Iliac tubercle

Iliac tubercle is a prominent anatomical structure located on the ilium, the largest bone of the pelvis. It is a part of the Iliac crest, which is the superior border of the ilium. The iliac tubercle is an important landmark in clinical medicine and surgery, as it is used for orientation in various surgical procedures and for the measurement of the Pelvic Inlet.

Etymology

The term "iliac" is derived from the Latin "ilium", which refers to the flank or loin. The term "tubercle" is derived from the Latin "tuberculum", which means a small swelling or lump.

Anatomy

The iliac tubercle is located approximately 5 cm posterior to the anterior superior iliac spine (ASIS). It is the most lateral point of the iliac crest. The iliac tubercle is palpable in most individuals and serves as an important landmark in clinical examination and surgical procedures.

Clinical significance

The iliac tubercle is used as a landmark for various surgical procedures. For example, it is used for orientation in the Kocher-Langenbeck approach to the acetabulum. It is also used as a reference point for the measurement of the pelvic inlet in obstetrics.
