Zusammenfassung
Das Ellenbogengelenk ist eines der am häufigsten verletzten Gelenke bei Sportlern. Besonders betroffen sind Gewichtheber, Golfspieler, Tennisspieler und klassischerweise auch Baseballspieler (Pitcher). Verletzungen bei Wurfsportarten basieren in der Regel auf dem pathophysiologischen Modell des „valgus extension overload syndrome“. Die Verletzungen sind meist komplex und erfordern für eine präzise radiologische Diagnose eine Kenntnis sowohl der Klinik als auch der genauen Anatomie und Biomechanik. Die typischen Verletzungsmuster der jeweiligen Sportarten sind auf den erhöhten Varus- oder Valgusstress in Flexion oder Extension zurückzuführen. Häufig basiert eine akute Schmerzsymptomatik auf einer chronischen Vorschädigung der Sehnen und des Bandapparats durch Überlastung.
Abstract
The elbow is one of the most commonly injured joints in sports activities. In particular, weight lifters, golfers, tennis players, and pitchers are affected. Injuries in sports involving overhead throwing are commonly based on the pathophysiologic model of valgus extension overload syndrome. The injuries are commonly complex and demand a good knowledge of the symptoms, the exact anatomy, and the biomechanics to arrive at a precise radiologic diagnosis. The characteristic patterns of injury that occur in specific sports activities are related to a combination of increased varus or valgus and extension or flexion overload that results in tensile forces and/or compression and shear stress. Acute symptoms are frequently based on chronic degeneration of the tendons and ligamentous structures due to repetitive microtrauma from overuse syndrome.
