Title
(DE) VORRICHTUNG ZUR KOPPLUNG EINER PROTHESE AN EIN WIRBELSÄULENSEGMENT
(EN) APPARATUS FOR COUPLING A PROSTHESIS TO A SPINAL SEGMENT
(FR) APPAREILS PERMETTANT D ACCOUPLER UNE PROTHÈSE À UN SEGMENT RACHIDIEN
Abstract
(EN) A method for coupling a prosthesis to a spinal segment in a patient includes the steps of selecting first and second reference points disposed along the spinal segment and pre-operatively measuring a target distance. The target distance extends between the first and second reference points while the patient is in a preferred posture such as the standing position. A prosthesis is coupled to the spinal segment and the prosthesis is then intra-operatively adjusted in order to set the distance between the first and second reference points based on the target distance.
(FR) La présente invention concerne un procédé permettant d'accoupler une prothèse à un segment rachidien chez un patient. Ledit procédé inclut les étapes consistant à sélectionner des premier et second points de référence disposés le long d'un segment rachidien et à mesurer de manière pré-opérationnelle une distance cible. La distance cible s'étend entre les premier et second points de référence tandis que le patient se trouve dans une position préférée, telle que la position debout. Une prothèse est accouplée au segment rachidien, et ladite prothèse est alors ajustée de manière intra-opérationnelle afin de fixer la distance entre les premier et second points de référence, sur la base de la distance cible.
