🦴 Faster healing of bone fractures – making them three times stronger

• Japanese researchers have developed a new treatment method that uses plasma radiation to accelerate the healing of complex bone fractures.
• The treatment has been successfully tested on laboratory rats, and the healed bones were 3.5 times stronger compared to conventional treatments.

A new technique for faster bone healing

Researchers at Osaka Metropolitan University in Japan have developed a method that uses non-thermal atmospheric plasma to treat bone fractures. The plasma radiation has been shown to promote faster healing and significantly strengthen the bones.

This technique is particularly promising for treating complex fractures that typically require surgery and long recovery periods.

The research team conducted tests on two groups of rats. One group with normal fractures and another with so-called "non-healing" fractures. The results showed that the plasma radiation had no significant effect on the normal fracture group but had a markedly positive effect on bones with non-healing fractures. They healed faster and became about 3.5 times stronger than with conventional treatments.

Strengthening effects and future applications

In laboratory studies at the cellular level, it was observed that the activity of a protein, which is an indicator of osteoblast differentiation, increased after irradiation for five to fifteen seconds. This indicates that the maturation of bone cells was promoted by the treatment.

According to Associate Professor Hiromitsu Toyoda, this technique, combined with existing treatment methods for fractures, could contribute to safer bone union and shorter recovery times in the future.
