Badanie tribologiczne implantów sztucznych dysków kręgosłupa
Journal Title: Tribologia - Year 2011, Vol 240, Issue 6
Abstract
W artykule omówiono metody leczenia dysfunkcji kręgosłupa za pomocą implantowania sztucznych krążków międzykręgowych. Wskazano na materiałowe i konstrukcyjne wymagania, które powinien spełniać implant. Podano wyniki badań tribologicznych prowadzonych na symulatorze kręgosłupa zaprojektowanym i wykonanym w Instytucie Obróbki Plastycznej w Poznaniu.
