The transverse diameter was measured on plain X-rays. 3D radius models were reconstructed from CT data. A 3D image of polyaxial VLP was used to investigate the most distal plate position at three different screw insertion angles. The linear distance between the volar articular edge and the plate edge was measured and compared among different screw insertion angles. The correlations between the plate positions and the transverse diameter were also evaluated. In addition, the relationship between the most distal screw place and articular surface was confirmed with one case of distal radius fracture.<\/jats:p><jats:p>\n          Results\u2003The optimal positions relative to the neutral were 2.7\u2009mm proximal in the distal swing and 1.9\u2009mm distal in the proximal swing. The linear distance was significantly correlated with the transverse diameter in each group. It was confirmed that the relationship between the most distal screw place and articular surface was applicable in the actual case.<\/jats:p><jats:p>\n          Conclusion\u2003The results showed that the most distal position of the polyaxial VLP differed depending on the screw insertion angle and became more proximal as the transverse diameter increased. These results may be useful as a reference for preoperative planning.<\/jats:p><jats:p>\n          Levels of Evidence\u2003III.<\/jats:p>","DOI":"10.1055\/s-0044-1782238","type":"journal-article","created":{"date-parts":[[2024,3,8]],"date-time":"2024-03-08T23:50:12Z","timestamp":1709941812000},"page":"484-491","source":"Crossref","is-referenced-by-count":4,"title":["Three-Dimensional Analysis of Polyaxial Volar Locking Plate Position for Distal Radius Fracture"],"prefix":"10.1055","volume":"13","author":[{"given":"Yusuke","family":"Eda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tsukuba Medical Center, Tsukuba, Ibaraki, Japan"},{"name":"Department of Orthopaedic Surgery, Tokyo Medical University Ibaraki Medical Center, Inashiki, Ibaraki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sho","family":"Kohyama","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Kikkoman General Hospital, Noda, Chiba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Ikumi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Institute of Medicine, University of Tsukuba, Tsukuba, Ibaraki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoo","family":"Ishii","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tokyo Medical University Ibaraki Medical Center, Inashiki, Ibaraki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masashi","family":"Yamazaki","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Institute of Medicine, University of Tsukuba, Tsukuba, Ibaraki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuichi","family":"Yoshii","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tokyo Medical University Ibaraki Medical Center, Inashiki, Ibaraki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2024,3,8]]},"reference":[{"issue":"08","key":"ref1","doi-asserted-by":"crossref","first-page":"637","DOI":"10.1016\/j.clinbiomech.2009.06.004","article-title":"The strength of polyaxial locking interfaces of distal radius plates","volume":"24","author":"K L Hoffmeier","year":"2009","journal-title":"Clin Biomech (Bristol, Avon)"},{"issue":"11","key":"ref2","doi-asserted-by":"crossref","first-page":"1248","DOI":"10.1016\/j.injury.2010.12.005","article-title":"Evaluation of a polyaxial angle-stable volar plate in a distal radius C-fracture model\u2013a biomechanical study","volume":"42","author":"S Rausch","year":"2011","journal-title":"Injury"},{"issue":"06","key":"ref3","doi-asserted-by":"crossref","first-page":"623","DOI":"10.1097\/SAP.0000000000000850","article-title":"Complication rate comparing variable angle distal locking plate to fixed angle plate fixation of distal radius fractures","volume":"77","author":"R Mehrzad","year":"2016","journal-title":"Ann Plast Surg"},{"issue":"10","key":"ref4","doi-asserted-by":"crossref","first-page":"1720","DOI":"10.1016\/j.jhsa.2008.07.021","article-title":"Fluoroscopic evaluation of intra-articular screw placement during locked volar plating of the distal radius: a cadaveric study","volume":"33","author":"M Soong","year":"2008","journal-title":"J Hand Surg Am"},{"issue":"06","key":"ref5","doi-asserted-by":"crossref","first-page":"953","DOI":"10.1002\/jor.23125","article-title":"Interindividual anatomical variations affect the plate-to-bone fit during osteosynthesis of distal radius fractures","volume":"34","author":"H Yoneda","year":"2016","journal-title":"J Orthop Res"},{"key":"ref6","first-page":"8963768","article-title":"Morphological study of the anterior surface of the distal radius","volume":"2017","author":"H J Cho","year":"2017","journal-title":"BioMed Res Int"},{"issue":"01","key":"ref7","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1007\/s00402-014-2112-7","article-title":"Distal radius: anatomical morphometric gender characteristics.
