Respiratory impairment differs by etiology, with non-idiopathic scoliosis often showing more severe and persistent deformity. Conventional pulmonary function testing provides global functional assessment but is frequently limited in patients with non-idiopathic scoliosis. Advances in chest computed tomography (CT) allow quantitative evaluation of lung volume and airway morphology, offering an alternative approach to assess respiratory function and the relationship to spinal deformity.<\/jats:p>\n                  <jats:p>AIM<\/jats:p>\n                  <jats:p>To investigate CT-derived airway morphology and respiratory function in thoracic scoliosis, focusing on etiologic differences and structure-function relationships.<\/jats:p>\n                  <jats:p>METHODS<\/jats:p>\n                  <jats:p>This retrospective observational study included 53 patients \u2264 30 years of age who underwent corrective surgery for thoracic scoliosis and had preoperative and postoperative CT examinations. Patients were classified into idiopathic (n  = 25) or non-idiopathic scoliosis (n  = 28). Spinal deformity parameters, lung volumes, predicted total lung capacity percentage (TLC%), and airway dimensions were quantified using CT. Group comparisons were performed using the Wilcoxon rank-sum test, correlations were determined using Spearman\u2019s rank correlation, and pre- and postoperative changes were determined using the Wilcoxon signed-rank test.<\/jats:p>\n                  <jats:p>RESULTS<\/jats:p>\n                  <jats:p>Patients with non-idiopathic scoliosis had significantly more severe spinal deformities and a lower TLC% compared to patients with idiopathic scoliosis (median TLC%: 39% vs  64%, P  &lt; 0.001). The Cobb angle was negatively correlated with TLC% (\u03c1  = -0.52, P  = 0.004), lung volumes, and multiple airway parameters in patients with non-idiopathic scoliosis. Surgical correction significantly improved spinal alignment in both groups. CT-derived lung volume parameters did not show significant postoperative changes. In contrast, selective improvement was observed in the left bronchus.<\/jats:p>\n                  <jats:p>CONCLUSION<\/jats:p>\n                  <jats:p>CT-derived analysis showed differences in respiratory impairment between idiopathic and non-idiopathic scoliosis. Surgical correction improved alignment without immediate lung volume improvement, with selective changes in the left bronchus.<\/jats:p>","DOI":"10.4329\/wjr.119975","type":"journal-article","created":{"date-parts":[[2026,6,2]],"date-time":"2026-06-02T15:38:15Z","timestamp":1780414695000},"source":"Crossref","is-referenced-by-count":0,"title":["Computed tomography-derived assessment of respiratory impairment in thoracic scoliosis: Comparison between idiopathic and non-idiopathic etiologies"],"prefix":"10.4329","volume":"18","author":[{"given":"Nanae","family":"Tsuchiya","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoko","family":"Yogi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akira","family":"Yogi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gyo","family":"Iida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koji","family":"Yonemoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takanao","family":"Shimabukuro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kotaro","family":"Nishida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akihiro","family":"Nishie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2060","published-online":{"date-parts":[[2026,6,28]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prrv.2006.04.009"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2009.08.451"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-022-07371-z"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1007\/BF00301051"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.67B5.4055863"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181714536"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1007\/s00776-011-0028-4"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1001\/jama.289.5.559"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00025509"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.11622\/smedj.2016009"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2021.12.011"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/640573"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.21037\/jss.2018.12.14"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-007-0488-6"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-020-06383-x"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1148\/rg.2018170102"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.00289-2020"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.05.00035205"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-014-3327-6"},{"key":"B20","doi-asserted-by":"publisher","DOI":"10.4103\/0019-5413.136223"},{"key":"B21","doi-asserted-by":"publisher","DOI":"10.1186\/s13018-025-06649-4"},{"key":"B22","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.01499-2021"}],"container-title":["World Journal of Radiology"],"original-title":[],"link":[{"URL":"https:\/\/www.wjgnet.com\/1949-8470\/full\/v18\/i6\/119975.htm","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.wjgnet.com\/1949-8470\/full\/v18\/i6\/119975.htm","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,25]],"date-time":"2026-06-25T01:51:06Z","timestamp":1782352266000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.wjgnet.com\/1949-8470\/full\/v18\/i6\/119975.htm"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,28]]},"references-count":22,"journal-issue":{"issue":"6"},"alternative-id":["119975"],"URL":"https:\/\/doi.org\/10.4329\/wjr.119975","relation":{},"ISSN":["1949-8470"],"issn-type":[{"value":"1949-8470","type":"print"}],"subject":[],"published":{"date-parts":[[2026,6,28]]}}}
