Interspinous ligament is a crucial component of our spinal architecture, and it serves to bind our vertebrae together. Some synonyms for this fibrous structure include ligamentum interspinale, the ligament between the spinous processes, and ligamentum superius nuchae. Interspinous ligament appears in numerous regions of the spine, including the cervical, thoracic, and lumbar segments, and it typically links to the spinous processes in these areas. The functions of the interspinous ligament include providing stability to the spinal column, limiting excessive movement of vertebral bodies, and extending support to the surrounding muscles, tendons, and ligaments. Due to its importance, any injury or damage to the interspinous ligament could significantly affect our mobility, putting us at risk of back pain and other related spinal issues.
