A costotransverse ligament is ligament of the costotransverse joint which attaches at (the posterior aspect of[1]) the neck of a rib, and at (the anterior aspect of) the transverse process of its corresponding vertebra. It extends posteriorly from the rib to the vertebra.
It strengthens the costotransverse joint anteriorly.[2]
It is diminished or absent at the joints of ribs XI-XII.
