A bone screw polyaxially connected to a seat, the seat including a top opening, first and second rod receiving portions, first and second rod channels. The system is implanted into a first vertebra. The first and second rods are Introduced to the seat through the top opening in a first orientation and connected to the first and second rod receiving portions. The rods are capable of polyaxial movement with respect to the seat for landing the opposite ends of the rods in adjacent seats of screw In other vertebrae. A closure mechanism is configured to lock the polyaxial motion of the rods with respect to the seat and to lock the polyaxial motion of the bone screw with respect to the seat simultaneously or independently. The seat is connectable to a cannula for delivering the first and second rods into the first seat in a percutaneous, minimally invasive procedure.

L'invention concerne une vis à os raccordée de manière polyaxiale à une embase, l'embase comprenant une ouverture supérieure, des première et seconde parties de réception de tige, et des premier et second canaux de tige. Le système est implanté dans une première vertèbre. Les première et seconde tiges sont introduites l'embase à raccordées aux première et seconde parties de réception de tige. Les tiges peuvent avoir un mouvement polyaxial par rapport à l'embase pour disposer les extrémités opposées des tiges dans des embases adjacentes de la vis dans d'autres vertèbres. Un mécanisme de fermeture est configuré pour verrouiller le mouvement polyaxial des tiges par rapport à l'embase, et pour verrouiller le mouvement polyaxial de la vis à os par rapport à l'embase, simultanément ou indépendamment. L'embase peut être raccordée à une canule pour délivrer les première et minimalement invasif.
