The iliolumbar ligament is a strong band of connective tissue which courses from the transverse process of L5 (in over 96% of cases) to the posterior iliac wing and crest of the ilium. It functions to maintain the alignment of L5 on the sacrum during various movements 1,2.
It is an important landmark in correct labeling of vertebral levels in patients with lumbosacral transitional vertebrae (LSTV) 4.
