3D printers get Ugandan amputees back on their feet

Doctors amputated Ugandan schoolboy Jesse Ayebazibwe’s right leg when he was hit by a truck while walking home from school three years ago.

Afterwards he was given crutches, but that was all, and so he hobbled about. “I liked playing like a normal kid before the accident,” the nine-year-old said.

Now an infrared scanner, a laptop and a pair of 3D printers are changing everything for Jesse and others like him, offering him the chance of a near-normal life.

“The process is quite short, that’s the beauty of the 3D printers,” said Moses Kaweesa, an orthopaedic technologist at Comprehensive Rehabilitation Services (CoRSU) in Uganda which, together with Canada’s University of Toronto and the charity Christian Blind Mission, is making the prostheses.

“Jesse was here yesterday, today he’s being fitted,” said Kaweesa, 34.

In the past, the all-important plaster cast sockets that connect prosthetic limbs to a person’s hip took about a week to make, and were often so uncomfortable people ended up not wearing them.

Plastic printed ones can be made in a day and are a closer, more comfortable fit.

The scanner, laptop and printer cost around $12 000, with the materials costing just $3.

Ayebazibwe got his first, old-style prosthesis last year but is now part of a trial that could lead to the 3D technology changing lives across the country.

 Life-changing technology

The technology is only available to a few, however, and treatment for disability in Uganda in general remains woeful.

“There’s no support from the government for disabled people,” said Kaweesa. “We have a disability department and a minister for disabled people, but they don’t do anything.”

There are just 12 trained prosthetic technicians for over 250 000 children who have lost limbs, often due to fires or congenital diseases.

The 3D technology is portable and allows technicians to work on multiple patients at a time, increasing the reach of their life-changing intervention.

“You can travel with your laptop and scanner,” said Kaweesa, adding that the technology could be of great use in northern Uganda, a part of the country where many people lost limbs during decades of war between the government and Lord’s Resistance Army rebels, who specialised in chopping off limbs.

After receiving his first 3D socket Ayebazibwe was overjoyed. “I felt good, like my normal leg,” he said. “I can do anything now – run and play football.”

The boy’s 53-year old grandmother, Florence Akoth, looks after him, even carrying him the two kilometres to school after his leg was crushed and his life shattered. She too is thrilled.

“Now he’s liked at school, plays, does work, collects firewood and water,” said Akoth, who struggles to make ends meet as a poorly-paid domestic worker caring for five children.

Sitting on a bench outside the CoRSU fitting room were three young children and their parents.

“This is her first time walking on two legs,” said Kaweesa, pointing at a timid young girl who lost both her legs in a fire.

“Because they’ve seen other kids walking, playing, they realise they’ve been missing that,” he said “Once you fit them they start walking and even running.”

How 3D printing is changing lives in South Sudan

In 2010, Mick Ebeling, founder of a company called Not Impossible, spearheaded the creation of the Eyewriter, eye-tracking glasses using open-source software, to allow paralysed people to draw and communicate using only their eyes.

Then, in November last year, Not Impossible printed a prosthetic hand that allowed a teenager to feed himself for the first time in two years. But that was just the beginning.

[Last week], Ebeling stunned audiences at the International Consumer Electronics Show (CES) in Las Vegas with the story of Project Daniel.

Late last year, he set up the world’s first 3D-printing prosthetic lab and training facility in Sudan’s Nuba Mountains. The first “patient” was a boy called Daniel, who had had both his arms blown off at the age of 14.

The boy, now 16, was living in a 70 000-person refugee camp in Yida, South Sudan. On November 11, he received the first version of a prosthetic left arm. It was named after the boy himself: the Daniel Hand. And it enabled him to feed himself for the first time in two years. According to Ebeling, he also ate chocolate for the first time.

With the assistance of an American doctor, Tom Catena, the team then set about teaching others to print and assemble 3D prostheses. By the time the Americans returned home, local trainees had printed and fitted another two arms, underlining the project’s lasting benefit beyond the presence of the Not Impossible team.

Equally astonishingly, Project Daniel successfully unfolded in a region where fighting was escalating, and where the people taught to use the 3D printers had barely any knowledge of computers.

“We’re hopeful that other children and adults in other regions of Africa, as well as other continents, will utilise the power of this new technology for similar beginnings,” says Ebeling. “We believe Daniel’s story will ignite a global campaign. The sharing of the prostheses’ specifications, which Not Impossible will provide free and open source, will enable any person in need, anywhere on the planet, to use technology for its best purpose: restoring humanity.”

Robohand
The Daniel Hand was originally designed at the Not Impossible headquarters in Venice, California (United States), using crowdsourcing to pull in “a dream team of innovators”. Prominent among them was the South African inventor of the Robohand, Richard Van As, a master carpenter from Johannesburg.

The team also included an Australian neuroscientist and a 3D printing company owner. The project was supported by precision engineering company Precipart and by chipmaker Intel, which included Ebeling in its own events at CES this week.

“We are on the precipice of a can-do maker community that is reaching critical mass,” says Elliot V Kotek, Not Impossible’s content chief and co-founder. “There is no shortage of knowledge, and we are linking the brightest technical minds and creative problem-solvers around the globe. Project Daniel is just the tip of the proverbial iceberg.”

While Project Daniel focuses on medical benefits of 3D printing, the project proves that the ultimate benefit the technology can bring is limited only by the human imagination. – Gadget.co.za
