Rupture of the distal biceps tendon

Abstract

Rupture of the distal biceps tendon is an injury most frequently occurring in middle-aged men (30–50 years). The typical mechanism is an eccentric load on the supinated forearm in a slightly flexed elbow position. There is an association with power sports and physically demanding activities. Epidemiological data show an increase in frequency in recent decades. Risk factors, such as the use of anabolic steroids, power sports and nicotine abuse, show an association with the injury. For less demanding patients or relevant comorbidities, a good functional result can be achieved with conservative treatment with subjectively good patient satisfaction; however, a relevant reduction in supination (40%) and flexion strength (20%) is to be expected. An operative refixation enables the best functional outcome to be achieved; however, surgical treatment is accompanied by a not inconsiderable risk for complications.
