Abstract

In recent years, there has been a paradigm shift in the treatment of early-onset scoliosis. This change is manifested by a propensity
to avoiding or delaying fusion surgeries due to their many potential shortcomings. Many surgeons gravitate towards conservative
measures and growth-friendly implants such as magnetic expandable growing rods. Still, such interventions are not impeccable.
This case report discusses 8-year-old girl with early-onset scoliosis managed with magnetic expandable rods after failing conservative management. The results were promising at first. However, catastrophic failure was diagnosed after multiple successful
elongations necessitating discarding the system and changing the construct to conventional growing rods.
