Title (EN) BONE CUTTING GUIDES FOR USE IN THE IMPLANTATION OF PROSTHETIC JOINT COMPONENTS
(FR) GUIDES DE COUPE D'OS POUR L'IMPLANTATION DE COMPOSANTS D'ARTICULATION PROTHETIQUE
Abstract:
(EN) Improved bone cutting guides enable a surgeon to better gauge required resection characteristics. In one embodiment at least a portion of the guide (204) is transparent (208, 210), thereby enabling the user to optimize cut estimates and to visualize the resection as it is being performed. In another embodiment, at least a portion of the outer surface of the body (404) is shaped to interact with another bone or prosthetic element associated with a joint, thereby enabling the device to function both as a trial and as a cutting guide. In this embodiment (404) as well the guide may be at least partially transparent to improve visualization. Although primarily intended for use in femoral-side knee arthroplasty, the invention is applicable to any procedure which might benefit from improved bone-cutting accuracy.
(FR) La présente invention concerne des guides améliorés de coupe d'os permettant à un chirurgien de mieux évaluer les caractéristiques de la résection à effectuer. Selon un mode de réalisation, une partie au moins du guide (204) est transparente (208, 210), ce qui permet à l'utilisateur de faire des estimations optimales de coupe et d'observer la résection en cours d'intervention. Selon un autre mode de réalisation, la forme d'une partie au moins de la face externe du corps (404) permet l'interaction avec un autre os ou avec un élément prothétique associé à une articulation, ce qui fait qu'on peut utiliser le dispositif aussi bien pour des vérification que pour guider la coupe. Selon ce mode de réalisation (404) également, le guide peut être au moins partiellement transparent pour une meilleure observation. Bien que l'invention soit initialement prévue pour l'arthroplastie fémorale du genou, elle convient particulièrement à toute intervention susceptible de profiter d'une amélioration de la précision de la coupe de l'os.
