Jiang F, Simões L, Ouellet J, et al. - A retrospective radiographic reliability study was performed to evaluate the validity of EOS 3D imaging technology in the determination of vertebral rotations in the spine of patients with previous instrumentation. Researchers conducted a retrospective review of 31 patients with adolescent idiopathic scoliosis who had undergone instrumented fusion and postoperative computed tomography (CT) scans of the spine. This study’s findings demonstrate that in the instrumented levels of the spine, EOS 3D morphological analysis of vertebral rotational difference indicated significant difference and unacceptable variance in comparison to CT measurement.
