A series of 36 AIS immature patients (Risser 3 or less) were included in the study. Instrumentation was removed once the maturity stage was complete (Risser 5). The curve correction was assessed pre- and postoperatively, before instrumentation removal, directly post-removal, and more than two years after instrumentation was removed. Epiphyseal vertebral growth modulation was assessed by the coronal wedging ratio (WR) at the apical level of the main curve (MC). The mean preoperative coronal Cobb was corrected from 53.7\u00b0 \u00b1 7.5 to 5.5\u00b0 \u00b1 7.5\u00b0 (89.7%) at the immediate postop. After implant removal (31.0 \u00b1 5.8 months), the MC was 13.1\u00b0. T5\u2013T12 kyphosis showed significant improvement from 19.0\u00b0 before curve correction to 27.1\u00b0 after implant removal (p &lt; 0.05). Before surgery, the WR was 0.71 \u00b1 0.06, and after removal, 0.98 \u00b1 0.08 (p &lt; 0.001). At the end of the follow-up, the mean sagittal range of motion (ROM) of the T12-S1 segment was 51.2 \u00b1 21.0\u00b0. The SRS-22 scores improved from 3.31 \u00b1 0.25 preoperatively to 3.68 \u00b1 0.25 at the final assessment (p &lt; 0.001). In conclusion, a fusionless posterior approach using common all-pedicle screws correctly constructed satisfactory scoliotic main curves and permitted the removal of instrumentation once bone maturity was reached. The final correction was highly satisfactory, and an acceptable ROM of the previously lower instrumented segments was observed.<\/jats:p>","DOI":"10.3390\/jcm12062408","type":"journal-article","created":{"date-parts":[[2023,3,21]],"date-time":"2023-03-21T02:36:22Z","timestamp":1679366182000},"page":"2408","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Fusionless All-Pedicle Screws for Posterior Deformity Correction in AIS Immature Patients Permit the Restoration of Normal Vertebral Morphology and Removal of the Instrumentation Once Bone Maturity Is Reached"],"prefix":"10.3390","volume":"12","author":[{"given":"Jes\u00fas","family":"Burgos","sequence":"first","affiliation":[{"name":"Spine Unit, Hospital Viamed Fuensanta, 28027 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5166-198X","authenticated-orcid":false,"given":"Gonzalo","family":"Mariscal","sequence":"additional","affiliation":[{"name":"School of Doctorate, Valencia Catholic University, 46001 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis Miguel","family":"Ant\u00f3n-Rodrig\u00e1lvarez","sequence":"additional","affiliation":[{"name":"Pediatric Orthopedics, Ramon y Cajal Hospital, 28034 Madrid, Spain"},{"name":"Pediatric Orthopedics, Hospital Son Espases, 07198 Palma de Mallorca, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ignacio","family":"Sanpera","sequence":"additional","affiliation":[{"name":"Pediatric Orthopedics, Hospital Son Espases, 07198 Palma de Mallorca, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo","family":"Hevia","sequence":"additional","affiliation":[{"name":"Spine Unit, Hopsital La Fraternidad-Muprespa, 28036 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vicente","family":"Garc\u00eda","sequence":"additional","affiliation":[{"name":"Secci\u00f3n de Cirug\u00eda de Columna, Hospital Universitario Araba, 01009 Vitoria, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6657-7246","authenticated-orcid":false,"given":"Carlos","family":"Barrios","sequence":"additional","affiliation":[{"name":"Institute for Research on Musculoskeletal Disorders, Valencia Catholic University, 46001 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,21]]},"reference":[{"key":"ref_1","first-page":"335","article-title":"Surgical aspects of spinal growth modulation in scoliosis correction","volume":"63","author":"Jain","year":"2014","journal-title":"Instr.
