Title
(EN) SHOCK-ABSORBING JOINT AND SPINE REPLACEMENTS
(FR) PROTHESES DISCALES ET ARTICULAIRES D'ABSORPTION DE CHOCS
Abstract
(EN)
Numerous joint replacement implant embodiments including a total knee replacement implant including a femoral component (102) having a wheel (104); and a tibial component (106) including a shock-adsorbing component with a piston assembly (110) and spring (112). Said implants contain a cushioning or shock-absorbing member to dampen axial loads and other forces. In many embodiments, fluid is force rapidly from the device wherein compression and dampening is achieved by valves or other pathways that allow for a slower return of the fluid back into the implant as the pressure is relieved.
(FR)
De nombreux modes de réalisation d'implant prothétique articulaire de l'invention comprennent un implant prothétique complet du genou qui comporte un composant fémoral (102) possédant une roue (104); et un composant tibial (106) possédant un composant d'absorption de chocs qui comprend un ensemble piston (110) et un ressort (112). Lesdits implants contiennent un élément d'amortissement ou d'absorption de chocs destiné à amortir des charges axiales et d'autres forces. Dans de nombreux modes de réalisation, un fluide est contraint avec rapidité depuis le dispositif, la compression et l'amortissement étant obtenus au moyen de valves ou d'autres voies qui permettent au fluide de revenir dans l'implant plus lentement à mesure que la pression est relâchée.
