(A) Viewing this left elbow from the medial side, one can see that the graft has been passed through the ulna and the sutured end is docked in the 4.5-mm socket. The free end is then tensioned across the entry site of the socket, and the length is marked at this location. A Krackow suture is placed at this location, and the excess graft is trimmed. This suture is passed into the 4.5-mm socket and retrieved through the empty 1.5-mm socket. (B) After both ends are docked, the graft is tensioned and the sutures are securely tied over the bone bridge between the two 1.5-mm sockets. (UCL, ulnar collateral ligament.)
