Robot\u2010assisted techniques may provide a stable and effective minimally invasive approach for the treatment of lumbar spondylolysis. To compare the clinical efficacy between robot\u2010assisted percutaneous screw fixation combined with endoscopic bone graft and conventional open screw fixation with bone graft in the treatment of lumbar spondylolysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cohort study involving 43 individuals with lumbar spondylolysis who underwent surgical treatment was conducted. From January 2022 to June 2023, 20 patients underwent percutaneous screw fixation combined with endoscopic bone graft while 23 patients underwent conventional open screw fixation with bone graft. The demographic data, parameters related to robotic surgery, perioperative indicators, VAS and ODI scores, pedicle screw accuracy, radiographic fusion outcomes, and follow\u2010up results were systematically recorded, analyzed, and then compared between the two groups. Categorical variables were analyzed using chi\u2010square tests, and continuous variables were evaluated with t\u2010tests or Mann\u2013Whitney <jats:italic>U<\/jats:italic> tests following normality assessment, with statistical significance at <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared with the conventional surgery group, the robot\u2010assisted surgery group had significantly less intraoperative blood loss, less postoperative drainage, shorter hospital stay, less intraoperative fluoroscopy times, and radiation exposure dose (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Nevertheless, the duration of the surgery was longer. Postoperative imaging findings showed high screw accuracy in both groups, with a grade A rate of 95% in the robot\u2010assisted group compared with 91.4% in the conventional open surgery group according to the Gertzbein\u2013Robbins scale. Both groups achieved similar improvements in VAS and ODI during 1\u2010year follow\u2010up, and both groups achieved good bone graft fusion (97.5% fusion rate in the robot\u2010assisted group versus 93.5% in the conventional open surgery group).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Robot\u2010assisted screw fixation combined with endoscopic bone graft provides a safe and reliable minimally invasive treatment of lumbar spondylolysis, with high accuracy of pedicle screw implantation and less radiation exposure dose, less intraoperative trauma, and quicker recovery than conventional open surgery.<\/jats:p><\/jats:sec>","DOI":"10.1111\/os.14368","type":"journal-article","created":{"date-parts":[[2025,2,11]],"date-time":"2025-02-11T09:50:27Z","timestamp":1739267427000},"page":"1143-1151","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Robot\u2010Assisted Screw Fixation Combined With Endoscopic Bone Graft in the Minimally Invasive Treatment of Lumbar Spondylolysis: A Single\u2010Center Retrospective Study"],"prefix":"10.1111","volume":"17","author":[{"given":"Guanjie","family":"Zeng","sequence":"first","affiliation":[{"name":"Division of Spine Surgery, Department of Orthopaedics Nanfang Hospital, Southern Medical University  Guangzhou China"},{"name":"Department of Orthopaedics Surgery and Traumatology The University of Hong Kong\u2010Shenzhen Hospital (HKU\u2010SZH)  Shenzhen China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zongze","family":"Li","sequence":"additional","affiliation":[{"name":"Division of Spine Surgery, Department of Orthopaedics Nanfang Hospital, Southern Medical University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juedong","family":"Hou","sequence":"additional","affiliation":[{"name":"Division of Spine Surgery, Department of Orthopaedics Nanfang Hospital, Southern Medical University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liu","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Human Anatomy School of Basic Medical Sciences, Southern Medical University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuhui","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging Center Nanfang Hospital, Southern Medical University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongjian","family":"Zhu","sequence":"additional","affiliation":[{"name":"Division of Spine Surgery, Department of Orthopaedics Nanfang Hospital, Southern Medical University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ling","family":"Yao","sequence":"additional","affiliation":[{"name":"Division of Spine Surgery, Department of Orthopaedics Nanfang Hospital, Southern Medical University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiarui","family":"Chen","sequence":"additional","affiliation":[{"name":"Shenzhen Futurtec Medical Co.
