A Costotransverse ligament is a short fibrous band that connects a rib with the transverse process of vertebra. They are some of the ligaments that surround the costovertebral joint.

Types

There are three types of costotransverse ligaments in the human body: costo-transverse ligament; lateral costotransverse ligament; and superior costotransverse ligament. In addition, some sources also list the inferior costotransverse ligament, and the posterior costotransverse ligament in this grouping.

Functions

Support and prevent dislocation of ribs and limit the costotransverse joint to perform a gliding movement.
Their posterior surfaces provide attachment points for the extensor muscles (deep group) of the back.
