Investigating the potential advantages of a new design metacarpophalangeal joint

The outcomes of finger joint replacement are typically poor, with most designs suffering from early failure. This paper describes collaborative research between academia, industry and surgeons to develop a novel implant design for replacement of the finger joints. The initial research was undertaken while Shepherd held a Leverhulme Trust Special Research Fellowship. The design concept has been patented (US2006167559) and an exclusive license agreement is being discussed with a major medical device company (Professor Alan Johnstone, Consultant Orthopaedic Surgeon, a.johnstone@nhs.net). This research has the potential to improve the lives of patients affected by arthritis of the finger joints.
