A total of 45 patients who were treated for scaphoid fracture nonunion were included in the study. The height-to-length ratio of the scaphoid was measured on computed tomographic images and used to assess scaphoid deformity. Carpal malalignment was quantified based on the radio-lunate angle. A correlation analysis between the height-to-length ratio and the radio-lunate angle was performed. Dorsal intercalated segmental instability was defined as a radio-lunate angle &gt;15\u00b0, and a receiver operating curve analysis was used to calculate the cutoff height-to-length ratio that can be accompanied with dorsal intercalated segmental instability. Extension of the lunate increases in proportion to the flexion deformity of the scaphoid; dorsal intercalated segmental instability can occur if the height-to-length ratio of the scaphoid is &gt;0.73.<\/jats:p>\n                  <jats:p>\n                    <jats:bold>Level of evidence:<\/jats:bold>\n                    IV\n                  <\/jats:p>","DOI":"10.1177\/1753193416680133","type":"journal-article","created":{"date-parts":[[2016,12,5]],"date-time":"2016-12-05T21:20:25Z","timestamp":1480972825000},"page":"240-245","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Dorsal intercalated segmental instability associated with malunion of a reconstructed scaphoid"],"prefix":"10.1177","volume":"42","author":[{"given":"J.-H.","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Seonam University College of Medicine, Goyang, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.-H.","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Hanyang University College of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.
