Segmented HV-associated scoliosis presents significant surgical challenges, requiring meticulous planning and precise execution for optimal outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>A 12-year-old female presented with severe lumbar scoliosis (75\u00b0 focal curve) due to a fully segmented supernumerary HV at L3\u20134, causing coronal trunk shift, pelvic obliquity, and activity-limiting back pain. A short-segment L1\u20135 posterior instrumented fusion with vertebral column resection was performed using stereotactic navigation for pedicle screw placement and a modular screw system to optimize surgical access. The HV was resected using ultrasonic bone-cutting instruments, osteotomes, and a coarse diamond drill. Deformity correction was achieved through controlled compression and distraction forces with cobalt-chromium rods. Postoperatively, the patient experienced transient radicular pain, which resolved within 4 weeks with conservative management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>This case highlights the challenges of delayed HV detection and the importance of advanced surgical techniques for deformity correction. Stereotactic navigation, modular instrumentation, and careful execution of a hemivertebrectomy facilitated optimal correction while preserving mobility in adjacent spinal regions. A tailored approach is critical for long-term stability and functional outcomes.<\/jats:p>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/thejns.org\/doi\/10.3171\/CASE25244\">https:\/\/thejns.org\/doi\/10.3171\/CASE25244<\/jats:ext-link>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case25244","type":"journal-article","created":{"date-parts":[[2025,7,14]],"date-time":"2025-07-14T06:25:43Z","timestamp":1752474343000},"source":"Crossref","is-referenced-by-count":0,"title":["Technical aspects of performing a hemivertebrectomy for adolescent congenital scoliosis: Illustrative case"],"prefix":"10.3171","volume":"10","author":[{"given":"Aaron","family":"Gelinne","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of North Carolina Hospitals, Chapel Hill, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Allie L.","family":"Harbert","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of North Carolina Hospitals, Chapel Hill, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lauren E.","family":"Corliss","sequence":"additional","affiliation":[{"name":"School of Medicine, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael A.","family":"Galgano","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of North Carolina Hospitals, Chapel Hill, North Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"2","key":"bib1","series-title":"Fetal Diagn Ther","first-page":"121","article-title":"Hemivertebra: prenatal diagnosis, incidence and characteristics","volume":"20","author":"Goldstein","year":"2005","unstructured":"Goldstein IMakhoul IRWeissman ADrugan A.Hemivertebra: prenatal diagnosis, incidence and characteristics.
