Methods: A total of 468 patients who underwent the Nuss procedure and pectus bar removal for PE from March 2011 to January 2015 were assessed and included into the present study. Results: TS prevalence was 9.4% pre-correctively and 9.8% post-correctively. There was a positive correlation between age and Cobb angle (CA), pre-correctively and post-correctively (both, P vs. 4.5±3.8°, P vs. 4.1±3.3°, P vs. 4.1±3.3°, P=0.078; increased in LG: 6.3±4.9° vs. 7.6±7.2°, P=0.002). In patients with pre-corrective TS, CA after correction was decreased (post-correctively 11.9±10.0° vs. pre-correctively 13.9±6.0°, P=0.090). In addition, post-corrective CA was significantly decreased in EG (pre-correction 13.9±7.4° vs. post-correction 6.6±8.1°, P vs. post-correction 16.7±9.2°, P=0.053). The number of patients with TS after correction was decreased in EG (P=0.194) and significantly increased in LG (P=0.028). There were both pre-corrective and post-corrective predictive factors for TS (Pre-corrective: age P Conclusions: The Nuss procedure had some significant effects on the thoracic spinal curvature, with early correction able to reduce TS in patients with PE.
