Verletzungen des Akromioklavikulargelenks: Neues zur Biomechanik, Klassifikation, Diagnostik und Indikationsstellung

In recent years, new options for the treatment of the acromioclavicular joint have become available and are reflected in the classification, diagnosis and indication of acute injuries. Horizontal instability in particular has become the focus of scientific attention and has been taken into account both in the imaging diagnostic workup and in the development of new classification systems and surgical stabilization techniques. To what extent this will be of clinical relevance in daily care must be shown by future high-quality studies. Standard imaging includes weighted panoramic images and a bilateral Alexander view. With regard to surgical indication, higher degrees of injury (types 4 to 6) are still considered a clear indication, while types 1 to 3 should be treated conservatively. Biomechanical data indicate that the treatment should be as anatomical as possible, addressing both vertical and horizontal instability.
