Abstract
This invention is a pedicle screw (), comprising a threaded rod () having a longitudinal axis (XX) and a head () in which there is a channel () adapted to receive a spinal support rod, and a means for blocking the rod; the channel is formed such that its longitudinal axial plane (P) is inclined relative to the longitudinal axis (XX) of the threaded rod. The head () of the screw being made up of two flanks (), a threaded hole () is formed in one of them; the inclination of the channel () relative to the axis of the treaded rod () makes it possible to place a tool for blocking the rod in the channel without this tool coming into contact with the muscle tissues delimiting the incision. Moreover, the threaded seat () permits the positioning of instruments without obstructing the channel for passage of the rod.
