Supraspinous ligament
The supraspinous ligament is a cord-like fibrous band that runs along and connects the apices of the spinous processes from vertebrae C7 to L3/L4.
Superiorly, from vertebra C7 to the skull, specifically the external occipital protuberance, it continues as the nuchal ligament of the cervical region.
Inferiorly, in the lumbar region, it becomes thicker and broader and merges with the thoracolumbar fascia.
Anteriorly, the supraspinous ligament merges with the interspinous ligament. Posteriorly, it blends with myofascial structures.
The supraspinous ligament functions to prevent separation of the spinous processes during flexion and resists hyperflexion of the spine. Additionally, it helps maintain the upright position of the head along with other ligaments of the vertebral column.
