Introduction:

The anterior hip approach was described since 1881, since then several studies have been conducted that have shown significant advantages over the posterior and lateral direct approaches of the hip.

Material and method:

We conducted a descriptive study with continuous non-probabilistic cases at the Institute of Forensic Sciences from October 2015 to July 2017. Anatomy and distances were described to the neurovascular bundles. Correlation of Spearman’s Pearson and Rho was performed.

Results:

22 dissections were made, the Femorocutaneous Nerve was identified in 9 specimens, the average lateral Femorocutaneous Nerve distance at Smith-Petersen interval was 11.4 mm, We identified the Ascending Lateral Circumflex artery under the femoral rectum towards the central region of the approach, the separators could be placed around the coxofemoral joint without injuring vital structures, the riskier separator we place it in the anterior wall of the acetabulum, below the Psoasyland with an average distance 28.25 mm to the femoral package. The older you go, the longer the neurovascular bundles were located p < 0.05.

Conclusions:

High level of safety of the previous approach for hip replacement, distances to vital structures have a reasonable margin, hip replacement offers adequate joint exposure, direct acetabulum vision and atraumatic surgical dissection.
