3D printed prosthetics for Ugandan schoolchildren

3D printed prosthetics get Ugandan schoolchildren back on their feet

Although we’ve heard numerous stories about how 3D printing has helped enable hundreds of those in need of prosthetic limbs, a majority of the cases have been located in the United States or the United Kingdom where 3D printers or 3D printing providers are becoming increasingly common and access to a 3D printer is getting easier than ever before.  While this is excellent news, there are still many world locations where affordable prosthetic devices – and even 3d printers in general – are needed and could be used perhaps even more than those located in more developed Western countries.

In the meantime – thankfully – various organizations and 3D printing providers have been picking up 3D printing jobs as needed to ensure that those who need the prosthetic devices the most are getting the proper care that they need.  More recently, the University of Toronto and charity Christian Blind Mission took it upon themselves to produce prostheses for a Ugandan schoolboy who had been in need of a prosthetic device for years.

The schoolboy, Jesse Ayebazibwe of Kisubi, Uganda, tragically had his right leg amputated after he was hit by a truck after walking home from school three years ago.  Since then, the nine-year-old has been maneuvering with the aid of crutches – however they have since made it difficult to play or move around.  “I liked playing like a normal kid before the accident,” he said.

Thanks to the support of a local orthopaedic technologist, Moses Kaweesa of the Comprehensive Rehabilitation Services (CoRSU) in Uganda, Ayebazibwe was able to use an infrared scanner and some 3D modeling software to create a prosthetic solution for the young boy before shipping the files to Canada to be 3D printed.

“The process is quite short, that’s the beauty of the 3D printers,” said Kaweesa.  “Jesse was here yesterday, today he’s being fitted.”

While Ayebazibwe previously wore a traditional-style prosthesis last year, his new 3D printed prosthesis is among the first in a trial that could see more 3D printed prosthetic device across Uganda for others in need – thanks in no small part to the efforts of Kaweesa.

Currently, the entire country of Uganda has just 12 trained prosthetic technicians for over 250,000 children who have lost limbs, which are often due to fires or congenital diseases.  At $12,000, a portable solution consisting of a laptop, a 3d scanner and a 3d printer is not cheap – however when considering the impact that a portable prosthetic device system could have on over 200,000 children in need – in northern Uganda alone, many people have lost limbs due to decades of war where chopping off limbs was a common reality.

“There’s no support from the government for disabled people … we have a disability department and a minister for disabled people, but they don’t do anything,” said Kaweesa.  “You can travel with your laptop and scanner.”

Upon receiving his 3D printed prosthetic, Ayebazibwe was clearly ecstatic.  “(It) 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 kilometers 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.

First 3D printed knee for cat!

Cyrano the cat gets a second chance to be able to use a leg deteriorated from bone cancer again, with the help of the first 3D printed knee joint ever made for cats! 🙂

A Weighty Dilemma

It’s the kind of diagnosis you dread. When Cyrano developed bone cancer in his left hind leg, his owners wanted to get him the best treatment possible to bring him back to full health. After successful radiation treatment that eliminated the tumour, Cyrano went into full remission. Unfortunately, because of the invasive nature of the cancer, Cyrano was left with bone deterioration in his distal femur and he was unable to use his painful knee joint. In cases like this, surgeons normally choose to amputate the affected limb; however, at 26 lbs, Cyrano wouldn’t be able to support his weight with only three legs. Undeterred, Cyrano’s owners enlisted the help of experienced veterinary surgeon and orthopaedic specialist Dr Denis Marcellin-Little and his long-time collaborator Ola Harrysson, Professor of Industrial and Systems Engineering at North Carolina State University to create a custom solution for their beloved pet.

Getting Cyrano Back on His Feet

Dr Marcellin-Little and Prof Harrysson have worked with Materialise using Additive Manufacturing in surgeries for over 10 years. With amputation out of consideration, they felt that 3D Printing could provide an ideal solution for Cyrano because of its ability to create small but detailed parts to exacting specifications. Cyrano would thus become one of the very first cats to receive a miniature, limb-sparing total knee arthroplasty. Starting with CT scans of both hind legs, Dr Marcellin-Little and Prof Harrysson used Materialise’s Mimics Innovation Suite to generate accurate 3D models of Cyrano’s leg. Adapting the design of a knee implant used in dogs, in collaboration with BioMedtrix, an animal implant company, they then created a miniature implant that fit to the exact anatomical structure of Cyrano’s leg, and the surgical plan needed to successfully realize the procedure. Because of the small size of the bones, the integrated ability of the Mimics Innovation Suite to engineer parts on a personalised anatomical model facilitated a process that would have otherwise been extremely difficult to manage and perform accurately.

Building Strength and Integration Features Into Implants

Knowing the bone structure around the joint was weak, the implant was designed with stems that would anchor it into the bones. Materialise technology partner EOS then printed the implant using cobalt chromium, a metal strong enough to support Cyrano’s weight and the wear and tear that daily use would exert on the thin parts. Building the implant by Direct Metal Laser Sintering meant that mesh and porous areas that would promote integration of the implant into the bone could also be built into the piece as it was being created. These features, only achievable using Additive Manufacturing, provide enhanced long-term stability over traditional implants, giving surgeons a new option for non-standard cases such as Cyrano’s that can be tailored exactly to their needs. Since his surgery Cyrano has returned to his family, and although he now walks with a limp, he can move freely again with full use of his joint. With 3D Printing now entering the veterinary realm, cats are one step closer to experiencing their full nine lives.
