Bracing and fusion surgery have shown varied effects on pulmonary outcomes. Vertebral Body Tethering presents a growth-sparing alternative that might mitigate these effects by reducing biomechanical disruptions. Aim was to evaluate changes in pulmonary functions during the course of the follow-up after VBT surgery.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>Retrospective cohort study including patients who underwent Thoracic, Thoracolumbar and Bilateral VBT surgery with a minimum 24\u00a0months follow-up. Forced Vital Capacity (FVC%), Forced Expiratory Volume in the first second (FEV1%) and FEV1\/FVC ratio were evaluated at multiple time points.

Preoperatively, the median Sanders was 3 (1\u20137) and the median Risser was 0 (\u2212\u20091\u20145). The mean MT curve of 50.8\u00ba\u2009\u00b1\u200911.0\u00ba was corrected to 26.0\u00ba\u2009\u00b1\u20097.3\u00ba at 6\u00a0weeks, which was modulated to 22.4\u00ba\u2009\u00b1\u200913.4\u00ba.
