Guevara-Villazón F, Boissiere L, Hayashi K, et al. - Researchers sought to compare and examine the general outcome of multi-rod constructs with a matched two-rod cohort, to better understand the differences and the similitudes. A retrospective matched cohort study was conducted to enroll individuals with adult spinal deformity (ASD) that underwent surgical correction with long posterior instrumentation (more than five levels), pelvic fixation and a minimum 1-year follow-up. They selected thirty-three individuals with multi-rod construct and 33 matched with a two-rod construct from a database with 346 ASD-operated individuals. A significant improvement was recorded in both groups with surgical management in the radiographical and HRQoL parameters. There were no significant differences between groups for the postoperative radiographical, clinical and perioperative parameters. There was no major disadvantage in the use of a multi-rod construct. Besides, this supports the benefit of applying multi-rod constructs to avoid implant failure.
