Wahl der richtigen Gleitpaarung in der Hüftendoprothetik

Zusammenfassung

Der Operateur hat in der Hüftendoprothetik die Auswahl zwischen verschiedenen Materialgleitpaarungen, welche sich in Hart-Weich-Gleitpaarungen, Hart-Hart-Gleitpaarungen und alternative Materialien unterteilen lassen. Idealerweise sollte die Auswahl anhand von evidenzbasierten Daten zu den Verschleißeigenschaften, der Revisionswahrscheinlichkeit und potenziellen, patientenindividuellen Risiken der jeweiligen Materialkombination erfolgen. Während für einige Gleitpaarungen eine recht hochwertige Datenlage vorliegt, existieren zu manchen Materialien kaum zuverlässige Daten. Daher soll die vorliegende Arbeit dem Operateur Bewertungskriterien für die Selektion der Gleitpaarung vermitteln und eine Übersicht über die aktuelle Datenlage der verschiedenen Materialkombinationen geben.

Abstract

Different bearing materials are available in total hip arthroplasty and itʼs the surgeon who has the choice between hard-on-soft, hard-on-hard and alternative materials. Ideally, the material selection should rely on evidence-based data regarding the wear performance, the incidence of revision surgery and other potential bearing-associated risk factors for the corresponding combinations of materials in the individual patient. While there are high-quality studies available for some materials, adequate data is lacking for other materials. Therefore, the current article aims to provide bearing selection criteria for the surgeon and to review the current literature regarding different combinations of bearing materials in total hip arthroplasty.
