The algorithm involved alignment, landmark detection, initial placement, and final optimization. Retrospective data of 34 planned radii and corresponding plate positions, including decimated and refined mesh versions, were used to compare algorithm output to manual placement based on runtime, Hausdorff distance, translation, and rotation (mean\u2009\u00b1\u2009SD, 95% CI), thereby assessing robustness across different mesh resolutions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The average run time for the algorithm was 18.3\u2009\u00b1\u200916.8 s (95% CI 12.4\u201324.1 s) compared to a manual placement time of 12.45\u2009\u00b1\u20094.56 min (single expert,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200910, 95% CI 9.22\u201316.28 min).
