Iliac tuberosity

Iliac Tuberosity is a specific part of the ilium, one of the three bones that make up the hip bone. It is located on the internal surface of the ilium, and serves as the attachment point for certain ligaments and muscles.

Etymology

The term "iliac" comes from the Latin "ilium," which refers to the upper and biggest part of the hip bone. "Tuberosity" is derived from the Latin "tuberositas," meaning a lump or swelling, often used in anatomical contexts to denote a rounded projection or protuberance.

Anatomy

The iliac tuberosity is a roughened area on the internal surface of the ilium, located above the iliac fossa and behind the iliac crest. It is the point of attachment for the iliolumbar ligament and the iliocostalis muscle.

Clinical Significance

Due to its role as an attachment point for ligaments and muscles, the iliac tuberosity can be involved in certain medical conditions. For example, inflammation or injury to the iliolumbar ligament can cause pain in the lower back and hip area. This condition is known as Iliolumbar syndrome.
