A 3-D statistical shape model of the lunate was built using the computed tomography scans of 54 lunate pairs and shape symmetry was evaluated based on an intraclass correlation analysis. The lunate shape was not bilaterally symmetrical in (1) the angle scaphoid surface \u2013 radius-ulna surface, (2) the dorsal side and the length of the side adjacent to the triquetrum, (3) the orientation of the volar surface, (4) the width of the side adjacent to the scaphoid, (5) the skewness in the coronal plane and (6) the curvature of bone articulating with the hamate and capitate. These findings suggest that using the contralateral lunate to design patient-specific lunate implants may not be as accurate as it is intended.<\/jats:p>","DOI":"10.1177\/17531934211004080","type":"journal-article","created":{"date-parts":[[2021,3,31]],"date-time":"2021-03-31T00:49:51Z","timestamp":1617151791000},"page":"587-593","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["The three-dimensional shape symmetry of the lunate and its implications"],"prefix":"10.1177","volume":"46","author":[{"given":"Nazl\u0131","family":"T\u00fcmer","sequence":"first","affiliation":[{"name":"Department of Biomechanical Engineering, Delft University of Technology (TU Delft), Delft, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olivier","family":"Hiemstra","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Reinier Haga Orthopaedic Centre, Zoetermeer, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yvonne","family":"Schreurs","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Reinier Haga Orthopaedic Centre, Zoetermeer, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerald A.","family":"Kraan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Reinier Haga Orthopaedic Centre, Zoetermeer, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johan","family":"van der Stok","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Reinier Haga Orthopaedic Centre, Zoetermeer, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amir A.","family":"Zadpoor","sequence":"additional","affiliation":[{"name":"Department of Biomechanical Engineering, Delft University of Technology (TU Delft), Delft, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,3,30]]},"reference":[{"key":"bibr1-17531934211004080","unstructured":"Antuna Zapico JM.\n                      Malacia Del Semilunar.\n                      Valladolid, Universidad de Valladolid, 1966."},{"key":"bibr2-17531934211004080","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2014.09.019"},{"key":"bibr3-17531934211004080","doi-asserted-by":"publisher","DOI":"10.3109\/02844318509074518"},{"key":"bibr4-17531934211004080","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2007.03.012"},{"key":"bibr5-17531934211004080","doi-asserted-by":"publisher","DOI":"10.1007\/s11552-014-9624-z"},{"key":"bibr6-17531934211004080","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1097\/00003086-198006000-00003","volume":"149","author":"Kauer JM","year":"1980","journal-title":"Clin Orthop Relat Res"},{"key":"bibr7-17531934211004080","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcm.2016.02.012"},{"key":"bibr8-17531934211004080","doi-asserted-by":"crossref","unstructured":"Lichtman DM, Bain GI.\n                      Kienb\u00f6ck\u2019s disease.
