Die dorsale Triquetrumabsprengung\n                    ist mit 93% die h\u00e4ufigste Frakturform. F\u00fcr sie werden zwei Unfallmechanismen\n                    diskutiert: einerseits eine Avulsion der am Triquetrum ansetzenden B\u00e4nder,\n                    andererseits die Impaktion durch ein prominentess ulnares Styloid. Typisch ist\n                    ein lokal umschriebener Druckschmerz dorsal \u00fcber dem Triquetrum. Die Diagnose\n                    wird anhand seitlicher Handgelenk-R\u00f6ntgenaufnahmen, bedarfsweise auch mittels\n                    CT, best\u00e4tigt. Die Behandlung erfolgt f\u00fcr rein oss\u00e4re als auch osteoligament\u00e4re\n                    Absprengungen konservativ mit einem Handgelenkgips f\u00fcr 3 Wochen. Mehrmonatige\n                    Restbeschwerden sind dabei nicht ungew\u00f6hnlich und unabh\u00e4ngig von der meist\n                    ausbleibenden Konsolidierung. Korpusfrakturen treten wesentlich seltener auf und\n                    sind mitunter Teil einer h\u00f6hergradigeren Verletzung, wie einer perilun\u00e4ren\n                    Luxationsfraktur. Die R\u00f6ntgendiagnostik wird daher obligat durch ein CT erg\u00e4nzt.\n                    Palmare kortikale Frakturen k\u00f6nnen einer Avulsion des kr\u00e4ftigen palmaren Anteils\n                    des lunotriquetralen (LT) Bandes entsprechen. Die Diagnostik dieser\n                    Verletzungsform erfordert daher neben den Standard-R\u00f6ntgenaufnahmen des\n                    Handgelenkes oft auch ein MRT. Die Arthroskopie best\u00e4tigt die Diagnose der\n                    LT-Bandruptur. An diese kann sich schlie\u00dflich direkt eine Transfixation des\n                    LT-Gelenks anschlie\u00dfen.<\/jats:p>","DOI":"10.1055\/a-2920-8336","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T22:58:41Z","timestamp":1787093921000},"source":"Crossref","is-referenced-by-count":0,"title":["Triquetrumfrakturen \u2013 h\u00e4ufige Ursache posttraumatischer ulnarer\n                    Handgelenkschmerzen"],"prefix":"10.1055","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4802-8016","authenticated-orcid":false,"given":"Steffen","family":"L\u00f6w","sequence":"additional","affiliation":[{"name":"Praxis f\u00fcr Handchirurgie und Unfallchirurgie, Germany","place":["Bad Mergentheim"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Kiesel","sequence":"additional","affiliation":[{"name":"Praxis f\u00fcr Handchirurgie und Unfallchirurgie, Germany","place":["Bad Mergentheim"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian Karl","family":"Spies","sequence":"additional","affiliation":[{"name":"SRO AG, BE, Switzerland","place":["Langenthal"],"department":["Abteilung f\u00fcr Handchirurgie"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Unglaub","sequence":"additional","affiliation":[{"name":"Vulpius Klinik, Germany","place":["Bad Rappenau"],"department":["Handchirurgie"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2026,8,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"594","DOI":"10.3238\/arztebl.m2024.0102","article-title":"The conservative and operative treatment of carpal fractures","volume":"121","author":"A Calvacanti Ku\u00dfmaul","year":"2024","journal-title":"Dtsch Arztebl Int"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"274","DOI":"10.1007\/s00068-025-02947-y","article-title":"Treatment modalities and patient reported outcomes in isolated and combined\n                    dorsal triquetrum chip fractures","volume":"51","author":"S Pasquinelli","year":"2025","journal-title":"Eur J Trauma Emerg Surg"},{"key":"ref3","first-page":"202","article-title":"Die dorsale Absprengung am Triquetrum und ihre Entstehung","volume":"25","author":"W Fischer","year":"1917","journal-title":"Fortschr R\u00f6ntgenstr"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"1612","DOI":"10.2106\/00004623-197254080-00003","article-title":"Traumatic instability of the wrist.
