Auch im Rahmen von Revisionseingriffen nach fehlgeschlagenen Operationen am Trapezium oder an der Basis des ersten Mittelhandknochens, kann eine Prothese eingesetzt werden. Revisionen sind technisch anspruchsvoll, da ver\u00e4nderte anatomische Strukturen, Narbengewebe und limitierte Knochenqualit\u00e4t die Implantation erschweren k\u00f6nnen.<\/jats:p>\n                  <jats:p>Anhand konkreter F\u00e4lle werden verschiedene Indikationen und Techniken vorgestellt: die Implantation einer Endoprothese nach fehlverheilten Bennett- oder Rolando-Frakturen, bei persistierender Luxation des DSG, nach Proximalisierung des ersten Strahls infolge Trapezektomie mit Implantation der Pfanne in das Os scaphoideum sowie bei kn\u00f6chernem Defekt des Trapeziums im Rahmen vorausgegangener Prothesenimplantation.<\/jats:p>\n                  <jats:p>Bei f\u00fcnf Patienten mit posttraumatischer Arthrose f\u00fchrte die Endoprothesenimplantation zu guter Schmerzreduktion und Funktionswiederherstellung. Zw\u00f6lf Patienten mit Pfannenimplantation in das Scaphoid nach Trapezektomie zeigten durchgehend eine suffiziente Schmerzreduktion und Regeneration der Handfunktion; die Patientenzufriedenheit war hoch. In einem weiteren Fall gelang die Rekonstruktion des Trapeziums mittels trikortikalem Beckenkammspan mit anschlie\u00dfender Reimplantation der Pfanne. Kurzfristig traten keine gravierenden Komplikationen auf.<\/jats:p>\n                  <jats:p>Die DSG-Endoprothetik stellt neben der Prim\u00e4rversorgung auch im Revisionssetting eine effektive Behandlungsoption dar \u2013 sowohl bei posttraumatischen Beschwerden als auch bei Proximalisierung des ersten Strahls nach Trapezektomie. Entscheidend ist dabei die Anpassung an die besonderen anatomischen und biomechanischen Bedingungen des voroperierten Gelenks. Erfahrung mit Prim\u00e4rimplantationen gilt als Voraussetzung, um das Komplikationsrisiko zu minimieren. Langzeitstudien sind erforderlich, um die Endoprothetik im direkten Vergleich mit etablierten Rettungsoperationen wie Trapezektomie oder Arthrodese, im Sinne eines Salvage-Verfahrens, zu bewerten.<\/jats:p>","DOI":"10.1055\/a-2786-5903","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T23:30:24Z","timestamp":1773703824000},"page":"17-27","source":"Crossref","is-referenced-by-count":0,"title":["Endoprothetik nach Voroperationen am Daumensattelgelenk \u2013 Pearls and Pitfalls, Off-Label-Use und Alternativen"],"prefix":"10.1055","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0374-1528","authenticated-orcid":false,"given":"Victoria","family":"Struckmann","sequence":"additional","affiliation":[{"name":"Klinik f\u00fcr Handchirurgie, Plastische und Rekonstruktive Chirurgie, Verbrennungszentrum, an der Universit\u00e4t Heidelberg, Ludwigshafen, Deutschland, BG Klinik Ludwigshafen, Ludwigshafen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Krohn","sequence":"additional","affiliation":[{"name":"Sektion Orthop\u00e4die, Unfallchirurgie, Hand- und Wiederherstellungschirurgie, St Franziskus-Hospital Ahlen GmbH, Ahlen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin","family":"Panzram","sequence":"additional","affiliation":[{"name":"Zentrum f\u00fcr Orthop\u00e4die, Unfallchirurgie und Paraplegiologie, Universit\u00e4tsklinikum Heidelberg, Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2026,3,16]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"961","DOI":"10.1177\/17531934211024500","article-title":"Dual mobility trapeziometacarpal prosthesis: a prospective study of 107 cases with a follow-up of more than 3 years","volume":"46","author":"B Lussiez","year":"2021","journal-title":"J Hand Surg Eur Vol"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"877","DOI":"10.1177\/17531934231179581","article-title":"Low complication rate and high implant survival at 2 years after Touch(R) trapeziometacarpal joint arthroplasty","volume":"48","author":"D B Herren","year":"2023","journal-title":"J Hand Surg Eur Vol"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"760","DOI":"10.1016\/j.hansur.2021.08.005","article-title":"Touch(R) double mobility arthroplasty for trapeziometacarpal osteoarthritis: outcomes for 92 prostheses","volume":"40","author":"P Gonzalez-Espino","year":"2021","journal-title":"Hand Surg Rehabil"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"102167","DOI":"10.1016\/j.hansur.2025.102167","article-title":"Five-to-8-year prospective follow-up of 61 Touch(R) trapeziometacarpal prostheses","volume":"44","author":"C Falaise","year":"2025","journal-title":"Hand Surg Rehabil"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"219","DOI":"10.1016\/j.jhsa.2005.10.018","article-title":"Revision of thumb trapeziometacarpal arthroplasty","volume":"31","author":"W P Cooney","year":"2006","journal-title":"J Hand Surg Am"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"205","DOI":"10.1007\/s00402-010-1128-x","article-title":"Revision surgery after trapeziometacarpal arthroplasty","volume":"131","author":"K Megerle","year":"2011","journal-title":"Arch Orthop Trauma Surg"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"128","DOI":"10.1007\/s00402-025-05751-w","article-title":"Scapho-metacarpal dual mobility prosthesis for TMC-1 joint salvage: technical insights","volume":"145","author":"J Glaser","year":"2025","journal-title":"Arch Orthop Trauma Surg"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"533","DOI":"10.1016\/0266-7681(93)90166-d","article-title":"Revision procedures for complications of surgery for osteoarthritis of the carpometacarpal joint of the thumb","volume":"18","author":"W B Conolly","year":"1993","journal-title":"J Hand Surg Br"},{"key":"ref9","doi-asserted-by":"publisher","first-page":"300","DOI":"10.1055\/s-0042-113774","article-title":"Die Rettungsoperation mittels Mini TightRope(R) bei schmerzhafter Proximalisierung des 1.
