This invention relates to methods and instruments for performing disc space preparation and implant insertion from a unilateral approach to the spine through a posterior lateral opening to the disc space. The instruments include spreaders, distractors, reamers, scrapers, cutters, chisels, pushers and implant inserters. A surgical procedure is provided that allows bilateral support of the adjacent vertebrae with at least one interbody fusion device inserted into the disc space via a unilateral approach. Implants for insertion into the disc space are also provided.

La présente invention concerne des procédés et des instruments utiles pour effectuer la préparation de l'espace discal et l'insertion d'un implant à partir d'une approche unilatérale de la colonne par une ouverture postérieure externe débouchant sur l'espace discal. Les instruments comprennent des écarteurs, des séparateurs, des alésoirs, des racles, des fraises, des ciseaux, des pousseurs et des porte-implants. Une intervention chirurgicale est réalisée pour supporter de manière bilatérale les vertèbres adjacentes avec au moins un dispositif de fusion de corps intervertébraux inséré dans l'espace discal au moyen d'une approche unilatérale.
