Surgical Anatomy of the Distal Biceps Tendon
The distal biceps tendon (DBT) anatomy is complex, and its structural and insertional morphology has surgical implications. The DBT has long and short tendon components, and these show three variable insertional footprints into the radial tuberosity. The DBT insertion passes through the proximal radioulnar space (RUS) during dynamic rotation, and an alteration in RUS or DBT dimensions may predispose to impingement and wear. The DBT is closely related to neurovascular structures of the cubital fossa, and these structures are potentially at risk during open and endoscopic surgery. Detailed knowledge of the structural, insertional, and neurovascular anatomy of the DBT is necessary to safely replicate DBT kinematics during repair and reconstructive surgery for distal biceps pathology.
