Title (EN) APPARATUS AND METHOD FOR SPINAL FIXATION AND CORRECTION OF SPINAL DEFORMITIES
(FR) APPAREIL ET PROCEDE D'OSTEOSYNTHESE VERTEBRALE ET DE CORRECTION DE DEFORMATIONS DE VERTEBRES
Abstract:
(EN) This device comprises a connection element (4) between a rod (1), or other longitudinal implant, and a bone anchorage screw (3) in the degenerative vertebra. This connection element (4) includes a ring (8) so dimensioned that the rod (1) is capable of extending therethrough. The ring is provided with screws (14) for clamping to the rod (1) and is radially extended by a cylindrical arm (9) adapted to be secured to the bone anchorage screw (3) and to be clamped on the screw. The arm (9) and the ring (8) constitute a unit in one piece. The invention enables the surgeon to avoid having to produce additional deformations of the rod (1) when it is in presence of non-aligned pedicles by leaving to the surgeon complete liberty as to the position of the two axes of the bone anchorage screw (3) and of the rod (1). The invention further contemplates using the lateral connection element to facilitate contouring the longitudinal implant within the patient, or $i(in situ) to segmentally and globally correct spinal deformities in all degrees of freedom.
(FR) L'invention concerne un dispositif comprenant un élément de connexion (4) situé entre une tige (1), ou un autre implant longitudinal, et une vis (3) d'ancrage d'os, dans la vertèbre dégénérative. Cet élément de connexion (4) comporte un anneau (8) de dimensions telles que la tige (1) peut s'étendre à travers celui-ci. Cet anneau est prévu avec des vis (14) destinées à être serrées contre la tige (1), il est prolongé radialement par un bras (9) cylindrique adapté pour être fixé à la vis (3) d'ancrage d'os, et serré contre cette vis. Le bras (9) et l'anneau constituent une unité d'une pièce. Cette invention permet à un chirurgien d'éviter de devoir provoquer des déformations supplémentaires à la tige (1) lorsque celle-ci est en présence de pédicules non alignés, en lui laissant une liberté complète quant à la position des deux axes de la vis (3) d'ancrage d'os et de la tige (1). Cette invention concerne en outre l'utilisation de l'élément de connexion longitudinal dans le patient, ou la correction $i(in situ) de déformations de vertèbres de façon globale et par segments, avec une liberté totale.
