While AR-assisted pedicle and S2 alar-iliac screw placement has been reported, AR guidance for a dual-iliac quad-rod construct in spinopelvic dissociation has not. We describe AR-assisted minimally invasive placement of L4\u2013L5 pedicle screws and bilateral iliac screws using intraoperative three-dimensional planning. Fixation was completed without complications and remained stable at last follow-up. This case suggests AR navigation may support accurate and efficient execution of complex minimally invasive spinopelvic fixation.<\/jats:p>","DOI":"10.1007\/s00701-026-06818-2","type":"journal-article","created":{"date-parts":[[2026,3,6]],"date-time":"2026-03-06T21:02:06Z","timestamp":1772830926000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Augmented-reality-assisted minimally invasive quad-rod spinopelvic fixation for spinopelvic dissociation caused by pathological fracture due to extramedullary plasmacytoma: an evaluation of technique and its benefits"],"prefix":"10.1007","volume":"168","author":[{"given":"Rakesh","family":"Kumar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth T.","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kento","family":"Yamanouchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Venu M.","family":"Nemani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Christophe","family":"Leveque","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip K.","family":"Louie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajiv K.","family":"Sethi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2026,3,6]]},"reference":[{"issue":"1","key":"6818_CR1","doi-asserted-by":"publisher","first-page":"10","DOI":"10.1186\/s13045-017-0549-1","volume":"11","author":"J Caers","year":"2018","unstructured":"Caers J, Paiva B, Zamagni E et al (2018) Diagnosis, treatment, and response assessment in solitary plasmacytoma: updated recommendations from a European expert panel.
