Obwohl seit Anfang der 2000er Jahre Prothesen der vierten Generation in Deutschland verf\u00fcgbar sind, hat sich ihre Anwendung unter Handchirurginnen und -chirurgen bislang nur in begrenztem Umfang etabliert.<\/jats:p>\n                  <jats:p>Durch eine kombinierte Vorgehensweise wird zum einen eine Literatur\u00fcbersicht \u00fcber die Entwicklung der Endoprothetik des Handgelenkes, Komplikationen und Prothesenmodelle gegeben. Zum anderen wurde anhand einer online Umfrage die aktuelle Praxis der Handgelenksendoprothetik in Deutschland erhoben und durch die Ergebnisse einer prospektiven Datenerhebung von eigenen Patientinnen und Patienten mit Handgelenksprothesen erg\u00e4nzt. Hierf\u00fcr wurden die subjektive Handfunktion und Beschwerden anhand des DASH- und PRHWE-Scores, die Grobkraft und die Bewegungsausma\u00dfe nach Neutral-0-Methode ermittelt sowie Komplikationen und Sonderf\u00e4lle dargestellt.<\/jats:p>\n                  <jats:p>Von den befragten Handchirurginnen und -chirurgen gaben 38% an, Handgelenksprothesen zu implantieren. Gr\u00f6\u00dftenteils wurde die Implantation von Prothesen bei \u00e4lteren Patienten (&gt;40 Jahre) mit rheumatoider Arthritis, fortgeschrittenen posttraumatischen und idiopathischen Arthrosen sowie Osteonekrosen angewandt. Im Untersuchungszeitraum von Dezember 2022 bis August 2025 wurden 52 implantierte MOTEC\u00ae-Prothesen mit einem Nachuntersuchungszeitraum von mindestens einem Jahr erfasst. Es zeigte sich eine signifikante Verbesserung der Handfunktion, eine Reduktion von belastungsabh\u00e4ngigen Schmerzen und eine Verbesserung der Beweglichkeit (Extension\/Flexion, Radial-\/Ulnarduktion). Au\u00dferdem stellte sich ein Trend zur Verbesserung der Grobkraft dar, welcher jedoch bisher nicht das Signifikanzniveau erreichte. Es lie\u00dfen sich 14 Komplikationen beobachten, die gr\u00f6\u00dftenteils mechanisch sowie zum Teil infekti\u00f6s bedingt waren und durch eine chirurgische Revision behoben werden konnten.<\/jats:p>\n                  <jats:p>Zusammenfassend lassen sich auch bei Patientinnen und Patienten mit einem hohen funktionellen Anspruch, wie j\u00fcngere und handwerklich t\u00e4tige, zufriedenstellende funktionelle Ergebnisse nach Implantation von Handgelenksprothesen erzielen. Es besteht eine vergleichsweise hohe Lernkurve und eine erh\u00f6hte Komplikationsrate, insbesondere im Rahmen der ersten Prothesenimplantationen.<\/jats:p>","DOI":"10.1055\/a-2793-3639","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T23:30:24Z","timestamp":1773703824000},"page":"60-69","source":"Crossref","is-referenced-by-count":0,"title":["Endoprothetik
