Zusammenfassung
Klinisches/methodisches Problem
Die postoperative radiologische Bildgebung des Sprunggelenks kann auch für den erfahrenen Radiologen eine besondere Herausforderung darstellen. Die komplex aufgebaute Anatomie des Sprunggelenks, mit seinen multiplen Gelenkflächen, Sehnen, Bändern und neurovaskulären Strukturen auf engstem Raum, kann durch Operationen signifikant verändert und insbesondere in der Magnetresonanztomographie (MRT) verfälscht dargestellt werden.
Radiologische Standardverfahren
Für eine fundierte Befundung und Beurteilung der Operationsergebnisse ist die Kenntnis der präoperativen Diagnose, Zeitpunkt und Technik der durchgeführten Operation(en) sowie der aktuellen klinischen Symptomatik von großer Bedeutung.
Empfehlung für die Praxis
Dieser Artikel konzentriert sich auf zu erwartende radiologische Veränderungen und gibt Tipps zur Befundung der postoperativen MRT des Sprunggelenks bei einer Auswahl relevanter operativer Eingriffe. Zudem wird auf mögliche postoperative Komplikationen und ihre radiologische Darstellung hingewiesen
Abstract
Clinical/methodical issue
Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI).
Standard radiological methods
Selecting the appropriate radiological modality is key to making the correct diagnosis. Therefore, knowledge of the initial and current symptoms is just as important as familiarity with the most frequently performed operations in the ankle.
Practical recommendations
This article aims to give its reader a summary of the most important and frequently performed operation techniques of the ankle and discusses the expected appearance and possible complications in postoperative imaging.
