Prosthetic Limbs

A prosthesis is an artificial body part and people with limb loss often wear a prosthesis to replace all or part of an arm, leg, hand or foot. 


A prosthesis is used to replace the function of the missing limb and/or is used for cosmetic reasons.  The plural term for prosthesis is prostheses.



Prostheses are named after the body part they replace.  The term 'trans' is used for a prosthesis where the limb loss begins part way through a long bone (eg.'Trans-Femoral Prosthesis' refers to an artificial limb replacement where the knee joint has been removed and part of the femur or thighbone is intact).  The term 'dis' is used for a prosthesis where the limb loss occurs at the level of a joint (eg.  'Knee Disarticulation Prosthesis' or 'Elbow Disarticulation Prosthesis').  Partial foot or hand prostheses are designed for persons missing only part of their hand or foot.
