Zusammenfassung
Frakturen der proximalen Ulna sind häufige Verletzungen der oberen Extremität. Das
Ausmaß der Verletzungsschwere variiert von isolierten Frakturen des Olekranons bis
hin zu komplexen Luxationsfrakturen von Ellenbogengelenk und Unterarm. Im ersten Teil
des vorliegenden Artikels wird auf anatomische Besonderheiten der proximalen Ulna
eingegangen, die bei der osteosynthetischen Frakturversorgung von Bedeutung sind.
Im Hauptteil werden etablierte und moderne Verfahren zur operativen Stabilisierung
der Olekranonfraktur, der Monteggia-Verletzung und der Fraktur des Processus coronoideus
beschrieben und bezüglich der zu erwartenden Ergebnisse und Komplikationen diskutiert.
Abstract
Proximal ulna fractures are common injuries in the upper extremity. The severity of
injury ranges from isolated olecranon fractures to complex elbow fracture dislocations.
Relevant anatomic features of the proximal ulna for fracture management are presented
in the first part of this article. Furthermore, standard and recent techniques of
surgical treatment are described in detail for olecranon and Monteggia fractures as
well as for fractures of the coronoid process. Functional outcome and complications
of fracture treatment are discussed.
