Introduction The most inferior branch (MIB) of the superior gluteal nerve (SGN) is vulnerable during direct lateral approach to the hip. A safe distance proximal to the tip of the greater trochanter varying from 3 to 5 cm has been reported in different studies. Anatomical studies defining safe zones and clinical studies reporting the results use various reference points, and the oblique course of the MIB contributes to the confusion. Numerous efforts have been made to standardize the safe zone using patient characteristics such as body height; however, contradictory results have been reported. The purpose of this study was to measure the safe distance in line to the gluteal split and also to determine the relationship of the safe distance with femoral length, as a stable component of body height.
