The intertransverse ligaments are weak, sheet-like^[1] ligaments interconnecting adjacent transverse processes in the thoracic spine, and adjacent accessory processes in the lumbar spine. They act to limit lateral flexion and rotation of the spine.^[2]

In the cervical region, they consist of a few irregular fibers that are largely replaced by the intertransversarii.^[3] In the thoracic region, they are rounded cords intimately connected with the deep muscles of the back.^[4] In the lumbar, region they are thin and membranous.^[3]

The intertransverse ligaments often blend with the intertransverse muscles.^{[5][citation needed]}
