The ProPortion foundation has started working on setting up a “leg bank” in Colombia! Together with design agency reggs, Livit Orthopedics and the TU Delft they have started exploring the possibility of setting up a social enterprise that offers an affordable and qualitative prosthesis. They are aiming to develop a prosthesis for between €100-250. Very exciting project, hopefully they will create a beautiful novel solution!

This man, who had both arms amputated after a devastating accident, has built himself two fully functional lower-arm prostheses. Even with grasping function! Incredible low-cost engineering. Check it out:

An unusually old and beautiful prosthetic arm. It is even spring-loaded and allows wrist rotation and motion. What a beauty!



An amazing initiative of Mick Ebeling who went to South Sudan, took his 3D printer with him, and is now bringing hope to all the 50.000-plus amputees that live there. Amazing project.

A knitted prosthesis is a creative project by Frank Naus. There is no other information, it’s just a nice idea.

This award-winning lower-leg prosthesis, created by Bob Giesberts at the University of Twente, the Netherlands, is specifically designed to be produceable in a mobile workshop. The design is inspired by the ZIP prosthesis and is co-created with several parties both in the Netherlands and Indonesia. It can be produced within 2 hours, and does not require any heavy machinery, making it ideal for mobile workshops. It is created by wrapping synthetic cast tape around the stump, which is subsequently pressed into place using a water-pressure system, thereby ensuring equal distribution of force on the stump.

The quality and durability of the prosthesis are currently being tested by the DARE Foundation in Jakarta, Indonesia

In the David Werner collection some of the most basic assistive solutions to hand-amputations are described. In case no other resources are available these are the bare-essentials. The manual describes how to create simple tools to hold objects like spoons or pencils. It also shows examples of grabbing hands, but sadly does not explain complete production.

MUKTI, active since 1986, is a social organisation dedicated to helping physically challenged people. Their goal is to provide free artificial upper and lower limbs and calibers to all amputees and polio victims that are seeking help. They achieve this by setting up prosthetic camps and providing training in a wide variety of countries, mostly India, Srilanka, Bangladesh. Amputees from rural and semi urban areas who report to Mukti to get the free artificial limbs can also benefit from the free boarding and lodging facilities offered by Mukti.


Solution: Unknown

Locations: India, Srilanka, Bangladesh
(Trainings have been given in Nepal, Venezuela, Brazil, Bolivia, Mexico, Moscow, Guatemala, West Indies, Malawi, Ghana and Nigeria.)

Using patient feedback, and with a focus on disabled people living with a budget below $4 a day, the organisation D-Rev has created a affordable knee joint, that doesn’t only work, but also looks great. The ReMotion Knee, D-Rev’s first product, is the result of a collaboration between India’s Jaipur Foot and Stanford University. Through a no-cost license with Jaipur Foot the knee has now been fitted to over 4000 patients.
