Interarticular Ligament of Head of Rib (Left)
Ligamentum intraarticulare capitis costae
Read moreStructure
The interarticular ligaments are short flat bands that attach from the crest between the articular facets (demifacets) on the heads of the ribs to the intervertebral disk. Therefore, they split the synovial joint of the head of the ribs in two. Since the 1st, 10th, 11th, and 12th ribs only articulate with the vertebral body of the same number, the interarticular ligaments are absent.
