Subject must be physically and mentally willing and able to comply with postoperative and routinely scheduled clinical and radiographic evaluations 10. Subject assent and parent/legal guardian consent obtained and documented

Primary
| Measure | Time frame |
|---|---|
| Current primary outcome measure as of 27/10/2021: Benefit of MIScoli™ system in halting the progression of the major curve (Cobb angle) of scoliosis in growing subject measured by examination of x-rays at baseline and 3-year follow-up. The x-rays will be reviewed by an independent contract laboratory organization. _____ Previous primary outcome measure as of 25/01/2021: Benefit of SCOLI-TETHER System in halting the progression of the major curve (Cobb angle) of scoliosis in growing subject measured by examination of x-rays at baseline and 3-year follow-up. The x-rays will be reviewed by an independent contract laboratory organization. _____ Previous primary outcome measure: Benefit of SCOLI-TETHER System in halting the progression of the major curve (Cobb angle) of scoliosis in growing subject measured by examination of x-rays at baseline and 5-year follow-up. The x-rays will be reviewed by an independent contract laboratory organization | — |
