Propensity score matching included age, sex, ASA physical status, anatomical region, surgical indication, and surgeon expertise. Surgeons were stratified according to prior spondylodesis case volume. Outcomes included screw revision rates (as a measure of screw accuracy), screw placement time, operative time, blood loss, and perioperative complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Unadjusted screw-level revision proportions were 2.3% with robotic assistance and 3.5% with navigation-guided instrumentation. In adjusted patient-level analysis, greater surgeon experience, but not robotic assistance, was associated with fewer revisions. In the lowest-experience group, the proportions were descriptively 4.3% and 8.2%, but the technique-by-experience interaction was not statistically significant. Median screw-placement time was longer with robotic assistance (7.8 vs. 5.5\u00a0min per screw,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).

The observed increase in screw placement time may reflect the early adaptation phase of the robotic technique rather than an inherent limitation of the system. The descriptive reduction in revision rates among less experienced surgeons suggests a potential role for robotic assistance in supporting standardization and surgical training; however, this exploratory finding warrants confirmation in larger studies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00586-026-10421-5","type":"journal-article","created":{"date-parts":[[2026,10,20]],"date-time":"2026-10-20T06:16:13Z","timestamp":1792476973000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Impact of surgeon experience on the safety and accuracy of robot-assisted vs. navigation-guided percutaneous pedicle screw placement: a matched cohort study"],"prefix":"10.1007","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0037-1096","authenticated-orcid":false,"given":"Paul","family":"Backhaus","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8148-1033","authenticated-orcid":false,"given":"Carolin","family":"Albrecht","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2282-8744","authenticated-orcid":false,"given":"Luisa Mona","family":"Kraus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp","family":"Karschnia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Negwer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6486-7955","authenticated-orcid":false,"given":"Bernhard","family":"Meyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arthur","family":"Wagner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,10,20]]},"reference":[{"issue":"1","key":"10421_CR1","doi-asserted-by":"publisher","first-page":"9","DOI":"10.21037\/jss-21-102","volume":"8","author":"NJ Lee","year":"2022","unstructured":"Lee NJ et al (2022) A multicenter study of the 5-year trends in robot-assisted spine surgery outcomes and complications.
