The important ligamentous structures of the lower cervical, thoracic, and lumbar spine are discussed below.
The ANTERIOR LONGITUDINAL Ligament (ALL) is composed of thick, longitudinally oriented fibers extending from the axis (C2) anteriorly to the sacrum. The ALL is broader at the level of each vertebral body than at the level of the discs where the fibers adhere to the annulus fibrosus. The ALL attaches to each vertebral body superiorly and inferiorly at the levels of the endplates.
The Intertransverse Ligaments extend from the inferior surface of the entire length of the transverse process to the superior surface of the adjacent transverse process.
The Costalligaments connect the heads of the ribs to the vertebrae.
The POSTERIOR LONGITUDINAL LIGAMENT (PLL) is weaker than the ALL. Its fibers are also longitudinally oriented, but are less dense. It runs from the axis (C2) caudally to the sacrum. The PLL is narrow at the levels of the vertebrae, but the fibers extend laterally at the disc levels. These fibers may help to contain herniated disc material. Like the ALL, the PLL is attached to the vertebra at the superior and inferior margins, and to the annular fibers of the intervertebral disc.
