Glossary of Terms
ABC - American Board for Certification in Orthotics & Prosthetics, Inc.
AK - Above the Knee Amputee.
AMPUTATION - The surgical removal of all or part of a limb or extremity such as an arm, leg, foot, hand, toe, or finger.The surgical removal of all or part of a limb or extremity such as an arm, leg, foot, hand, toe, or finger.
BK - Below the Knee Amputee.
CASTING - A plaster or fiberglass mold is created from the residual limb and used to create a replica of the limb.
CHECK SOCKET - A socket made of clear plastic used to evaluate the fit of the socket design to the residual limb.
CO (CERTIFIED ORTHOTIST) - Orthotist who has passed the certification standards of The American Board of Certification in Orthotics & Prosthetics, and maintains certification through mandatory continuing education program and adherence to the Canons of Ethical Conduct.
COINSURANCE - Your share of the costs of a covered health care service, calculated as a percentage (for example, 20%) of the allowed amount for the service. You pay coinsurance after you’ve met your deductible. For example, if the health insurance plan’s allowed amount for an office visit is $100 and you’ve met your deductible, your 20% coinsurance payment would be $20. The health insurance plan pays the rest.
CP (CERTIFIED PROTHETIST) - Prosthetist who has passed the certification standards of The American Board of Certification in Orthotics & Prosthetics, and maintains certification through mandatory continuing education program and adherence to the Canons of Ethical Conduct.
CPO (CERTIFIED PROTHETIST/ORTHOSIST - Prosthetist/Orthotist who has passed the certification standards of The American Board of Certification in Orthotics & Prosthetics, and maintains certification through mandatory continuing education program and adherence to the Canons of Ethical Conduct.
DEDUCTIBLE - A deductible is the amount you have to pay out-of-pocket for expenses before the insurance company will cover the remaining costs.
DEFINITIVE PROSTHESIS - The permanent prosthesis (usually provided after a preparatory/temporary) that is designed to last for several years.
DOFFING - Taking the orthosis or prosthesis off.
DONNING - Putting the orthosis or prosthesis on.
DYSTROPHY - Pathologic loss of muscle mass.
FABRICATION - Procedure of mechanically creating a custom device.
FLEXIBLE INNER LINER - Used as a cushion between the liner and socket.
FUNCTIONAL LEVEL - K-levels are defined by Medicare based on an individual's ability or potential to ambulate and navigate their environment.
GAIT - Walking.
K-LEVELS - K-levels are a rating system used by Medicare to indicate a person’s rehabilitation potential. The system is a rating from 0 through 4 and it indicates a person’s potential to use a prosthetic device if they had a device that worked well for them and they completed rehabilitation to use the device properly.
K-LEVEL - Does not have the ability or potential to ambulate or transfer safely with or without assistance and a prosthesis does not enhance their quality of life or mobility.
K-LEVEL 1 - Has the ability or potential to use a prosthesis for transfers or ambulation on level surfaces at fixed cadence. Typical of the limited and unlimited household ambulator.
K-LEVEL 2 - Has the ability or potential for ambulation with the ability to traverse low level environmental barriers such as curbs, stairs or uneven surfaces. Typical of the limited community ambulator.
K-LEVEL 3 - Has the ability or potential for ambulation with variable cadence. Typical of the community ambulator who has the ability to traverse most environmental barriers and may have vocational, therapeutic, or exercise activity that demands prosthetic utilization beyond simple locomotion.
K-LEVEL 4 - Has the ability or potential for prosthetic ambulation that exceeds basic ambulation skills, exhibiting high impact, stress, or energy levels. Typical of the prosthetic demands of the child, active adult, or athlete.
LINER - The gel or urethane material that provides cushion to the residual limb, helps protect the skin from irritation and breakdown.
OUT OF POCKET - The most you’ll have to pay for covered services in a policy period (usually one year). After you reach this amount, your health plan will pay 100% for covered essential health benefits.
PRACTITIONER - Allied health professional who is specifically educated and clinically trained to manage the provision of comprehensive orthotic and prosthetic care (commonly used term to refer to orthotists and prosthetists).
PREPARATORY DEVICE - An artificial limb that is designed, fabricated and fitted soon after surgery; the prosthesis is worn as the residual limb is healing.
PROSTHESIS - Artificial medical device that is not surgically implanted which is used to replace a missing limb or appendage such as artificial limbs, hands, fingers, feet or toes. Note: this does not include devices, which do not have an impact on the musculoskeletal functions of the body (e.g., artificial eyes or appliances for the eyes, dental plates, and largely cosmetic devices such as wigs, artificial breasts, eyelashes, ears and noses).
PROSTHETICS - Science and practice of evaluating, measuring, designing, fabricating, assembling, fitting, adjusting, or servicing prosthesis under an order from a licensed physician.
PROSTHETIC COMPONENTS - The parts that make up the artificial limb. For example, foot, ankle, socket, pylon, etc.
PYLON - Pipe-like structure used to connect the prosthetic socket to the foot/ankle components.
Rehabilitation- Process of restoring a person who has been debilitated by a disease or injury to a functional life.
RESIDUAL LIMB - Remaining portion of the limb after amputation.
SHRINKER - An elastic material that applies controlled compression to help provide pain relief and reduce swelling.
SOCKS - The sock is knitted to fit the shape of the residual limb worn inside the socket that helps to reduce the friction between the residual limb and the socket and replaces lost volume in the socket due to shrinking of the residual limb. Socks can come in multiple ply.
SOCKET - The portion of the prosthesis that is in contact with the residual limb.
TECHNICIAN - Assists the CO, CP, or CPO during the Fabrication Process.
TRANSFEMORAL - A type of amputation that occurs above the knee.
TRANSHUMERAL - A type of amputation that occurs above the elbow.
TRANSRADIAL - A type of amputation that occurs at the forearm.
TRANSTIBIAL - A type of amputation that occurs below the knee.
