Title
(EN) GUIDE ASSEMBLY FOR GUIDING CUTS TO A FEMUR AND TIBIA DURING A KNEE ARTHROPLASTY
(FR) ensemble guide pour guider des decoupes sur un femur et un tibia lors d'une arthroplastie du genou
Abstract
(EN)
An assembly for guiding resection of a femur and tibia of a knee joint in preparation for installing a femoral and tibial knee components. For example, the assembly can include tibial and femoral IM rods to which are connected through a torque bolt that allows controlled adjustment of the distraction of the tibia and femur during cut positioning in a range of flexion angles. Also, the assembly is usable with relatively small, noninvasive approaches to the knee joint by way of relatively narrow, low profile components that attach to tibial and femoral IM rods. Further, the assembly includes several quick-release components to allow fast assembly and disassembly in a surgical setting. Each of these aspects, along with the ability of the assembly to accurately guide initial reference cuts to the tibia and femur, promotes an improved outcome for the patient.
(FR)
La présente invention concerne un ensemble pour guider la résection d'un fémur et d'un tibia d'une articulation de genou en préparation à l'installation de composants fémoraux et tibiaux du genou. Par exemple, l'ensemble peut comprendre des tiges IM tibiales et fémorales qui sont raccordées au moyen d'un boulon à couple qui permet un ajustement contrôlé de l'écartement du tibia et du fémur lors du positionnement de la découpe dans une plage d'angles de flexion. De même, l'ensemble peut être utilisé avec des démarches non invasives relativement petites dans l'articulation du genou au moyen de composants compacts relativement étroits qui se fixent aux tiges IM tibiales et fémorales. En outre, l'ensemble comprend plusieurs composants à libération rapide permettant un montage et un démontage rapides dans un environnement chirurgical. Chacun de ces aspects, au même titre que l'aptitude de l'ensemble à guider précisément des découpes initiales de référence sur le tibia et le fémur, favorise un résultat amélioré pour le patient.
