breakthrough could prevent Hip Implant Replacement

World-leading researchers from the University of Sheffield have identified a molecule which can be targeted to reduce the loosening of hip implants by preventing toxic metal entering into bone cells.

Hip implants rely on the normal functioning of bone cells to achieve fixation of the implant with the bone. However, small metal particles released from hip implants, due to friction between the moving surfaces, have been shown to be toxic to the surrounding bone cells. This causes the implant to loosen in the bone and often leads to patients requiring second surgery to replace the failed implant.


Using X-ray light from the Diamond Light Source (the UK’s synchrotron science facility at Harwell Science and Innovation Campus, Oxfordshire), researchers were able to map the locations of metals inside bone cells. The findings, published in the Journal of Orthopaedic Research, show that the location of the metals that are released from implants is different inside bone building and bone destroying cells.

Dr Alison Gartland, Senior Lecture from the University’s Academic Unit of Bone Biology, said: “The fact that we found metal ions in different places within the two types of bone cells suggest that they get into the cells by separate ways. When investigating how the metals entered bone cells we found that when we blocked a molecule called the P2X7 receptor using a specific drug, the entry of metals into the bone cells was reduced. These results are really exciting because, if we can prevent the entry of the metal into these cells, we can hopefully prevent the metal joint from failing.”

Surgical replacement of the joint using artificial metal implants is the most effective way to restore activity and reduce pain and disability in osteoarthritis sufferers. The research was funded by the National Institute for Health Research (NIHR) and in collaboration with Diamond Light Source.

European Robotics Forum 2015

erf2015The sixth edition of European Robotics Forum (ERF) will take place in Vienna, Austria

This 3-day event (March 11-13, 2015) is a meeting point for at least 350 scientists, companies and robotics officials from the European Commission. The program is designed to provide an opportunity for the companies and researchers to meet and interact in workshops and seminars in order to expand their networks, gather the latest relevant information, and build new business and collaborations thereby strengthening the potential of European robotics.

After its start in San Sebastian in 2010, this annual event has quickly become the most influential meeting of the European robotics community. Researchers, engineers, managers, and a growing number of entrepreneurs and business people from all over Europe come together to discuss topics and contents which also have an immediate impact on the roadmapping process for Robotics in Europe.
