Abrégé
(EN)

The present invention provides a scoliosis correction device comprising a pair of distraction rods (2, 3) and a member (4) for linking the distraction rods provided with means (8) for guiding each of the rods relative to each other inside said linking member. This device further comprises at least one member (6) for suspension of the distraction rods (2, 3) that can provide flexibility and exert a longitudinal pre-load on the rods in order to augment comfort and prevent vertebral arthrodesis of the spine of a patient instrumented with the correction device. Finally, it comprises a structure for cushioning and locking the distraction rods in translation in the linking member, said structure being active only when compressive forces are applied by the spine of a patient to the distraction rods (2, 3) so as to absorb and oppose said compressive forces and augment patient comfort, thereby preventing vertebral arthrodesis of the patient's spine.
