Oz Benderman, an Israeli industrial designer, has created a transtibial prosthetic device for children, called FIT, that can be adjusted in height and width to allow for the child’s growth. Benderman says the prosthesis can be mass-produced for less than $10, and is intended to provide sustained mobility to children who lack regular access to medical care, such as those in developing countries.
Using plastic-injection technology, FIT is made from DuPont™ Delrin® 100P acetal resin, polypropylene thermoplastic polymer, and Orfit thermoplastic, and has a notched central rod that allows the device to be adjusted without professional help.
