Computed Tomography Radiostereometric Analysis (CT\u2010RSA) is a method that can be used to determine implant and bone micromovements using low\u2010dose CT scans. This study aimed to evaluate the reliability of the CT\u2010RSA method in measuring the interfragmental mobility in patients who have undergone a correction osteotomy due to a malunited distal radius fracture. Twenty\u2010four patients were included and operated with a radiolucent volar plate. Markers were embedded in the plate and bone. RSA and CT examinations were obtained postoperatively up to 1\u2010year postoperative. Micromovements of the distal radius segment relative to the proximal were compared between the methods with paired analysis and Bland\u2013Altman plots. The limits of clinical significance were: dorsal\/volar tilt &lt;\u200910\u00b0, radial shortening &lt;\u20095\u2009mm, radial inclination \u2265\u200915\u00b0, and radial shift &lt;\u20095\u2009mm. For the dorsal\/volar tilt, the paired analysis between the two methods, showed a mean difference (95% CI) of \u22120.06\u00b0 (\u22120.67 to 0.55), for radial compression\u20100.04\u2009mm (\u22120.09 to 0.01), for radial inclination 0.21\u00b0 (\u22120.06 to 0.48), and for radial shift \u22120.07\u2009mm (\u22120.21 to 0.07). The paired analysis for micromotions showed that the thresholds of clinical significance are excluded from the difference's 95% CI. The Bland\u2013Altman plots showed comparable results up to 1 year, considering clinically relevant thresholds. In conclusion, the CT\u2010RSA method is comparable to that of marker\u2010based RSA in measuring micromotions after wrist osteotomy, as the differences between the methods are not clinically significant.<\/jats:p>","DOI":"10.1002\/jor.26031","type":"journal-article","created":{"date-parts":[[2024,12,28]],"date-time":"2024-12-28T06:08:32Z","timestamp":1735366112000},"page":"660-670","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of Marker\u2010Based RSA and CT\u2010RSA for Analyzing Micromotions After Distal Radius Osteotomy: A 1\u2010Year Retrospective Study of 24 Patients"],"prefix":"10.1002","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9207-221X","authenticated-orcid":false,"given":"Vasileios","family":"Angelomenos","sequence":"first","affiliation":[{"name":"Department of Orthopedics, Institute of Clinical Sciences, Sahlgrenska Academy University of Gothenburg Gothenburg Sweden"},{"name":"Department of Hand Surgery Sahlgrenska University Hospital Gothenburg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5825-1692","authenticated-orcid":false,"given":"Olof","family":"Sandberg","sequence":"additional","affiliation":[{"name":"Sectra Link\u00f6ping Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7872-8654","authenticated-orcid":false,"given":"Bita","family":"Shareghi","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Institute of Clinical Sciences, Sahlgrenska Academy University of Gothenburg Gothenburg Sweden"},{"name":"Department of Orthopedics Sahlgrenska University Hospital Gothenburg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Ullman","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Institute of Clinical Sciences, Sahlgrenska Academy University of Gothenburg Gothenburg Sweden"},{"name":"Department of Orthopedics Sahlgrenska University Hospital Gothenburg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,27]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2474-11-282\/FIGURES\/2"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453678909154184"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453674.2012.745352"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0039-1698452"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2006.07.004"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/000164701753606707"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/BOT.0b013e3181839669"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1186\/S40634-021-00329-Y\/FIGURES\/7"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193420934689"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1080\/17453670510041574"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193409355627"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1080\/17453670710014095"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2004.09.018"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/JOR.24063"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/5909741"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/3681458"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s13319-019-0217-z"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1080\/17453674.2021.1906082\/SUPPL_FILE\/IORT_A_1906082_SM2295.PDF"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.2340\/17453674.2022.2528"},{"key":"e_1_2_9_21_1","unstructured":"\u201cISO 16087:2013(en) Implants for Surgery\u2014Roentgen Stereophotogrammetric Analysis for the Assessment of Migration of Orthopaedic Implants \u201d accessed April 17 2023 https:\/\/www.iso.org\/obp\/ui\/#iso:std:iso:16087:ed-1:v1:en."},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1080\/17453670510041574"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1080\/000164700317393420"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1186\/s41747-021-00209-1"},{"key":"e_1_2_9_25_1","unstructured":"D.HartandB.
