Goodbye with plaster: they invent a glue that can restore broken bones in just a few minutes

The bones are quite qualified to restore alone when they break. However, the process is usually long and usually needs some help. For this plasterIn fact, so the bone does not move at the time that is necessary for recovery. Sometimes, however, The holes have holesThe holes that are free from the injury or, for example, by removing the tumor. In these cases, the bone can take something more to restore it on its own. It could be helped 3D -toy, But this is still a relatively slow process. Therefore, the team Korean scientists I tried with the most interesting alternative: Hot adhesive pistolA field yes, like those used in Crafts or DIY.

It is logical that it is introduced into the gun, is not normal glue, but Biological glue This was specially developed for Repair broken bones. Despite this, the results of the first tests spent in rabbits seem quite promising.

And this is enough for a few seconds to make the bone completely filled and fixed. Then the bone cells themselves can grow to replace the glue; But at least the holes are filled quickly, without the need for gypsum or any other external help.

What is usually done for repairing broken bones?

As we have already seen, usually for the repair of broken bones, they are allowed to regenerate themselves. Usually, when it comes to Fractures of the limbs The plaster is placed to prevent movement that can be interference. In other cases, this is simply recommended The greatest possible restThe field on the other hand, if there are holes, this is usually not enough.

In these cases, the most modern measure consists of Scan the hole that should be filled and print the frame in 3D What facilitates the proliferation of bone cells themselves. This measure is engaged per week In the full repair of broken bones. In addition, some forecast is necessary, since everything should be scanned in advance.

As explained in New scientistWhen you need to fill the bone hole during or after surgery It can be programmed a good option, since planning is allowed. On the other hand, in emergency cases, when broken bones are produced Accidentally or in an unexplored operation In advance, the measure of three -dimensional forests are outdated. An adhesive gun comes here.

How does an adhesive pistol work?

This adhesive pistol was developed by scientists from University SungkyunkwanIn South Korea. They used a regular gun from which they are used for crafts, but changed their content and temperature at which it works. The glue mainly consists of Hydroxyapatitis and polycaprolactoneThe first field is a mineral consisting of crystalline calcium phosphate. Usually it is 50 % of the volume of human bones. As for the second ingredient, it is a biodegradable polyester that can be discarded naturally in the body after the bones are completed by regeneration.

In addition, these scientists tried to add two antibiotics: Gentamycin and VancromicinIn this way, not only broken bones are repaired, but also Possible infections are prevented.

Finally, they persecuted in court to ensure that this was correctly placed, they were only necessary 60 ºC. Conventional adhesive guns heat up to 100 ° C, but this can be harmful to the bone.

In tests held in Rabbit women With fractures around the centimeter, the glue was sealed in just a few seconds, filling the hole and allowing, already without risk, the fracture is aggravated, new bone cells are plucked. 12 weeks later, rabbits did not encounter health problems, and the bones were still completely sealed.

Logically, We will have to try in public before throwing bells on the flyThere are some experts who do not believe that this will finally reach life. Others are very optimistic in this. We will have to wait to see what will happen. In any case, the fact of converting an adhesive pistol for crafts in a valuable medical tool is already quite surprising.
