Acute, traumatic distal biceps tendon injuries are common among the middle-aged athletic male population. Surgical repair of distal biceps tendon remains the most effective means to restore maximal strength of forearm supination and elbow flexion with relief of antecubital pain. To date, no consensus exists on the optimal fixation method during distal biceps tendon repair and multiple techniques are accepted, including 1- and 2-incision approaches and tendon fixation with suture anchors, transosseous sutures, interference screws, and cortical buttons. In this Technical Note, we demonstrate a distal biceps tendon repair technique using a single-incision approach with bicortical, tensionable suspensory button fixation.
