Definition
The term iliac crest refers to the free cranial edge of the wing of the ilium.
Anatomy
The iliac crest extends from the anterior superior iliac spine (anterior end) to the posterior superior iliac spine (posterior end). It has two bony lips and an intermediate line, which serve as the insertion or origin of various muscles:
- Labium externum (insertion of the obliquus externus abdominis muscle)
- Linea intermedia (origin of the obliquus internus abdominis muscle)
- Labium internum (origin of the transversus abdominis muscle)
Clinic
The iliac crest is an important anatomical reference point. It is thickened and easily palpable from the outside through the skin. Due to its easy access, it serves as a bone marrow harvesting site.
The horizontal connection between the two highest points of the iliac crest is known as the Jacoby line. The transverse plane in which these two points lie is called the supracristal planum.
