Meanwhile, the spinal flexibility evaluated by the fulcrum-bending method may provide a more accurate prediction of post-surgical correction compared to the side-bending approach, particularly for main curves. For the bracing treatment, only a few studies have preliminarily reported good capability of the side-bending method in predicting the initial in-brace correction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This review quantitatively assessed the clinical application ratio and effectiveness of side-bending and fulcrum-bending radiographs in predicting post-intervention curve corrections in AIS patients undergoing surgical or bracing treatments. The results of the current review supported to adopt the fulcrum-bending approach for AIS patients undergoing PSF surgery with main thoracic curves, and the side-bending approach for those with thoracolumbar\/lumbar curves. For patients receiving bracing treatment, further research is still needed to confirm the clinical value of the side-bending method.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/21925682251319543","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T00:55:38Z","timestamp":1740099338000},"page":"2822-2838","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Predicting Surgical and Non-surgical Curvature Correction by Radiographic Spinal Flexibility Assessments for Patients With Adolescent Idiopathic Scoliosis: A Systematic Review and Meta-Analysis"],"prefix":"10.1177","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-5544-7101","authenticated-orcid":false,"given":"Yu-Yan","family":"Luo","sequence":"first","affiliation":[{"name":"The Hong Kong Polytechnic University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tim-Mei","family":"Hung","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Zheng","sequence":"additional","affiliation":[{"name":"Huazhong University of Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui-Dong","family":"Wu","sequence":"additional","affiliation":[{"name":"Kunming Medical University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Man-Sang","family":"Wong","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zi-Qian","family":"Bai","sequence":"additional","affiliation":[{"name":"Southern University of Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6507-2329","authenticated-orcid":false,"given":"Christina Zong-Hao","family":"Ma","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University"},{"name":"The Hong Kong Polytechnic University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,2,20]]},"reference":[{"key":"e_1_3_4_2_2","first-page":"529","article-title":"Adolescent idiopathic scoliosis: etiology, anatomy, natural history, and bracing","volume":"54","author":"Parent S","year":"2005","unstructured":"Parent S, Newton PO, Wenger DR.
