Dislozierte Meniskusläsionen
Displaced Meniscal TearsZusammenfassung
Die MRT ist als nicht invasive Methode mit hohem Weichteilkontrast zum Goldstandard in der Diagnostik von Meniskusläsionen geworden. Verlagerte Meniskusanteile sind oft eine Blickdiagnose. Manchmal sind jedoch nur kleine Anteile betroffen, die der Wahrnehmung entgehen können. Dieser Beitrag erklärt die Grundlagen von Meniskusrissen, wie Meniskusdislokationen entstehen und die Zeichen, an denen Verlagerungen zu erkennen sind.
Abstract
As a non-invasive method with high soft-tissue contrast, MRI is gold standard in the diagnosis of meniscal lesions. Dislocated meniscus tears are most of the time simple to diagnose. Sometimes, however, only small portions are affected which can be overlooked. The exact description of the tear is important for the further therapeutic approach and thus basis of the radiological report. This article explains the basics of meniscus tears, how meniscus dislocations occur and shows signs how those shifts can be recognized.
-
Eine der wichtigsten Aufgaben der Menisken ist eine adäquate Druckverteilung. Bei einem Riss kann diese Aufgabe, abhängig vom Rissverlauf, nicht mehr erfüllt werden und es kommt zu einer vorzeitigen Arthrose.
-
Der Verlauf eines Risses gibt Aufschluss über potenzielle Verlagerungsmöglichkeiten. Je länger der Riss ist, umso wahrscheinlicher ist eine Verlagerung.
-
Verlagerten Meniskusanteilen kommt eine besondere Bedeutung zu, weil diese oft eine operative Behandlung erfordern.
-
Die Kenntnis der Anatomie, der Varianten und der radiologischen Zeichen ebnet den Weg zur richtigen Diagnose und hilft den behandelnden Ärztinnen und Ärzten dabei, eine adäquate Therapie einzuleiten und unnötige Operationen zu vermeiden.
