Figure 6. The ulnar tunnels were prepared as follows: the more distal at the level of the supinator crest and the more proximal at the level of the insertion of the annular ligament, leaving a 1.5-cm bone bridge between them, so that they are convergent. Humeral tunnels: one measuring 4.5 cm made at the isometric point, and another two proximal and convergent to the first tunnel, measuring 3.5 cm in "Y" configuration.
