The interspinous ligament connects each adjacent spinous process. The fibers extend from the base to the tip of each spinous process. Anteriorly, the interspinous ligament is adjacent to the ligamentum flavum; posteriorly, it is adjacent to the supraspinous ligament. in the cervical spine, the interspinous ligament becomes part of the ligamentum nuchae, a fibro-membranous ligament posteriorly and cranially to attach to the occiput.
The supraspinous ligament is a very strong band connecting the tips of contiguous spinous processes. It extends from c7 (vertebra prominens) to the sacrum. above c7 these fibers are part of the ligamentum nuchae.The ligamentum flavum, also called the yellow ligament, consists of elastic fibers oriented vertically that extend from the anterior inferior surface of the lamina above to the superior posterior surface of the lamina below. Unlike the ALL and PLL, the ligamentum flavum is not continuous. There is a small space in the midline between the right and the left fibers. The ligamentum flavum tends to thicken as it progresses down the spine, beginning at the axis (C2) and extending to the sacrum.
Lumbosacral Ligaments
The iliolumbar ligaments extend from the transverse processes of L4 and L5 to the iliac crest.
The lumbosacral ligament is a thick, fibrous band that extends from the anterior-inferior aspect of the trans-verse process of L5 to the lateral surface of the sacrum.
The are two types of SACROILIAC LIGAMENT:
- short sacroiliac ligaments: Composed of horizontal fibers extending from the sacrum to the posterior part of the iliac bone
- long sacroiliac ligaments: Composed of fibers extending vertically from the sacrum to the posterior superior iliac spine
