Distal biceps rupture in a snowboarder.
As in this case study of a snowboarder, the typical history for distal biceps brachii rupture involves a single traumatic event, an audible popping sound, and intense pain. The physical exam will reveal ecchymosis in the antecubital area and weakness with both supination and elbow flexion; the distal biceps brachii tendon will not be palpable. Though distal biceps rupture is far less common than its proximal counterpart, primary care physicians should be aware of the diagnostic criteria. Referral for surgical treatment is necessary to preserve elbow flexion and supination strength.
