Claim Text:
1. A surgical device for correcting a deformation of the spinal column, the surgical device comprising: an implantable curved rod, pedicle screw heads arranged to be connected by the curved rod, tubular elements adapted for being temporarily attached at a level of the pedicle screw heads, an alignment rod and a handling rod engaged through the tubular elements to align the tubular elements corresponding to correction of a spine, by translation, tilting, and rotation of vertebrae, wherein each tubular element is formed of two independent semi-tubular portions adapted to be coupled to an outside of the pedicle screw heads and delimit diametrically opposite openings in the tubular elements, wherein a remote first end of each of the independent semi-tubular portions has fittings for coupling said independent semi-tubular portions to each other in jointed fashion beneath a corresponding one of the pedicle screw heads, wherein the implantable curved rod, the alignment rod and the handling rod are arranged in the diametrically opposite openings with the ability to move parallel to an axis of the tubular elements, spacer means being slideable along at least one of the tubular elements and mounted between the handling rod and the implantable curved rod, wherein when the handling rod is displaced downwardly and pushes on said spacer means, the implantable curved rod is simultaneously displaced towards the pedicle screw heads, and a plurality of nuts for fastening the curved rod in the pedicle screw heads, wherein the tubular elements are adapted for receiving, each in turn, an actuating member engaged therein, following removal of the alignment rod and the handling rod from the diametrically opposite openings in the tubular elements, for screwing a nut of said plurality in each of the pedicle screw heads, each nut in turn, thus fastening the curved rod in each of the pedicle screw heads.
