Zusammenfassung

Frakturen in unmittelbarer Nachbarschaft zum akromioklavikularen (AC-)Gelenk sind selten und stellen eine eigene Entität dar. Insbesondere Frakturen der lateralen Klavikula weisen eine überdurchschnittlich hohe Rate an Pseudarthrosen unter konservativer Therapie auf. Therapeutisches Ziel ist in jedem Fall eine gute Schulterfunktion, die durch Frakturkonsolidierung unter Vermeidung von signifikanten Fehlstellungen erreicht werden kann. Instabile Frakturen müssen dazu als solche erkannt werden und mit einem geeigneten Verfahren osteosynthetisch versorgt werden. Neben den Platten- und Kirschner-Drahtosteosynthesen werden zunehmend auch arthroskopische Verfahren mit einer Reaproximierung der Frakturenden eingesetzt. Frakturen des Akromions werden überwiegend mit der Plattenosteosynthese versorgt.

Abstract

Fractures of the lateral clavicle and the acromion are uncommon and represent a separate entity. Fractures of the lateral clavicle demonstrate a high rate of problems, such as non-union, malunion and functional impairment when treated nonoperatively. The aim of any treatment option is full restoration of shoulder function by achieving fracture healing without significant malpositioning. Unstable fracture patterns have to be identified and should be fixed using an appropriate technique, which include plating, K-wire fixation and arthroscopic techniques which bring the dislocated fragments into contact. Dislocated fractures of the acromion can usually be treated by plating.
