"Bone to receive a fastener rod spinal system to introduce a spinal rod, and.Instruments for introducing a spinal rod is elongated in a channel in the form of U of a bone fastener and to manipulate a bone fastener.A system for introducing an elongated spinal rod, comprising a fastener having a head bone, the head including a top end, a bottom end.And a pair of side walls connected to the bottom end defining an elongated U-shaped channel having a first longitudinal axis and a top opening located at the end of the top.The opening of the top and the channel defines a passage configured to receive additional spinal rod and each side wall defined in a first side of the edge, and a secondThe end face, the second face of the end opposite the first side of the edge.An element encaixante bone extends from the outer edge of the bottom of the head for anchoring the fastener of bone to bone.The system comprises in addition a tool to introduce the rod in the channel in the shape of U. the tool includes a first member having a distal end and a proximal end.The distal end is configured to drive the rod through the passage to introduce the rod in the channel in fonna u through the open top.A second member defines a second longitudinal axis substantially perpendicular to the first longitudinal axis.The second member has first and second ends.The second end having a pair of jaws to hold the tool to one of the side walls of the head of the bone fastener so that the second member is provided outside of the passage of the SAHYour spinal cord and, preferably, so as not to interfere or block access to the open top.The first member is operationally associated with the second member so that the first member is pivotable relative to the second member and linearly in a direction parallel to the second transladu00e1velThe longitudinal axis between the first and second ends of the second member along the second longitudinal axis to enter the spinal rod through the opening of the top, in the passage.
