Untere Gesäßlinie - Linea glutea inferior
The inferior gluteal line (inferior curved line), the least distinct of the three lines on the gluteal surface of ala of ilium, begins in front at the notch on the anterior border, and, curving backward and downward, ends near the middle of the greater sciatic notch. The surface of bone included between the anterior and inferior gluteal lines is concave from above downward, convex from before backward, and gives origin to the Glutæus minimus. Between the inferior gluteal line and the upper part of the acetabulum is a rough, shallow groove, from which the reflected tendon of the Rectus femoris arises.
