Description
Dr David Kirwan discusses advancements in orthopedic technology, particularly focusing on dual mobility (DM) bearings in hip replacements. Dr Kirwan emphasizes the increasing popularity and usage of DM bearings, citing their historical development and benefits such as improved stability and reduced friction. A dual tank model of DM bearings is proposed, along with insights into the failure rates associated with conventional models. The presentation outlines concerns over issues like early and late dissociation of DM bearings, neck notching, and the mechanical stresses affecting their longevity. A novel poly-bearing design is introduced that aims to prevent common failure mechanisms and is poised for clinical trials. The discussion concludes with a call for further exploration into pricing strategies and competitive advantages for adopting this new technology in orthopedic practices.
