Core Tip
Core tip: Magnetically controlled growing rods (MCGR) are a novel treatment approach for early onset scoliosis which is gaining increases clinical usage. Since its introduction, numerous modifications have been implemented to improve the performance of the construct, however, these modifications are often over-looked in current published series. This study evaluated the effect of the addition of the keeper plate to MCGR, finding that it had a significant impact on decreasing the rate of post-operative distraction failures. Despite the impact of this modification, 25% of published articles included mixed implant designs in their series, potentially inflating reported complication rates.
