Patient\u2010specific instrumentation (PSI) has been introduced to improve reconstruction accuracy, but quantitative comparisons with conventional free\u2010hand techniques remain limited. We retrospectively analyzed 115 scaphoid reconstructions performed between 2010 and 2019; 89 cases met inclusion criteria (45 PSI, 44 conventional). Distal\u2010fragment rotation (flexion\/extension, ulnar\/radial inclination, pronation\/supination) and translation were quantified using a Cartesian coordinate system centered on the proximal pole. A composite 3D deformity angle was calculated to assess global malalignment. PSI achieved greater absolute correction across several parameters. Sagittal flexion improved by 8.9\u00b0 with PSI versus 5.8\u00b0 with conventional reconstruction (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.007 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.043, respectively). Ulnar inclination improved by 3\u00b0 with PSI (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.017) but not significantly with the conventional technique. The composite 3D deformity angle decreased by 8.4\u00b0 with PSI and 6.9\u00b0 conventionally. Despite a longer preoperative non\u2010union duration in the PSI group, consolidation rates (91% vs 93%) and mean times to union were comparable between techniques. Vascularized grafts showed shorter, but non\u2010significant, consolidation times. Both techniques effectively corrected scaphoid deformity. PSI enabled larger morphological corrections in cases with more severe baseline deformity. These findings suggest that PSI may facilitate correction in complex or long\u2010standing non\u2010unions; however, the clinical relevance of the observed 3D differences and operative efficiency remain to be determined.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jor.70220","type":"journal-article","created":{"date-parts":[[2026,5,4]],"date-time":"2026-05-04T05:21:15Z","timestamp":1777872075000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["3D\u2010Printed Patient\u2010Specific Guides Versus Conventional Techniques for Scaphoid Reconstruction: A Comparative Study of 89 Cases"],"prefix":"10.1002","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4844-5351","authenticated-orcid":false,"given":"Sylvano","family":"Mania","sequence":"first","affiliation":[{"name":"Orthopaedic Department, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauro","family":"Maniglio","sequence":"additional","affiliation":[{"name":"Orthopaedic Department, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Wirth","sequence":"additional","affiliation":[{"name":"Orthopaedic Department, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ladislav","family":"Nagy","sequence":"additional","affiliation":[{"name":"Orthopaedic Department, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Reissner","sequence":"additional","affiliation":[{"name":"Orthopaedic Department, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Schweizer","sequence":"additional","affiliation":[{"name":"Orthopaedic Department, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,3]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hansur.2024.101755"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0363-5023(89)90191-3"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/1558944716643295"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2014.09.026"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(98)80093-2"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2005.03.001"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2012.02.020"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2020.01.009"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1142\/S2424835521500387"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193419866598"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0039-1693658"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681_90_90041-2"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(84)80025-8"},{"key":"e_1_2_10_15_1","first-page":"759","article-title":"Fracture of the Carpal Navicular: Diagnosis, Non\u2010Operative Treatment, and Operative Treatment","volume":"42","author":"Russe O.","year":"1960","journal-title":"Journal of Bone & Joint Surgery"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2015.10.009"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm14062082"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193416641590"},{"key":"e_1_2_10_19_1","first-page":"203","article-title":"Vascularized Bone Graft Pedicled on the Volar Carpal Artery for Non\u2010Union of the Scaphoid","volume":"12","author":"Kuhlmann J.
