ClinConnect Summary
This clinical trial is studying a device called The Tether™ to help treat children and adolescents with progressive idiopathic scoliosis, specifically those with Lenke Type 1 curves. The main aim of the study is to gather information on how safe the device is and what benefits it may provide to patients. Participants who receive The Tether™ during their spine surgery will need to attend follow-up visits, which are standard care after surgery, to monitor their progress.
To be eligible for this study, patients should be diagnosed with progressive idiopathic scoliosis, be still growing (skeletally immature), and have a significant curve in their spine (between 30° and 65°). They should not have had prior spinal surgery in the same area, and they must have tried and been unable to effectively use a back brace. Additionally, participants must be able to attend follow-up visits and provide consent for the study. Overall, this trial aims to ensure the ongoing safety of The Tether™ device and evaluate its potential benefits for young patients with scoliosis.
