Lemans JVC, Wijdicks SPJ, Castelein RM, et al. - A prospective cohort study was conducted to evaluate curve correction and -maintenance, spinal growth, complication rate, and health-related quality of life following spring distraction system (SDS) treatment. Researchers included all primary- and conversion individuals (conversion from failed other systems) with SDS and ≥ 2 years follow-up. They compared radiographic parameters preoperatively, postoperatively, and at the latest follow-up. They enrolled 24 skeletally immature early-onset scoliosis patients (18 primary and 6 conversion cases). In this 2-year follow-up results from this prospective cohort study, results revealed that the concept of spring distraction may be feasible as an alternative to current growing spine solutions. The results indicated that curve correction and growth could be maintained satisfactorily without the need for repetitive lengthening procedures. The outcomes suggested that as in all growth-friendly implants, complications and reoperations could not be prevented, which emphasizes the need for future improvement.
