Introduction: Magnetic Expansion Control (MAGEC) Spinal Growing Rods are a novel treatment for early-onset scoliosis (EOS). Although its efficacy is supported by the literature, it is not without complications. Materials and Methods: The aim of this study was to retrospectively analyze a series of 37 cases treated with MAGEC between 2014 to 2019. We performed a retrospective study and divided the population into two groups: GI (primary procedures with MAGEC) and GII (conversions from traditional system to MAGEC). Results: The study included 19 girls and 18 boys with a mean age of 8 years and a variety of etiologies. The average postoperative follow-up time for Group I (n=28) and Group II (n=9) was 3.6 years. The average preoperative angular value (AV) of scoliosis was 64° (39°-101°) and kyphosis 51° (7°-81°). The postoperative scoliosis AV was 41° (17°-80°) and kyphosis 34° (7°-82°). We found 2 rod ruptures and one proximal union kyphosis, two proximal screw loosenings, one MAGEC distraction system failure, and one surgical site infection. Conclusions: Although our preliminary results are short term, they suggest that MAGEC could be an effective method.
