Smashing the time it takes to repair our bones

05.12.2006
New research by Queensland University of Technology is helping scientists better understand how bone cells work and may one day lead to the development of technology that can speed up the time it takes to heal fractured and broken bones.

Dr Hannay said his device replicated the mechanical and electrical stimulants which occurred naturally in the body to repair fractured and broken bones.

"This device is about trying to grow bone tissue in the same environment our body grows bones. I have taken bone cells and put them in the physical environment they would experience in the body, and then varied the stimulants to extract a beneficial environment for tissue growth," he said.

Dr Hannay's research has advanced the understanding of how bone cells can be stimulated to heal factures and has for the first time combined the artificial reproduction of both mechanical and electrical stimulants.

"Previous research has looked at both of these stimulants individually, but not together, neglecting the fact that both are occurring in normal healthy bone during fracture healing"

He said by combining the two stimulants, a synergistic effect was produced.

"That means when you apply both the mechanical and electrical stimulants together a result greater than the sum of the two stimulants applied individually is achieved. It creates a greater output," he said.

Dr Hannay said that unfortunately when bones fractured or broke, especially in older people, the healing process could stall.

"We find bones can get half way through the healing process but won't heal properly and with an aging population this is a growing problem for orthopaedic surgeons to accommodate and one that is not easily solved with current methodologies," he said.

"In the future we might be able to make a device utilising these combined stimulants that could be attached to the body and help heal the bone."

Additionally, normal fractures that would otherwise heal successfully could be accelerated with the use of these stimulants.

Dr Hannay said normal fractures in young, healthy people took approximately six to eight weeks to heal.

"It might be possible to significantly reduce the healing time. That would be the goal."

Dr Hannay graduated from QUT with a PhD from the Faculty of Built Environment and Engineering.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
