Confronting a post-pandemic new-normal-threats and opportunities to trust-based relationships in natural resource science and management.

Natural resource governance is inherently complex owing to the socio-ecological systems in which it is embedded. Working arrangements have been fundamentally transformed throughout the COVID-19 pandemic with potential negative impacts on trust-based social networks foundational to resource management and transboundary governance. To inform development of a post-pandemic new-normal in resource management, we examined trust relationships using the Laurentian Great Lakes of North America as a case study.

Periprosthetic aseptic osteolysis in total ankle replacement: cause and management.

Friction at the bearing surface results in the generation of abraded wear debris of polyethylene. These activate a biologic cascade that may result in significant bone loss and subsequent loss of fixation of the prosthesis.
