A brand new process that could revolutionise the reliability and durability of surgical implants, such as hip and knee replacements, has today, 2 December 08, received recognition for its medical and commercial potential by achieving one of the world's most sought after accolades.
A team of researchers, led by the Science and Technology Facilities Council (STFC), has received a Medical Futures Innovation Award for its high technology process designed to coat surgical implants with fibres that, for the first time, will encourage the implant to 'bond' with living bone and to last the lifetime of the patient.
This unique surface engineering process is being developed at the Micro-Nano Technology Centre (MNTC) at STFC. In collaboration with the Electrospinning Company Ltd (TECL) and Anglia Ruskin University, the concept will be taken forward under the guidance of a Medical Futures team, and eventually exclusively licensed to TECL, a spin out company of STFC.
This advanced nanotechnology technique builds on an existing technique known as electrospinning, and will utilise a vastly superior electrospinning source to create bespoke fibrous materials. Electrospinning is a process that uses an electrical charge to turn polymers into extremely thin fibres that are 'spun' to form a mat of fine fibres. It is seen as a platform technology for the medical sector with a wide range of applications including tissue regeneration and drug delivery. The MNTC has developed systems to increase the production rate of nanofibres which has been previously prevented this technology from being adopted by industry.
In this case, nanosized hair- like structures, a thousand times thinner than the width of a human hair, are electrospun at MNTC and added to the surface of an orthopaedic implant to create a 'living interface' between the artificial implants and living bone. Not only does this improve the performance of the implants it also significantly increases their durability to last the lifetime of the patient. Any stress on the implant is relieved, making it more reliable and durable. Additionally, it is also possible to add a unique biological coating that can facilitate growth and improve the bonding of healthy tissue to the implant, primarily benefitting patients with osteoarthritis in the aging population and sports injuries in the younger population.
