Single-Incision Technique for Repair of Distal Biceps Tendon Avulsions With Intramedullary Cortical Button

Abstract

Patients who experience distal biceps tendon avulsions generally benefit from surgical intervention. Compared with nonoperative treatment, surgery has shown improved muscle endurance as well as increased flexion and supination strength. Although a number of surgical techniques exist, repair of the distal biceps through a single incision is gaining popularity. This may be due in part to patient preference and emerging technologies such as cortical button fixation, suture anchors, and intraosseous screws. In this report, we present a simple technique for anatomically repairing distal biceps injuries using an intramedullary tenodesis button. This technique has the benefit of using a single unicortical drill hole in the radius while allowing the surgeon to sequentially tighten the tendon to its desired level of tension. When appropriate surgical steps are followed, it can be completed in a reliable, safe, and efficient manner through a single incision.
