The bicipital tuberosity was exposed and the biceps tendon detached. The supinator and PIN were exposed dorsally. A K\u2010wire was drilled perpendicular to the surface of the tuberosity. By use of digital calipers, the distance from the exit point of this wire to the PIN was measured. The length of the bone tunnel was also measured. This wire was removed, and a second was drilled from the same starting point but directed 30\u00b0 ulnarly. Measurements were repeated. A Wilcoxon signed rank test was used to compare the distances of the K\u2010wire to the PIN and the tunnel lengths for both trajectories.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      With the perpendicular wire, the mean distance to the PIN was 11.1 mm. When directed 30\u00b0 ulnarly, the mean distance was 16.4 mm. The difference was significant (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001).
