PATIENTS AND METHODS Fifteen cadaveric hip specimens were dissected to establish the course of branches of the lateral femoral cutaneous nerve. The number of branches divided by each of the three incisions was recorded. RESULTS The MIS incisions resulted in significantly less nerve division compared with the SLA. The mean difference between the SLA and the ALA was 4.4 (P < 0.0001), and between the SLA and the PA was 1.4 (P = 0.0005). The ALA divided significantly fewer nerves compared with the PA (mean difference = 3; P = 0.0001). DISCUSSION There is little evidence of the benefit of one MIS approach over another in the literature. The ALA preserved significantly more cutaneous nerves in this study. These results need corroboration with clinical outcomes to determine their significance.
