greater sciatic notch การใช้

• It is fan-shaped, arising from the outer surface of the gluteal lines, and behind, from the margin of the greater sciatic notch.
• A vague line, the inferior gluteal line, might run from the AIIS to the greater sciatic notch which delineates the inferior extent of the gluteus minimus origin.
• The " inferior gluteal line " ( inferior curved line ), the least distinct of the three, 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 " anterior gluteal line " ( middle curved line ), the longest of the three, 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 " posterior gluteal line " ( superior curved line ), the shortest of the three, begins at the crest, about 5 cm . in front of its posterior extremity; it is at first distinctly marked, but as it passes downward to the upper part of the greater sciatic notch, where it ends, it becomes less distinct, and is often altogether lost.
