Comparing Use of Radiographs Versus Patient Empowerment (CURVE)

"The patient-empowered follow-up protocol consists of patient-reported outcome measures (PROMs), self-assessment tools and clinical assessment including physical examination. Radiographs will only be taken when progression of the scoliosis (curve progression) or postoperative complications are suspected based on test results and based on the criteria of so called 'sense of alarm'.~Note: Sense of alarm ('niet pluis') is based on any deterioration on the above-mentioned PROMs, self-assessment tool, and clinician-based measurement instruments, which is a signal for the treating physician to consider when a radiograph is appropriate. Sense of alarm is described as any other concern by the orthopaedic surgeon, parent or child which warrants a radiograph. For both the Bunnell Scoliometer (clinical assessment tool) and the Scolioscoop (patient self-assessment tool) a threshold of ≥4° is used."

Routine radiographs are taken at each follow up visit during standard care (to detect possible curve progression or rule out postoperative complications).
