New hip resurfacing implant used in clinical trial

8 Feb 2018

A novel ceramic hip resurfacing implant developed at Imperial College London is being trialled in a new study.

The trial is designed to show that the ceramic implant is suitable for both men and women, as conventional methods for hip resurfacing are not suitable for women. The implant being tested is also the first to resurface patients' hips without using metal.

It is hoped that the implant, developed by a team led by Professor Justin Cobb, will lead to better outcomes for younger, more active people requiring surgery. Early results, from the 15 patients treated so far, suggest patients can return to physical activities such as swimming and cycling within six weeks of their operation.

The clinical investigation is funded by Embody Orthopaedic – a spin-out from Imperial Innovations, based around intellectual property developed by a PhD student at Imperial. It is an example of the work carried out by Imperial College Academic Health Science Centre, a joint initiative between Imperial College London and three NHS hospital trusts. It aims to transform healthcare by turning scientific discoveries into medical advances to benefit local, national and global populations in as fast a timeframe as possible.

Professor Justin Cobb, Chief Investigator, said:

"In this safety study, we are ensuring that the H1 hip resurfacing implant can be used safely on patients needing hip replacement surgery. Hip resurfacing is an alternative, more conservative type of surgery that enables a higher level of physical activity than total hip replacement. The metal hip resurfacing implants developed 20 years ago have been highly successful, but some patients have had problems with tissue reactions around the hip owing to the release of metal ions."
