A3D-printed prosthetic limbs: the next revolution in medicine

V
           



John Nhial was barely a teenager when he was grabbed by a Sudanese guerrilla army and forced to become a child soldier. He spent four years fighting, with guns almost too heavy to hold, until one day the inevitable happened: he was seriously injured, treading on a landmine while he was on morning patrol. “I stepped on it and it exploded,” he recalled. “It threw me up and down again – and then I tried to look for my leg and found that there was no foot.”
            His comrades carried him back to base camp, but there was hardly any medical care available. It took 25 days before he received proper treatment, during which time he developed tetanus down one side of his body. Finally, Nhial was put on a flight to the Kenyan border, his life only saved when he was handed over to a Red Cross team.Now, a decade later, he lives in a Juba refugee camp, having suffered further troubles in the conflict of South Sudan. He plays wheelchair basketball for his country, although he relies on a prosthetic lower leg to struggle around the muddy, sprawling camp. But at least his hands are free to carry things such as food and water, unlike those on crutches.
            The World Health Organization estimates there are about 30 million people like Nhial who require prosthetic limbs, braces or other mobility devices, yet less than 20% have them. Prosthetics can involve a lot of work and an investment of  time and financial cost to patients, who may have to travel long distances for treatment that can take five days.
            However, technology may be hurtling to the rescue – in the shape of 3D printing. It has been revolutionising aspects of medicine since the start of the century, just as it has had an impact on so many other industries, from cars to clothing. Perhaps this is not surprising, given that its key benefit is to enable the rapid and cost-efficient creation of bespoke products. There are few commercial products that need to suit a wider variety of shapes and sizes than medical devices made for human beings.
            Experts have developed 3D-printed skin for burn victims, splints for infants, facial reconstruction parts for cancer patients, orthopaedic implants for pensioners. The fast-developing technology has churned out more than 60m customised hearing-aid shells and ear moulds, while it is daily producing thousands of dental crowns and bridges from digital scans of teeth, replacing the traditional wax modelling methods used for centuries.So it is no surprise that the technology has begun to stir interest in the field of prosthetics, even if sometimes by accident.
