A modified hot glue defender can repair broken bones

Researchers say hot glue rifles are usually used in arts and crafts that can quickly repair damaged bones.

Bones can repair themselves after small injuries, but if there is a vacuum – due to serious shock or removal of the tumor, for example – this space should be filled with either illegal earning or an industrial plug made of material that encourages bone cells to spread.

One of the solutions is to use 3D printers to create completely suitable scales to fill these voids, but this requires remote wiping and manufacturing-a process that takes at least a week. This is a good thing for a pre -planned process to repair a dilapidated joint, for example, but not for emergency shock surgery.

To solve this problem, Yong Song Lee At Sungkynkwan University in South Korea, his colleagues have developed a system that can be applied immediately during one surgery.

They modified the hot glue gun by reducing the temperature that operates from more than 100 ° C to about 60 ° C. They also fabricated a substance that works as a biological vaginal – a mixture of hydroxipate, which makes up 50 percent of the size of natural human bones, and a decomposing calorie called polycaproactone.

Surgeons can use a hot glue pistol to fill bone voids within minutes during surgery, then bone cells can then extend the gap and fix the injury permanently over time.

“He is mainly made of commercially hot glue guns,” says Li. “We can save time and cost.”

Li and his colleagues tested the glue pistol by fixing the long gaps of the centimeter in the thigh bones in the rabbits. In the samples taken after 12 weeks, there were no signs of medical problems or separation of glue and bones. The size of the bone was more than twice its height in the animals that were treated with the glue pistol compared to the dominant animals, as repair was with traditional bone cement.

The researchers also found that they can integrate vancomicin and kantamycin, two anti -bacterial compounds, in the ritual to reduce the risk of infection. Medicines are launched slowly and spread directly on the surgical site over several weeks.

Benjamin Olivier At the University of Nutingham, the UK, which is looking for 3D printed scrutiny, suspects that the hot glue gun will eventually end a widely used solution before wiping the fastest and 3D printing technology.

He says: “Do I think it is an interesting concept? Yes. Can it work greatly? Yes. Do I think it is in the reasonable scope? “But this may not be the thing.”
