The lateral cutaneous branch ("iliac branch") pierces the internal oblique muscles and the external oblique muscles immediately above the iliac crest. [4] It is distributed to the skin of the gluteal region, behind the lateral cutaneous branch of the subcostal nerve; the size of this branch bears an inverse proportion to that of the lateral cutaneous branch of the subcostal nerve.
Posterior gluteal line, also known as the superior curved line, the shortest of the three gluteal lines, begins at the iliac 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.
The gluteus medius muscle starts, or "originates", on the outer surface of the ilium between the iliac crest and the posterior gluteal line above, and the anterior gluteal line below; the gluteus medius also originates from its own fascia, the gluteal aponeurosis, that covers its outer surface.
The gluteus maximus arises from the posterior gluteal line of the inner upper ilium, and the rough portion of bone including the crest, immediately above and behind it; from the posterior surface of the lower part of the sacrum and the side of the coccyx; from the aponeurosis of the erector spinae (lumbodorsal fascia), the sacrotuberous ligament, and the fascia covering the gluteus medius.
The severity of symptoms of damage to the iliohypogastric nerve can show whether damage occurred above or below the anterior superior iliac spine. [6] Bone may be harvested from the nearby iliac crest for use elsewhere in the body. [5] As the subcostal nerve lies close to the anterior superior iliac spine, this is put at risk of damage. [5]
The lower part of the muscle also acts as an adductor and external rotator of the limb. The upper fibers act as abductors of the hip joints. The upper fibers act as abductors of the hip joints. The gluteus maximus is a tensor of the fascia lata , and by its connection with the iliotibial band steadies the femur on the articular surfaces of the ...
The iliohypogastric nerve runs posterior to the psoas major on its proximal lateral border to run laterally and obliquely on the anterior side of quadratus lumborum. Lateral to this muscle, it pierces the transversus abdominis to run above the iliac crest between that muscle and abdominal internal oblique. It gives off several motor branches to ...
They travel inferiorly through multiple layers of muscles, then traverse osteofibrous tunnels between the thoracolumbar fascia and iliac crest. [1] Dysfunction of the superior cluneal nerves is often due to entrapment as the nerves cross the iliac crest – this can result in numbness, tingling or pain in the low back and upper buttocks region.
