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: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
