However, the reliability of measurements based directly on the implant (implant\u2010based method) and their agreement with the commonly used bone\u2010based method remain unclear. In this study, CT scans from 29 patients undergoing primary aTSA were used to calculate postoperative glenoid positioning (translations, version, inclination) and HHS in the anterior\u2013posterior (HHS\n                      <jats:sub>AP<\/jats:sub>\n                      ) and superior\u2013inferior (HHS\n                      <jats:sub>SI<\/jats:sub>\n                      ) directions using both methods. The bone\u2010based method referenced measurements to 3D postoperative scapular bone reconstructions, whereas the implant\u2010based method used CT\u2010registered digital glenoid component models. Inter\u2010 and intra\u2010rater reliability of implant\u2010based measurements were assessed using intraclass correlation coefficients (ICCs), and agreement between methods was evaluated using ICCs and Bland\u2013Altman analyses. The implant\u2010based approach demonstrated high inter\u2010 and intra\u2010rater reliability (ICCs\u2009&gt;\u20090.88), with minimal detectable changes below commonly cited clinical thresholds. The agreement between implant\u2010 and bone\u2010based methods was moderate\u2010to\u2010excellent overall (ICC\u2009&gt;\u20090.52), although significant bias and\/or wide limits of agreement were observed for version, inclination, superior\n                      <jats:bold>\u2010<\/jats:bold>\n                      inferior implant positioning, and HHS\n                      <jats:sub>SI<\/jats:sub>\n                      . Compared to implant\u2010based measures, bone\u2010based estimates showed a bias toward more superior implant positioning and superior HHS\n                      <jats:sub>SI<\/jats:sub>\n                      , greater retroversion, and more medialized implant positioning. In conclusion, direct implant\u2010to\u2010CT registration is a reliable method for 3D postoperative measurements after aTSA. Implant\u2010 and bone\u2013based measurements can be used interchangeably for anterior\u2013posterior implant positioning and HHS\n                      <jats:sub>AP<\/jats:sub>\n                      , but not for other measures when high precision is required.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>Basic science study.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jor.70292","type":"journal-article","created":{"date-parts":[[2026,10,10]],"date-time":"2026-10-10T08:43:48Z","timestamp":1791621828000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Reliability of Implant\u2010 vs. Bone\u2010Based Postoperative Measurements After Anatomic Total Shoulder Arthroplasty Using CT Imaging"],"prefix":"10.1002","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3856-1167","authenticated-orcid":false,"given":"Nazanin","family":"Daneshvarhashjin","sequence":"first","affiliation":[{"name":"Department of Development and Regeneration, Faculty of Medicine Institute for Orthopaedic Research and Training (IORT), KU Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Debeer","sequence":"additional","affiliation":[{"name":"Department of Development and Regeneration, Faculty of Medicine Institute for Orthopaedic Research and Training (IORT), KU Leuven Leuven Belgium"},{"name":"Division of Orthopaedics University Hospitals Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0469-6052","authenticated-orcid":false,"given":"Filip","family":"Verhaegen","sequence":"additional","affiliation":[{"name":"Department of Development and Regeneration, Faculty of Medicine Institute for Orthopaedic Research and Training (IORT), KU Leuven Leuven Belgium"},{"name":"Division of Orthopaedics University Hospitals Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1727-533X","authenticated-orcid":false,"given":"Lennart","family":"Scheys","sequence":"additional","affiliation":[{"name":"Department of Development and Regeneration, Faculty of Medicine Institute for Orthopaedic Research and Training (IORT), KU Leuven Leuven Belgium"},{"name":"Division of Orthopaedics University Hospitals Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,10]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2023.10.031"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.16.00935"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2016.03.010"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2021.01.018"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2023.11.010"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.JSE.2026.03.019"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jseint.2023.02.007"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2017.12.012"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm10245773"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.25170"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/S00256-020-03528-3\/METRICS"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1177\/15563316211040829"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2013.01.005"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2015.07.024"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.JSE.2023.12.019"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/J.JSE.2019.04.037"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1371\/JOURNAL.PONE.0201759"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2020.03.007"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1007\/S00256-014-1987-2"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.25747"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.20.00833"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2025.112845"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1007\/S10237-025-01947-6"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2023.05.002"},{"issue":"1","key":"e_1_2_9_26_1","first-page":"231","article-title":"Quantifying Test\u2010Retest Reliability Using the Intraclass Correlation Coefficient and the SEM","volume":"19","author":"Weir J.
