In total, 28 silk-based screws were inserted into 6 rats in which they functioned efficiently for eight weeks.
In accordance to the researchers, the outcome of the trial suggests that employing silk screws could spare patients the issues of getting rid of metal devices due to the fact they could dissolve in the body.
The screws are also not witnessed on X-rays, which means that it would be less complicated for medical doctors to observe how a fracture is progressing soon after an operation.
Scientists say that the original aim is to use silk-based screws to deal with facial injuries, but that the gadgets have the likely for the treatment of a assortment of diverse kinds of bone fractures.
Co-writer of the examine Dr Samuel Lin, from Harvard Health-related School, explained, “Not like metal, the composition of silk protein could be related to bone composition.
“Silk resources are extremely robust. They sustain structural stability beneath quite large temperatures and stand up to other intense conditions, and they can be readily sterilised.”
Dr David Kaplan, from Tufts University, additional: “A single of the other huge advantages of silk is that it can stabilise and supply bioactive parts, so that plates and screws manufactured of silk could in fact deliver antibiotics to avert infection, pharmaceuticals to improve bone regrowth and other therapeutics to assistance healing.”
