Single-Incision Reconstruction of Chronic Distal Biceps Ruptures Using FCR/PL Autograft and Endobutton Fixation

Ruptures of the distal head of the biceps are quite common and are a consequence of eccentric load. Chronic lesions are defined as treated after 4 weeks from injury. Treatment of chronic lesions is challenging and typically requires a tendon graft due to proximal stump retraction and degeneration. We propose a new reconstruction technique using a Flexor Carpi Radialis (FCR) autograft reinforced with a Palmaris Longus (PL) autograft and fixed to the radial tuberosity with an Endobutton. We applied this technique in 6 patients with excellent functional outcomes. No major complications were observed and no morbidity or functional limitations were noticed at the harvest sites.
