevent, or correct deformities of a body part, or to assist a physical weakness or improve the function of movable parts of the body, according to the Canadian Association for Prosthetics and Orthotics.
Types of Orthoses
Splints are a type of orthosis.
The medical brace, such as the knee brace or ankle brace, is the most common example of an orthosis. Other orthoses include elbow supports, protective face masks, "halo" or cervical collars (for spine injuries), and the in-shoe foot orthotic.
Primary Applications
Knee braces are one of the most common orthoses.
Orthoses are always associated with devices that are used outside of the body. Internal medical devices and implants, such as pacemakers and hip replacements, are not orthoses.
Common Uses
The most common parts of the body where orthoses are used are the spine, the hip, the knee, the foot and the hand.
Orthosis Design
Many design factors affect the functionality of orthoses. Key qualities include the weight of the device; ease of application and removal; adjustability and breadth of fit; affordability; and durability.
Orthotics
The area of medicine that specializes in the design, fabrication and fitting of orthoses is known as orthotics. This field is in many ways similar to prosthetics, which focuses on the design, fabrication and fitting of artificial body parts.
Becoming an Orthotist
In order to become an orthotist, you must earn a bachelor's degree program in orthotics and complete a residency program under a licensed professional. To become certified in the United States, orthotists must pass a certification exam given by the American Board for Certification in Orthotics and Prosthetics.
