A hospital-based cluster stratified randomization control study will be conducted to investigate spinal growth in Early Onset Scoliosis patients between 5 and 9 years of age. Patients must have a major coronal curve measuring over 50 degrees and be undergoing Magnetically Controlled Growing Rod treatment. We will be studying 6-week lengthening intervals compared to 16-week lengthening intervals on spinal growth within 3 years.
The Magnetically Controlled Growing Rod (MCGR) system consists of growing rods similarly implanted as with traditional approaches, but with subsequent noninvasive distractions. The implanted growing rods are magnetically controlled and adjusted outside the body using an external remote controller (ERC) following initial surgical insertion. No incision or anesthesia are used for rod lengthening procedures and they are performed by the surgeon in an outpatient or office setting. The purpose of this study is to determine the effect of a 6-week lengthening interval compared to a 16-week lengthening interval on spinal growth in Early Onset Scoliosis patients between 5 and 9 years of age with a major coronal curve over 50 degrees undergoing MCGR treatment within 3 years.

| MAGEC® Spinal Bracing And Distraction System | Device | The magnetically controlled growth rod (MCGR) system is a remotely distractible, magnetically controlled growing rod. The remote capabilities allow for less invasive and less time-consuming outpatient distraction visits, which solves many of the problems facing current growing rod technologies. The MCGR system allows for more frequent lengthenings, and the implanted growing rods can be lengthened more often, which allows MCGR to better approximate normal spine growth compared to Traditional Growing Rods. |

| Health related quality of life: questionnaire | Early onset scoliosis 24 item questionnaire; This is a patient reported outcome measure for quality of life, parental/financial burden, and satisfaction (4 main domains). There are 11 sub-domains: General health, pain/discomfort, pulmonary function, transfer, physical function, daily living, fatigue/energy level, emotion, parental impact, financial impact, and satisfaction. Within satisfaction, there is child and parent satisfaction. The raw score for each item is from 1-5. This can be turned into scale scores of 0-100. The higher values represent a better outcome. Average sub-domain scores as well as domain scores can be calculated. | 3 years |
