A novel surgical technique is described for the late repair of combined extensor carpi radialis longus and brevis tendon avulsion using suture anchor repair of the extensor CARS brevis and tenodesis of the retracted extensorCarpi radial is longus to the brevis. Extensor carpi radialis brevis is innervated directly by the radial nerve (C5- C8), or sometimes from its deep branch/posterior interosseous nerve. Muscles that move the fingers are often divided into extrinsic and intrinsic hand/finger muscles. Proximal: supracondylar ridge of humerus. Such stability is provided by the strong capsuloligamentous attachments and the unique bony architecture. 1 Extension at the wrist 2 .
