Intra-articular ligament of head of rib

The intra-articular ligament of head of rib is a ligament of the articulation of head of rib situated within the joint capsule. It takes the shape of a short, flat band. It joins the crest of head of rib (between the superior costal articular facet and inferior costal articular facet - thus dividing the joint cavity into two compartments ), and the intervertebral disc.   It is absent in ribs I and X-XII.
