Zusammenfassung

Die Wahl der Materialkombination beim künstlichen Hüftgelenkersatz ist von klinischer Relevanz. Der vorliegende Übersichtsartikel betrachtet die technischen Unterschiede hinsichtlich des Verschleißes und der Korrosion der relevanten Materialkombinationen aus Keramik, Metall, keramisiertem Metall und verschiedenen Polyethylenarten. Die Materialeigenschaften, die häufig unter standardisierten Bedingungen im Labor erfasst wurden, werden mit den klinischen Ergebnissen anhand evidenzgraduierter klinischer Studien und auf Basis von Registerstudien verglichen. Diese Arbeit stellt somit als aktuelle Momentaufnahme Erwartungen und tatsächliche klinische Ergebnisse heutiger Materialkombinationen in einen gemeinsamen Kontext. Es zeigt sich, dass sich manche Tendenzen aus der Materialforschung, z. B. zum quervernetzten Polyethylen, mit den Beobachtungen aus der Klinik decken, während bei anderen Materialien technische Vorteile bislang nicht in einen relevanten klinischen Nutzen münden.

Notfall-TEP der Hüfte ist auch bei 90-Jährigen machbar

26.04.2024 Hüft-TEP Nachrichten

Ob bei einer Notfalloperation nach Schenkelhalsfraktur eine Hemiarthroplastik oder eine totale Endoprothese (TEP) eingebaut wird, sollte nicht allein vom Alter der Patientinnen und Patienten abhängen. Auch über 90-Jährige können von der TEP profitieren.

Arthroskopie kann Knieprothese nicht hinauszögern

25.04.2024 Gonarthrose Nachrichten

Ein arthroskopischer Eingriff bei Kniearthrose macht im Hinblick darauf, ob und wann ein Gelenkersatz fällig wird, offenbar keinen Unterschied.

Therapiestart mit Blutdrucksenkern erhöht Frakturrisiko

25.04.2024 Hypertonie Nachrichten

Beginnen ältere Männer im Pflegeheim eine Antihypertensiva-Therapie, dann ist die Frakturrate in den folgenden 30 Tagen mehr als verdoppelt. Besonders häufig stürzen Demenzkranke und Männer, die erstmals Blutdrucksenker nehmen. Dafür spricht eine Analyse unter US-Veteranen.

Ärztliche Empathie hilft gegen Rückenschmerzen

23.04.2024 Leitsymptom Rückenschmerzen Nachrichten

Personen mit chronischen Rückenschmerzen, die von einfühlsamen Ärzten und Ärztinnen betreut werden, berichten über weniger Beschwerden und eine bessere Lebensqualität.
