Summary:A crosslink member for securing spinal rods is disclosed having connector ends that include a brace and a locking member, each having an arcuate face resting on and securing a spinal rod. The locking member is secured by a cam member that rotates relative to the locking member and that cams against the connector to displace the cam member. The crosslink includes a male connector with a cylindrical cross rod received by a cavity in a female connector. The cross rod is secured by a pivotable clamp device in the female connector, and the cross rod connector and female connector may pivot, rotate, and telescope relative to each other. To reduce size without sacrificing pivot sweep, the cross rod has beveled edges, and the cavity of the female connector has windows to provide pivot clearance. L'invention concerne un élément d'articulation en croix destiné à fixer des barres vertébrales, qui comprend des extrémités de raccord munies d'un renfort et d'un élément de verrouillage présentant chacun une face bombée reposant sur et fixant une barre vertébrale. L'élément de verrouillage est fixé par un élément à came qui pivote relativement à lui et agit contre le raccord pour déplacer l'élément à came. L'articulation en croix comprend un raccord mâle muni d'une barre d'accouplement cylindrique logée dans une cavité d'un raccord femelle. La barre d'accouplement peut être un dispositif de serrage pivotant dans le raccord femelle, et le raccord à barre d'accouplement et le raccord femelle peuvent pivoter, entrer en rotation et se télescoper. Pour réduire la taille sans nuire à la portée de balayage, la barre d'accouplement présente des bords biseautés, et la cavité du raccord femelle comporte des fenêtres destinées à ménager un espace libre de pivotement.
