Before dissection, a 3\u2010dimensional coordinate\u2010measuring device was used to record the neutral orientation of the femur in the acetabulum. The specimens were then dissected free of all extra\u2010articular soft tissue, except for the ligamentum teres and the obturator neurovascular bundle, and digitized. An anatomic femoral reconstruction tunnel through the femoral neck was simulated and extended along its axis into the acetabulum. The femur was digitally rotated internally from 0\u00b0 to 30\u00b0 and externally from 0\u00b0 to 40\u00b0, as well as abducted from 0\u00b0 to 30\u00b0 and adducted from 0\u00b0 to 20\u00b0, in increments of 1\u00b0. At each position, the location of the simulated acetabular reconstruction tunnel was measured with respect to the obturator bundle and the edge of the acetabular fossa.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The anatomic reconstruction tunnel entered the lateral side of the femur at a mean distance of 7.0\u00a0mm distal and 5.8\u00a0mm anterior to the center of the vastus ridge. By angling the femur at 15\u00b0 of internal rotation and 15\u00b0 of abduction, the obturator neurovascular bundle was avoided in 100% of specimens.<\/jats:p>\n                  <\/jats:sec>\n
