Abstract

Background: Distal biceps tendon ruptures commonly present in the middle-aged population resulting in deficits of strength and endurance. Operative management has shown improved functional outcome; however, there is not a clear consensus on an ideal surgical method. Indications: Distal biceps tendon repair is indicated for patients with clinical evidence and supporting magnetic resonance imaging confirmation of complete or partial rupture of the biceps tendon. Ideally, surgery is performed within 1 to 2 weeks of the injury to minimize the amount of scar tissue that is formed and the severity of the tendon retraction. Technique Description: A single incision is created on the volar surface of the forearm approximately 15 mm distal to the main flexor crease. After dissection to and retrieval of the biceps tendon, a #2 FiberTag stitch is placed distally and secured in a standard looped, locking fashion. An anchor is then placed in the most proximal aspect of the radial tuberosity and preliminarily placed around the tendon. An all-suture intramedullary cortical button is then placed in the distal aspect of the radial tuberosity. The FiberTag sutures are then shuttled through the button and tightened to anatomically reduce the distal biceps. The sutures on the proximal anchor are then used as supplemental fixation. Results: An anterior, single incision technique provides exposure necessary for dual anchor fixation and anatomic restoration of the distal biceps tendon. Utilizing this approach, patients are found to have improved flexion and pronation at 1 year, lower rates of heterotopic ossification, and lower rates of reoperation. Conclusion: Distal biceps tendon repair through an anterior, single incision provides excellent exposure for surgical repair. Utilizing a dual anchor technique, the distal button allows for anatomic fixation while the proximal suture anchor provides secondary fixation and increases the bone-tendon interface.
