Anterior gluteal line

The anterior gluteal line (middle curved line), the longest of the three gluteal lines, begins at the crest, about 4 cm. behind its anterior extremity, and, taking a curved direction downward and backward, ends at the upper part of the greater sciatic notch.

The space between the anterior and posterior gluteal lines and the crest is concave, and gives origin to the Glutæus medius.

Near the middle of this line a nutrient foramen is often seen.
