Abstract
The aim of this study was to investigate the immediate and 6-month effects of a scoliosis traction chair on scoliosis rotation and Cobb angle. The scoliosis traction chair has been used clinically for 10 years and has been part of previous studies, but has not been the focus of any previous study. Our goal was to test the scoliosis traction chair’s ability to de-rotate the spine to create scoliosis correction. Fifteen patient files were retrospectively selected for study. Patients were radiographically studied in a proprietary traction chair to evaluate impact on Cobb angle and apical vertebral rotation. Six-month follow-up results were recorded. Six-month results showed an average overall Cobb angle increase of about 7°. Patients with in-chair apical de-rotation showed 9° of Cobb angle improvement, while those with increased in-chair apical rotation showed an average 16° progression. Scoliotic curves whose apical rotation worsened on stress radiography showed deterioration of the curve at 6 months. Those with improved apical rotation showed Cobb angle corrections at 6 months. Since progression of scoliotic curvatures was observed in our cohort of patients after 6 months of home and clinical use, it is imperative that further studies attempt to qualify which patients and scoliosis curve patterns are best suited for the scoliosis traction chair.
Highlights
N Scoliotic curves whose apical rotation worso ened on stress radiography showed deterioraN tion of the curve at 6 months
The purpose of this study is to evaluate the device’s ability to derotate the spinal curvature in the thoracic spine, as claimed by the manufacturer, due to the known complexities of the ribcage biomechanics in scoliosis patients.[5]
We report the 6-month Cobb angle measurements of patients using this device for scoliosis treatment
Summary
N Scoliotic curves whose apical rotation worso ened on stress radiography showed deterioraN tion of the curve at 6 months. Those with long-term outcomes of the device have been collected and published to date. The purpose of this study is to evaluate the device’s ability to derotate the spinal curvature in the thoracic spine, as claimed by the manufacturer, due to the known complexities of the ribcage biomechanics in scoliosis patients.[5] We report the 6-month Cobb angle measurements of patients using this device for scoliosis treatment
