Smaller Rods in Magnetically Controlled Growing Rods are at Increased Risk of Fracture after 3 Years

Purpose Despite evolving technology utilized in growth friendly instrumentation for patients with Early Onset Scoliosis (EOS), device related complications persist. The risk of rod fracture has been cited to be 6-29% in the literature, but no risk factors for fracture in magnetically controlled growing rods (MCGR) have been identified. This purpose of this study was to investigate associations between rod diameter and rod fracture in patients with EOS treated with MCGR. We hypothesized MCGR constructs with …
