Three-dimensional Effects of Bracing in Adolescent Idiopathic Scoliosis

NCT03298256 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 53

Summary

This study intends to investigate the three dimensional (3D) effect of bracing on the adolescent idiopathic scoliosis (AIS). In particular, it will look at the relationship between frontal deformity correction and changes in the sagittal profile and apical vertebral rotation (AVR) during bracing. The investigators hypothesise that if the thoracic frontal deformity can be controlled with bracing, there will be spontaneous correction of the sagittal plane and rotation deformity through coupling.

Conditions

  • Adolescent Idiopathic Scoliosis

Interventions

RADIATION

EOS X-rays

Full length, orthogonal anteroposterior and lateral X-rays will be taken simultaneously in a standardised standing position, with arms folded anteriorly in 45 degrees . All radiographs will include C7 proximally and the femoral heads distally. 3D reconstruction of the spine can be performed. X-rays will be repeated after the brace is applied, and at intervals of no fewer than 6 months until the brace is weaned off, or if surgical intervention is required. Coronal, sagittal and axial parameters will be calculated from the reconstruction. 3D vertebral wedging will be calculated in the posterofrontal, sagittal and diagonal planes at the apex, 3 superior and 3 inferior vertebrae, as described by Scherrer et al. Changes in the pre- and post-bracing and follow-up parameters can be calculated.
