While accurate, current navigation systems and patient\u2010specific instruments present limitations, including high costs, radiation exposure, workflow disruption, long production time, and lack of reusability. This study evaluates a real\u2010time vision\u2010guided surgical system combined with modular jigs to improve accuracy in pelvic bone tumor resections. A vision\u2010guided surgical system combined with modular cutting jigs and real\u2010time optical tracking was developed and validated. Five male pelvis sawbones were used, with each hemipelvis randomly assigned to either the vision\u2010guided and modular jig system or the traditional freehand method. A total of 20 resection planes were analyzed for each method. Accuracy was assessed by measuring distance and angular deviations from the planned resection planes. The vision\u2010guided and modular jig system significantly improved resection accuracy compared to the freehand method, reducing the mean distance deviation from 2.07\u2009\u00b1\u20091.71\u2009mm to 1.01\u2009\u00b1\u20090.78\u2009mm (<jats:italic>p<\/jats:italic>\u2009=\u20090.0193). In particular, all specimens resected using the vision\u2010guided system exhibited errors of less than 3\u2009mm. Angular deviations also showed significant improvements with roll angle deviation reduced from 15.36\u2009\u00b1\u200917.57\u00b0 to 4.21\u2009\u00b1\u20093.46\u00b0 (<jats:italic>p<\/jats:italic>\u2009=\u20090.0275), and pitch angle deviation decreased from 6.17\u2009\u00b1\u20094.58\u00b0 to 1.84\u2009\u00b1\u20091.48\u00b0 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). The proposed vision\u2010guided and modular jig system significantly improves the accuracy of pelvic bone tumor resections while maintaining workflow efficiency. This cost\u2010effective solution provides real\u2010time guidance without the need for referencing external monitors, potentially improving surgical outcomes in complex pelvic bone tumor cases.<\/jats:p>","DOI":"10.1002\/jor.26111","type":"journal-article","created":{"date-parts":[[2025,5,23]],"date-time":"2025-05-23T07:56:05Z","timestamp":1747986965000},"page":"1485-1492","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Improved Accuracy in Pelvic Tumor Resections Using a Real\u2010Time Vision\u2010Guided Surgical System"],"prefix":"10.1002","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-9235-3472","authenticated-orcid":false,"given":"Vahid","family":"Danesh","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering Stony Brook University Stony Brook New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Arauz","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Renaissance School of Medicine Stony Brook University Stony Brook New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maede","family":"Boroji","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Stony Brook University Stony Brook New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Renaissance School of Medicine Stony Brook University Stony Brook New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mia","family":"Cottone","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Stony Brook University Stony Brook New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elaine","family":"Gould","sequence":"additional","affiliation":[{"name":"Department of Radiology, Renaissance School of Medicine Stony Brook University Stony Brook New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fazel A.","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Renaissance School of Medicine Stony Brook University Stony Brook New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Imin","family":"Kao","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Stony Brook University Stony Brook New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,23]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-008-0495-x"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2003.01.142"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s002470050743"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-001-0471-y"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-012-2529-7"},{"key":"e_1_2_10_7_1","first-page":"1","article-title":"Principles of Tumor Management","volume":"33","author":"Springfield D.
