BIRG contributed to the endoprosthetic session in this event with its esteemed speakers Prof. Jörg van Schoonhoven (D-Bad Neustadt / Saale) and Dr. Stephan Schindele (CH-Zurich) who both gave impressive overviews over the successful clinical outcomes and their long-term experience with the ulnar head prosthesis (UHP) resp. the PIP joint endoprosthesis (CapFlex). Right after the lectures, interested attendees took the chance for additional questions and comments to both experts.
