The largely immobile sacroiliac joint is supported by a pair of strong ligaments that are attached between the sacrum and ilium portions of the hip bone. These are the anterior sacroiliac ligament on the anterior side of the joint and the posterior sacroiliac ligament on the posterior side.
What attaches to the anterior inferior iliac spine?The anterior inferior iliac spine (AIIS) is bony prominence on the anterior border of the ilium forming the superior border of the acetabulum. Attachments include the Iliacus, origin of straight head of the rectus femoris, and also the proximal ileofemoral ligament (Y-ligament or ligament of Bigelow).

The iliac crest has a large amount of red bone marrow, and thus it is the site of bone marrow harvests (from both sides) to collect the stem cells used in bone marrow transplantation. The iliac crest is also considered the most ideal donor site for bone grafting when a large quantity of bone is needed.
Why does my iliac crest hurt after running?

Osteitis pubis is a condition in which the pubic bone or the surrounding tissues are inflamed and sore. This pain is most often related to complications from surgery but has also been found to occur in athletes. Early diagnosis of osteitis pubis is important to avoid further pubic bone stress.

Iliac Tubercle or Tubercle of the iliac Crest (Tuberculum iliac) is a prominent bulge on the outer lip of the iliac crest, near its midpoint. This area is an attachment site for the iliotibial tract or band.
What are the attachments of the Sacrotuberous ligament?
The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which it is partly blended), to the lower transverse sacral tubercles and the lateral margins of the lower sacrum and upper coccyx.
What is Sacrococcygeal ligament?
The posterior sacrococcygeal ligament or dorsal sacrococcygeal ligament is a ligament which stretches from the sacrum to the coccyx and thus dorsally across the sacrococcygeal symphysis shared by these two bones.
Where does the Iliolumbar ligament attach?
The iliolumbar ligaments are crucial in supporting the lower lumbar spine; they join the 4th and 5th lumbar vertebrae (L4 and L5) to the iliac bone crest at the back of the pelvis.
Where is the ischial Ramus?
The ramus of the ischium extends downwards from the body of ischium and then turns anteriorly and to unite with the inferior ramus of the pubic bone. Several surfaces and borders of the ischium are described: An anterior surface. A posterior surface divided into perineal and pelvic areas.
What is the posterior iliac spine?
The posterior inferior iliac spine (Sweeney’s Tubercle) is an anatomical landmark that describes a bony “spine”, or projection, at the posterior and inferior surface of the iliac bone. It is one of two such spines on the posterior surface, the other being the posterior superior iliac spine.
What muscle originates at the posterior inferior iliac spine?
Gluteus Maximus is the largest muscle of the gluteal group. It originates on the iliac crest, the lateral surface of the ilium, sacrum, and coccyx. The insertion point is along the iliotibial tract and the gluteal tuberosity.
