Under axial loading (60 N; cyclic 60\u2013200 N) and wrist motion, the SL gap and carpal angles, and a CT-derived dorsal instability scaphoid angle (DISA) were measured.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Phase 1 produced no significant instability. Dorsal SLIOL sectioning (phase 2) initiated dynamic instability, with increased SL gap and angles under load and dorsal scaphoid translation, but no resting dorsal intercalated segment instability (DISI). Sectioning the superficial DICL fascicle (phase 3) did not add instability. DSTL sectioning (phase 4) produced the largest changes, with marked SL diastasis, increased angles and DISA, and DISI at rest and under load.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Dorsal SLIOL sectioning produced load-dependent (dynamic) SL instability, whereas subsequent DSTL sectioning was associated with progression to static instability, supporting the DSTL as an important dorsal restraint. The DISA may provide an additional CT-based measure of dorsal scaphoid subluxation; however, clinical validation is required.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17531934261432885","type":"journal-article","created":{"date-parts":[[2026,3,21]],"date-time":"2026-03-21T09:49:16Z","timestamp":1774086556000},"page":"1258-1265","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["The role of the dorsal scaphotriquetral ligament: a biomechanical study"],"prefix":"10.1177","volume":"51","author":[{"given":"Gustavo L Gomez","family":"Rodriguez","sequence":"first","affiliation":[{"name":"Department of Hand Surgery, Climba Clinic, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alvaro","family":"Muratore","sequence":"additional","affiliation":[{"name":"Department of Hand Surgery, Buenos Aires British Hospital, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahlam","family":"Arnaout","sequence":"additional","affiliation":[{"name":"International Wrist Centers \u2013 Institut de la main, Clinique Bizet, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro J","family":"Delgado","sequence":"additional","affiliation":[{"name":"Madrid Monteprincipe University Hospital, San Pablo CEU University, Boadilla del Monte, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory","family":"Bain","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Flinders Medical Centre and Flinders University, South Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanjeev","family":"Kakar","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Mayo Clinic, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,3,21]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(96)80096-7"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200102000-00006"},{"key":"e_1_3_2_4_1","unstructured":"Beutel BG Konstanty J Beeker RW Rehman UH.
