In progressive cases of NF-1-associated cervical deformity, surgical intervention may be required to prevent further deterioration. However, there remain no generally recognized guidelines on the surgical strategy for NF-1-related cervical deformity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>A 39-year-old man with diagnosed NF-1 was airlifted to our hospital due to neck pain and bilateral upper extremity paralysis. X-rays and computed tomography (CT) revealed severe neck deformity, including anterior displacement of the C5 vertebral body. We performed laminectomy (C4-C6), posterior fixation (C2-T2), and autologous bone grafting using a pedicle screw construct with cobalt-chromium rods in addition to accessory rods for reinforcement. No surgery-related adverse events were recorded. Successful bone fusion was confirmed by X-rays and CT 2\u00a0years postoperatively, with no noticeable correction loss.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In the reported case of severe cervical deformity attributed to NF-1, posterior spinal fusion using a multi-rod construct achieved favorable outcomes and may be considered a viable treatment option.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s43390-026-01430-x","type":"journal-article","created":{"date-parts":[[2026,5,20]],"date-time":"2026-05-20T15:35:28Z","timestamp":1779291328000},"page":"2327-2331","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Severe cervical deformity due to neurofibromatosis type 1 treated by posterior spinal fusion using a multi-rod construct: a case report"],"prefix":"10.1007","volume":"14","author":[{"given":"Shota","family":"Shimizu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0718-6357","authenticated-orcid":false,"given":"Masashi","family":"Uehara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shota","family":"Ikegami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshinari","family":"Miyaoka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroki","family":"Oba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisuke","family":"Kurogochi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takuma","family":"Fukuzawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinji","family":"Sasao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Takahashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,5,20]]},"reference":[{"key":"1430_CR1","doi-asserted-by":"publisher","first-page":"692","DOI":"10.2106\/00004623-199405000-00010","volume":"76","author":"H Funasaki","year":"1994","unstructured":"Funasaki H, Winter RB, Lonstein JB, Denis F (1994) Pathophysiology of spinal deformities in neurofibromatosis.
