Anatomical terminology [edit on Wikidata]

A superior costotransverse ligament is a ligament of the costotransverse joint that attaches onto the crest of the neck of a rib, and onto the transverse process of the vertebra superior to the rib.[1][2]

The ligament may be subdivided into a strong anterior costotransverse ligament, and a weak posterior costotransverse ligament.[1]

The ligament is absent in the first rib.[2]

Structure

The superior costotransverse ligament is a strong,[3]^[better source needed] broad fibrous band.[1]

It comprises two layers:[2]

• The anterior layer attaches at the crest of the neck of rib, and at the inferior aspect of the transverse process of the above vertebra.[2] It extends obliquely superolaterally from the rib to the vertebra.[3]^[better source needed] The intercostal nerve and vessels pass across the anterior layer.[2]
• The posterior layer attaches at the posterior aspect of the neck of rib, and (the inferior border of[3]^[better source needed]) the transverse process of the above vertebra. It extends superomedially from the rib to the vertebra. It blends laterally with the external intercostal muscle.[2]
