Endoscopic Distal Biceps Repair: Endoscopic Anatomy and Dual-Anchor Repair Using a Proximal Anterolateral "Parabiceps Portal".


ABSTRACT: Distal biceps rupture is associated with significant functional disability, and surgical treatment involves open or endoscopic-assisted repair of the ruptured tendon through an anterior incision. This report describes an endoscopic approach that is performed with 2 portals for visualization and instrumentation. Preoperative sonography is used to identify bony and soft-tissue landmarks. The viewing portal is a proximal anterolateral "parabiceps portal" developed by the author, and the landmarks and relevant anatomic relations have been derived from a preliminary anatomic study. The working portal is a distal anterior portal and permits access to the radial tuberosity through the internervous muscular plane. The parabiceps portal permits visualization of the anterior and medial region of the radial tuberosity. A detailed description of the endoscopic pathoanatomy of the distal biceps tendon region is presented. The distal anterior portal is used for retrieval of the ruptured tendon, and thereafter the tuberosity is debrided and anchors are placed under vision. The ruptured tendon is whipstitched and docked onto the tuberosity, and nonsliding knots are used to securely reattach the tendon to bone. Overall, the 2-portal technique provides a method for tendon repair under direct visualization and is safe and reproducible.
