The iliolumbar ligament is a strong band of connective tissue and one of the three vertebropelvic ligaments. ... The iliolumbar ligaments are crucial in supporting the lower lumbar spine; they join the 4th and 5th lumbar vertebrae (L4 and L5) to the iliac bone crest at the back of the pelvis.

What is the function of the Iliolumbar ligaments?

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.

3. Chronic cases frequently need injections of local anaesthetic (and sometimes steroid) along the posterior iliac crest.

Can you palpate the iliolumbar ligament?

The iliac insertion of the iliolumbar ligament is inaccessible to palpation, being shielded by the iliac crest. The dorsal rami of L1 or L2 nerve roots, however, cross the crest at 7 cm from the midline, and this distance closely correlates with the dorsal projection of the iliolumbar ligament insertion.

Where does iliolumbar ligament attach?

From the research: The iliolumbar ligament connects the transverse process (the bony projections on either side of the vertebrae where ligaments and muscle attach themselves), of L5 to the iliac crest (uppermost part of the pelvis) and contributes to lumbosacral stability and has been associated with low back pain ( ...

Is the sacrum a joint?

The sacroiliac joints link your pelvis and lower spine. They're made up of the sacrum — the bony structure above your tailbone and below your lower vertebrae — and the top part (ilium) of your pelvis. There are sacroiliac joints in both the right and left sides of your lower back.

The supraspinous ligament or supraspinal ligament is a strong fibrous cord that connects together the apices of the spinous processes from the seventh cervical vertebra to 3rd or 4th lumbar vertebrae.

What inserts into PSIS?

As the most posterior projection of the iliac crest, it serves for the attachment of the long posterior sacroiliac ligament, which blends with the sacrotuberous ligament, as well as the multifidus and gluteus maximus muscles.
