Effectiveness and safety of a one-yearly elongation approach of growing rods in the treatment of early-onset scoliosis: A case series of 40 patients with definitive fusion.

Background: Early onset scoliosis (EOS) can lead to marked spine and chest wall deformity and often to profound cardiopulmonary compromise. Nowadays, treatment benefits from the possibility of a growth-friendly surgical approach to avoid early spinal fusion. Growing rod spinal implants allow maximizing spine and thorax growth during childhood, performing lengthening procedures traditionally approximately every 6 months.
