Abstract
Since the 1970s, numerous designs of reverse shoulder arthroplasty (RSA) have been proposed, and in 1994, Grammont came up with the third variation of his Delta Reverse, which facilitated pain relief and recovery of overhead motion in the cuff-deficient arthritic shoulder. These satisfactory results have led to an expansion in the indications including to younger more active patients and also to patients with an intact rotator cuff. However, over time, surgeons have identified adverse effects related to the design of the implant. Thus, the field has seen a push for advances in the design of the different components of the RSA as well as in the positioning of these implants. The objective of this review paper is to a) provide a comprehensive overview of the developments in the design of the components of RSA and to b) identify the best combination of components for RSA in 2022.
Zusammenfassung
Seit den 1970er-Jahren hat wurden zahlreiche Vorschläge für die Gestaltung der inversen Schulterendoprothese (RSA) gemacht, und 1994 stellte Grammont die dritte Variante seines Delta-Reverse-Modells vor, mit welcher die Schmerzlinderung und die Wiederherstellung der Überkopfbewegung in der arthritischen Schulter mit Rotatorenmanschettendefekt erleichtert wurden. Diese zufriedenstellenden Ergebnisse führten zur Ausweitung der Indikationen auch auf jüngere, aktivere Patienten und auf Patienten mit intakter Rotatorenmanschette. Jedoch wurden mit der Zeit unerwünschte Auswirkungen durch Chirurgen festgestellt, die mit dem Design des Implantats zusammenhängen. Deshalb gab es einen Schub für Fortschritte in diesem Bereich in Bezug auf die Gestaltung der unterschiedlichen Bestandteile der RSA sowie im Hinblick auf die Positionierung solcher Implantate. Ziel der vorliegenden Übersichtsarbeit ist es, a) einen umfassenden Überblick über die Entwicklungen beim Design der Komponenten für die RSA zu geben und b) die beste Kombination aus den Komponenten für eine RSA im Jahr 2022 zu ermitteln.
