The anterior inferior iliac spine (AIIS) is a bony eminence on the anterior border of the hip bone, or, more precisely, the wing of the ilium. Structure.
The ilium (/ ˈ ɪ l i ə m /) (pl.: ilia) is the uppermost and largest region of the coxal bone, and appears in most vertebrates including mammals and birds, but not bony fish.All reptiles have an ilium except snakes, although some snake species have a tiny bone which is considered to be an ilium.
The ilium is a bone of the pelvic girdle with four bony projections, each serving as attachment points for muscles and ligaments: Anterior superior iliac spine; Anterior inferior iliac spine; Posterior superior iliac spine; Posterior inferior iliac spine
The greater sciatic notch is a notch in the ilium, one of the bones that make up the human pelvis. It lies between the posterior inferior iliac spine (above), and the ischial spine (below). The sacrospinous ligament changes this notch into an opening, the greater sciatic foramen .
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 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 gluteus 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.
The anterior gluteal line is the middle curved gluteal line on the hip bone. It is the longest of the three gluteal lines, begins at the iliac 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 iliac fossa is bounded above by the iliac crest, and below by the arcuate line. It is bordered in front and behind by the anterior and posterior borders of the ilium. The iliac fossa gives origin to the iliacus muscle. [1] The obturator nerve passes around the iliac fossa. [2] It is perforated at its inner part by a nutrient canal.
