Malunion of phalangeal fractures usually manifests as a combination of rotational deformities in the coronal, sagittal, and transverse planes, and corrective osteotomy is performed on the planes that cause these problems. Quantification of the deformity is essential for precise osteotomy and is difficult to perform in the transverse plane, even with radiography or computed tomography. Thus, we developed a technique called linkage simulation for the quantitative measurement of rotational deformities for surgical planning. In this procedure, finger extension and flexion can be simulated based on the predicted rotational axis of the joint, which is useful for determining the appropriate correction. Furthermore, by performing a reduction simulation in the software, it is possible to simulate the surgery and predict the postoperative results. This paper reports the details of this technique.<\/jats:p>","DOI":"10.3390\/diagnostics14161818","type":"journal-article","created":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T03:07:38Z","timestamp":1724296058000},"page":"1818","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Quantitative Measurement of Rotation in Phalangeal Fracture Malunion Using Computed Tomography Imaging\u2014\u201cLinkage Simulation\u201d"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8444-4941","authenticated-orcid":false,"given":"Hidemasa","family":"Yoneda","sequence":"first","affiliation":[{"name":"Department of Human Enhancement and Hand Surgery, Nagoya University, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8560, Japan"},{"name":"Department of Limb Traumatology, Nagoya University, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8560, Japan"},{"name":"Department of Orthopedics, Aichi Medical University, 1-1 Yazakokarimata, Nagakute 480-1195, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsuyuki","family":"Iwatsuki","sequence":"additional","affiliation":[{"name":"Department of Human Enhancement and Hand Surgery, Nagoya University, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaomi","family":"Saeki","sequence":"additional","affiliation":[{"name":"Department of Human Enhancement and Hand Surgery, Nagoya University, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsuhiko","family":"Murayama","sequence":"additional","affiliation":[{"name":"Department of Limb Traumatology, Nagoya University, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6937-3567","authenticated-orcid":false,"given":"Nobunori","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Aichi Medical University, 1-1 Yazakokarimata, Nagakute 480-1195, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michiro","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Human Enhancement and Hand Surgery, Nagoya University, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitoshi","family":"Hirata","sequence":"additional","affiliation":[{"name":"Department of Human Enhancement and Hand Surgery, Nagoya University, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8560, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1016\/S0266-7681(96)80009-X","article-title":"Corrective osteotomy for post-traumatic malunion of the phalanges in the hand","volume":"21","author":"Buchler","year":"1996","journal-title":"J.
