If you've ever had to wear a splint on any part of your body, you'll know that not only are they uncomfortable, but they can be chunky and ugly too. That may not be the case for much longer.

A researcher from the University of Loughborough has developed a new computer software concept that will allow doctors to customize and 3D print breathable, stylish, slimline splints even if they have no experience using computer aided design software (CAD). The aim of the software is to allow those with no real knowledge of design to create wrist splints for rheumatoid arthritis sufferers.

"I wanted to give clinicians the ability to make splints they have not been able to make before," said Abby Paterson, the PhD student who created the software. "They can improve the aesthetics, the fit, and integrate extra bits of functionality they couldn't do before."

Using an Objet Connex machine, the splint can be printed as an integrated object made up of many different materials. This allows for features such as rubber hinges and padding. Not only are the splints lighter and more attractive, but they are also cheaper to produce since the design and manufacture process, which used to be done together, can be separated out. As the splints are so customizable in terms of color, fit, fastenings and latticework, it's also likely that people would wear them more—in which case, they would be more cost-effective for organizations like the NHS.

The software is still currently in the prototype phase, and Paterson believes it will take around 18 months before it is completely ready. In the meantime, she is currently pursuing a cost analysis. The new splints definitely sport better designs than their predecessors, but if it also appears that they will be much better value to create, there is likely to be huge demand for the service—both in terms of doctors and patients.

Around 400,000 people in the UK suffer from rheumatoid arthritis, and the splints provide pain relief, rest, and joint protection. The reaction from medical professionals who deal with the condition has been positive according to Paterson. "The practitioners were very excited by new, novel ideas to expand the possibilities available to them, such as integrated rubber borders for increased comfort," she said.

Paterson and Richard Bibb, also of Loughborough University, believe they need some funding in order to perfect the CAD software, but otherwise there is no reason why the technology won't be taken up by hospitals. "We are in the development phase. The research has proved that this is desirable and the clinicians want it. We know there's lots of potential," said Bibb.
