An instrument for distracting at least two adjacent vertebrae and/or retaining them in a spaced apart position. Anchor screws are secured to the adjacent vertebrae and tubes of a retainer-distracter instrument frame are slid down over the anchor screws, after which the anchor screws are positively secured to the tubes of the frame. The frame includes a structure for moving the arms and hence the anchor screws and vertebrae toward and away from each other. According to a method of operation, after the anchor screws and frame are attached, a separate distracter distracts the vertebrae away from each other, whereupon the instrument acts only as a retainer to hold the vertebrae apart.
Instrument servant à écarter au moins deux vertèbres contiguës et/ou à les retenir dans une position écartée. Des vis d'ancrage sont fixées aux vertèbres contiguës et les tubes d'un instrument de retenue et d'écartement sont passés au-dessus de ces vis d'ancrage qui sont ensuite vissées aux tubes de cette structure. Cette dernière sert à déplacer les bras et, de ce fait, les vis d'ancrage et les vertèbres les unes vers les autres ou à les éloigner les unes des autres. Selon un procédé, après la fixation des vis d'ancrage et de la structure, un écarteur séparé écarte les vertèbres l'une de l'autre, l'instrument ne servant alors qu'à retenir les vertèbres à distance l'une de l'autre.
