The present invention relates to a device for correcting scoliosis, comprising a pair of distraction rods (2, 3) and a member (4) for linking the distraction rods provided with a means (8) for guiding each of the rods relative to each other inside said linking member. Said device also comprises at least one member (6) for suspending the distraction rods (2, 3) and is capable of imparting flexibility to and exerting a longitudinal preload on the rods so as to increase comfort and prevent the arthrodesis of the vertebrae of the spine of a patient fitted with the correction device. Said device finally comprises a structure for cushioning and translatably locking the distraction rods into the connection member. Said structure is only operative when compressive stresses of the spine of a patient are applied to the distraction rods (2, 3) so as to absorb and counter said compressive stresses and increase the comfort of the patient while preventing the arthrodesis of the spinal vertebrae of a patient.La présente invention concerne un dispositif de correction de la scoliose, comportant un couple de tiges (2, 3) de distraction, et un organe de liaison (4) des tiges de distraction, muni de moyens de guidage (8) de chacune des tiges lune par rapport à lautre à lintérieur dudit organe de liaison. Ce dispositif comporte en outre au moins un organe de suspension (6) des tiges de distraction (2, 3) apte à conférer une souplesse et exercer une précharge longitudinale sur les tiges pour augmenter le confort et éviter larthrodèse des vertèbres du rachis dun patient instrumenté du dispositif de correction. Il comporte enfin une structure damortissement et de blocage des tiges de distraction en translation dans lorgane de liaison, ladite structure étant active uniquement lors defforts de compression du rachis dun patient sur les tiges de distraction (2, 3) de façon à absorber et sopposer aux dits efforts de compression et augmenter le confort du patient en évitant larthrodèse des vertè
