Description

This study aimed to investigate the use of EOS (bi-planer) imaging and SterEOS reconstruction software to study the efficacy of spinal bracing in adolescent
idiopathic scoliosis (AIS). EOS images of scoliosis patients being treated with bracing were obtained both in and out of their brace. These images were processed using SterEOS software to allow 3D representation, which was then compared to traditional coronal 2D parameters. Over a 12-month period 29 patients were recruited for participation. Of these participants, 25 had a single episode of EOS imaging out of and in their brace. Additionally, 19 of the 25 participants had further episodes of EOS imaging within the study period, separated by mean 144+/-44 days. This allowed a total of 44 EOS single scan episodes for parameter analysis out of, and in the brace. Longitudinal analysis was also performed on the 19 patients who had sequential scans. Participants were mean 13.8 ± 1.1 years old at the first scan. Coronal 2D parameters, specifically Cobb Angle measurement, were accurately reproducible with SterEOS 3D measurements. Across all EOS scans (n = 44) the mean major coronal curve measurement was 42.3 ± 13.3° out of brace and 37.2 ± 13.8° in the brace. This produced a mean correction of 4.6 ± 4.4° (p < 0.05). The correction achieved in this cohort with bracing appeared more modest than those reported in previous studies using traditional 2D coronal curve measurements [1-3]. The mean axial vertebral rotation (AVR) was 10.6 ± 7.1° out of the brace and 9.6 ± 6.8° in the brace, with a mean correction of 1.4 ± 5.3°(p = 0.14). The current study results suggested no significant change in axial vertebral rotation with brace treatment. Notably, in 17 of the 44 AVR measured, the differences were negative. That is, the AVR worsened in the brace. There was a significant moderate correlation between 3D coronal Cobb angle measured and AVR measured out of the brace for all curves. However, the change in Cobb and change in AVR with bracing did not correlate. Over sequential EOS episodes (n = 19), there appeared no significant progression of 3D parameters. There appeared to be a consistent reduction in the scoliosis Cobb angle of the major curve with brace treatment. AVR demonstrated no significant change with bracing, with instances of worsening of AVR in the brace, which was not reflected by Cobb angle measurement. Despite this, bracing appears to have limited curve progression in sequential scans, though not in the anticipated manner of immediate in-brace curve correction.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
