Hospital-Based Cluster Trial: Magnetically Controlled Growing Rods Using Distraction Intervals
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.
