Proximale Ulnafrakturen

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.
