POSTERIOR LONGITUDINAL LIGAMENTS Meaning and
Definition
-
The posterior longitudinal ligaments refer to a pair of fibrous bands located on the back side of the vertebral column within the spinal canal. These ligaments run along the posterior aspect of the vertebral bodies, extending from the cervical (neck) region to the sacrum (triangular bone at the base of the spine). The ligaments are situated in the midline of the spinal canal, just behind the spinal cord.
Functionally, the posterior longitudinal ligaments provide stability and support to the vertebral column, assisting in limiting excessive movement and maintaining alignment between adjacent vertebrae. They primarily serve to prevent excessive flexion (forward bending) of the spine, helping to protect the delicate spinal cord from injury and to maintain the overall integrity of the vertebral column.
Histologically, the posterior longitudinal ligaments are composed of dense fibrous connective tissue, mainly collagen fibers that are arranged longitudinally. This structure enables the ligaments to withstand tension and resist stretching forces, providing crucial support to the spine during various activities, such as bending, twisting, and weight-bearing.
Disorders or injuries affecting the posterior longitudinal ligaments can lead to conditions like spondylolisthesis (a forward slipping of one vertebra over another) or can contribute to the development of spinal instability. Understanding the importance and characteristics of the posterior longitudinal ligaments is valuable in the diagnosis and management of spinal pathologies.
