UK-developed device for fixing bone fractures piloted in Gaza, Sri Lanka, and Ukraine.
UK bioengineers have developed a low-cost, easy-to-manufacture stabiliser for bone fractures to help in regions where such devices are expensive or in short supply and people sometimes resort to homemade options.
To address these needs, the scientists set out to develop a low-cost, locally manufacturable unilateral external fixator for LMICs, which would also address the shortage in these countries and "enable the surge capacity" in conflict regions or unforeseeable events, explained the authors.
The device was tested in cadaver leg bones - where it was found to have similar stiffness to commercial devices - as well as undergoing mechanical testing that simulated pressure on the device to demonstrate its ability to keep the bones in position over a longer term. It is currently being tested in Sri Lanka for road traffic accidents, and in Gaza and Ukraine where it is being used for gunshot wounds and other conflict trauma.
The authors acknowledged some limitations of their design and testing, including that clinical results are not presented and neither are results on the ability of the device to be cleaned, sterilised, and reused - factors that are currently being researched.
