The Pelvic (Hip) Girdle Flashcards

Ilium
The ilium connects posteriorly with the sacrum at the sacroiliac joint.

Pubis
The pubis is the most anterior part of a coxal bone.

Ischium
The ischium is the “sit-down bone,” so called because it forms the most inferior part of the coxal bone.

Iliac Crest
The upper edge of an ala, the iliac crest, is an important anatomical landmark that is always kept in mind by those who give intramuscular injections.
It ends anteriorly in the anterior superior iliac spine and posteriorly in the posterior superior iliac spine.

Sacroiliac Joint
The sacroiliac joint is a large, flaring bone that forms most of the hip bone.

Ischial Spine
The ischial spine, superior to the tuberosity, is another important anatomical landmark, particularly in the pregnant woman, because it narrows the outlet of the pelvis through which the baby must pass during birth.

Acetabulum
The ilium, ischium, and pubis fuse at the deep socket called the acetabulum, which means “vinegar cup.”
The acetabulum receives the head of the thigh bone.

Pubic Symphysis
The pubic bones of each hip bone fuse anteriorly to form a cartilaginous joint, the pubic symphasis.

Greater Sciatic Notch
This allows blood vessels and the large sciatic nerve to pass from the pelvis posteriorly into the thigh.
Injections in the buttock should always be given well away from this area.
