Halo-gravity traction (HGT) is commonly employed preoperatively to enhance spinal flexibility and reduce curve severity. This study aimed to evaluate the effectiveness of HGT in reducing Cobb angles in AIS and to assess how patient age, skeletal maturity (Risser score), and curve type (Lenke classification) influence treatment response. Methods: We conducted a retrospective cohort study of 28 AIS patients with Cobb angles &gt; 65\u00b0 who underwent preoperative HGT followed by posterior spinal fusion. Traction was applied for a mean of 24.64 days, reaching 40\u201350% of each patient\u2019s body weight. Radiographic measurements were collected pre-traction, post-traction, and postoperatively. Statistical analyses included paired t-tests, Pearson correlations, Kruskal\u2013Wallis tests, and linear regression. Results: Mean primary Cobb angle was reduced from 82.46\u00b0 pre-traction to 61.00\u00b0 post-traction (26.09% reduction) and further to 29.54\u00b0 postoperatively (64.58% total reduction). Similar reductions were observed in secondary curves. No statistically significant correlations were found between age or Risser score and the magnitude of correction. Lenke type 3 showed the highest traction response, while type 5 had the greatest surgical gain. Curve type and skeletal maturity did not significantly affect final outcomes. Conclusions: Halo-gravity traction is a safe and effective adjunct in the surgical treatment of severe AIS, achieving substantial Cobb angle reduction. The degree of correction was not significantly influenced by age, Risser score, or curve type, supporting the broad applicability of HGT across adolescent patients.<\/jats:p>","DOI":"10.3390\/children12081045","type":"journal-article","created":{"date-parts":[[2025,8,11]],"date-time":"2025-08-11T08:10:32Z","timestamp":1754899832000},"page":"1045","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Impact of Preoperative Halo Traction on Cobb Angle Reduction in Adolescent Idiopathic Scoliosis: A Retrospective Analysis"],"prefix":"10.3390","volume":"12","author":[{"given":"Mihai Bogdan","family":"Popescu","sequence":"first","affiliation":[{"name":"11th Department of Pediatric Orthopedics, Carol Davila University of Medicine and Pharmacy, Bd.
