Fig 3.

Looking at the anterior aspect of this left arm, the radial tuberosity is again exposed after the button has been threaded onto the sutures of the tendon. (A) A 3.2-mm hole is drilled in the center of the footprint through the near cortex only. With the elbow in approximately 30° of flexion, the button is advanced into the intramedullary canal of the radius. It is then flipped and the sutures are sequentially tightened. This secures the tendon to its native footprint on the radial tuberosity. The sutures are then securely tied and cut. (B) This figure shows the final appearance of the tendon after repair.
