Unilateral biportal endoscopy (UBE) offers precise visualization with minimal tissue disruption. However, achieving sufficient biomechanical stability after a major osteotomy, such as hemivertebra (HV) resection, remains critical.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A 7-year-old girl with progressive congenital scoliosis (CS) (segmental Cobb angle 32\u00b0) due to a left L4\/L5 semi-segmented HV underwent complete HV resection via UBE. Using a fully percutaneous technique, the UBE portals were reused for ipsilateral pedicle screw insertion at L4 and L5. Two additional contralateral stab incisions enabled bilateral percutaneous screw placement, followed by rod insertion and compression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The 210-minute procedure achieved a 56% segmental correction (32\u00b0 to 14\u00b0), with estimated blood loss of 100\u2005mL. At 6-month follow-up, correction was maintained (Cobb 14\u00b0) with evidence of radiographic fusion and no complications. The entire procedure required only four stab incisions (each 1\u20131.5\u2005cm).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>UBE enables precise lumbar HV resection under direct visualization. When synergized with bilateral percutaneous short-segment fixation, it provides the mechanical integrity essential for maintaining correction. This combined protocol successfully marries minimal tissue disruption with surgical efficacy, offering a promising alternative within the minimally invasive armamentarium for pediatric spinal deformity.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fped.2026.1773395","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T06:58:30Z","timestamp":1773817110000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Unilateral biportal endoscopic lumbar hemivertebra resection with bilateral percutaneous fixation in a pediatric patient: a case report"],"prefix":"10.3389","volume":"14","author":[{"given":"Peng","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Orthopedics, The 904th Hospital of Joint Logistic Support Force of PLA","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zijie","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The 904th Hospital of Joint Logistic Support Force of PLA","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kun","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The 904th Hospital of Joint Logistic Support Force of PLA","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kefeng","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The 904th Hospital of Joint Logistic Support Force of PLA","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Genyang","family":"Jin","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The 904th Hospital of Joint Logistic Support Force of PLA","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hengyan","family":"Zhuge","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, The 904th Hospital of Joint Logistic Support Force of PLA","place":["Wuxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengyun","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Pediatric Orthopedics, The First Affiliated Hospital of Xiamen University","place":["Xiamen, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Pediatric Orthopedics, The First Affiliated Hospital of Xiamen University","place":["Xiamen, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"194","DOI":"10.14444\/8188","article-title":"Hemivertebra resection and spinal arthrodesis by single-stage posterior approach in congenital scoliosis and kyphoscoliosis: results at 9.6 years mean follow-up","volume":"16","author":"Crostelli","year":"2022","journal-title":"Int J Spine Surg"},{"key":"B2","doi-asserted-by":"publisher","first-page":"110","DOI":"10.1097\/00007632-200201010-00026","article-title":"Single-Stage excision of hemivertebrae via the posterior approach alone for congenital spine deformity: follow-up period Longer than ten years","volume":"27","author":"Nakamura","year":"2002","journal-title":"Spine"},{"key":"B3","doi-asserted-by":"publisher","first-page":"824","DOI":"10.1186\/s12891-024-07931-y","article-title":"Long-Term results of single-stage posterior hemivertebra resection and short segment fusion using pedicle screws fixation in thoracolumbar congenital early-onset scoliosis: an 8.97-year average follow-up study","volume":"25","author":"Peng","year":"2024","journal-title":"BMC Musculoskelet Disord"},{"key":"B4","doi-asserted-by":"publisher","first-page":"100225","DOI":"10.1016\/j.xnsj.2023.100225","article-title":"Unilateral biportal endoscopic supralaminar, posterior spinous process sparing approach for en bloc cervical laminectomy in case of cervical osteochondroma causing myelopathy: a case report","volume":"14","author":"Hung","year":"2023","journal-title":"N Am Spine Soc J"},{"key":"B5","doi-asserted-by":"publisher","first-page":"19","DOI":"10.14444\/8690","article-title":"Clinical outcomes following treatment of cervical spondylotic radiculopathy with cervical posterior decompression using unilateral biportal endoscopic technique: a single center retrospective series of 20 patients","volume":"19","author":"Akbari","year":"2024","journal-title":"Int J Spine Surg"},{"key":"B6","doi-asserted-by":"publisher","first-page":"150","DOI":"10.1016\/j.jor.2024.03.037","article-title":"Unilateral biportal endoscopic surgical decompression for symptomatic ossification of the ligamentum flavum - is it enough to improve the clinical outcome?
