Zusammenfassung

Isolierte Tuberculum-majus-Frakturen machen 14–21% der proximalen Humerusfrakturen aus. Tuberculum-minus-Frakturen finden sich hauptsächlich in Einzelfallbeschreibungen. Wir berichten von einem seltenen Fall einer Kombinationsfraktur von Tuberculum majus und Tuberculum minus ohne Einbeziehung des Collum anatomicum oder chirurgicum. Der Verletzungsmechanismus scheint auf einem komplexen Zusammenspiel zwischen Abduktion, Außenrotation mit Impaktion und Scherung gegen das Glenoid und Akromion zu beruhen.

Lesser tuberosity avulsion in combination with multifragment fracture of the greater tuberosity

A rare entity at the proximal humerus

Abtract

Isolated fractures of the greater tuberosity represent 14–21% of all proximal humeral fractures. Lesser tuberosity fractures have mainly been mentioned in case reports. We report a rare case of a combination of a lesser tuberosity avulsion with a multifragment fracture of the greater tuberosity of the proximal humerus in a young man. The injury mechanism might be a complex interaction between abduction and external rotation with impaction and shearing against the glenoid and acromion.
