Abstract
The device includes tubular elements capable of being temporarily fastened at the level of pedicle screw heads arranged to be connected by an implantable curved rod, and at least one rod intended to be movably inserted into slots of each tubular element, to align them for the correction of the spinal column by translation, tilting, and rotation of the vertebrae in the three planes of space. Each tubular element is configured in such a way that it can be coupled with the outside of the pedicle screw heads. The rod forms an alignment and handling rod, being capable of acting, as it moves, on rings for simultaneously displacing the curved rod. Each ring is assembled with the ability to slide along the tubular element, and to be height-adjustable to compensate for dimensional deviations between the alignment and handling rod and the curved rod.
