Costovertebral joints and ligaments
Other Terms: Costovertebral ligaments
The costovertebral joints form two planar joints between the vertebral end of a rib and the bodies and a transverse process of neighboring thoracic vertebrae . The joint of the costal head occurs where the head of a rib articulates in the demifacets of neighboring vertebrae. Strong ligaments bind this joint to limit movements to slight gliding motions of the head on the body of the vertebrae. The costotransverse joint forms where the costal tubercle articulates with the transverse process of the corresponding vertebra. Strong ligaments between the neck of the rib and the transverse process of the vertebra limit the movements at this joint to simple rotational and sliding motions.
