Costovertebral joints
(Redirected from Intra-articular ligament of head of rib)
The costovertebral joints are a set of synovial plane joints that connect the ribs to the vertebral column. These joints play a crucial role in the mechanics of breathing by allowing the ribs to move during inspiration and expiration.
Anatomy[edit | edit source]
The costovertebral joints are composed of two main articulations:
Costocorporeal joints[edit | edit source]
The costocorporeal joints are formed between the head of the rib and the bodies of the adjacent vertebrae. Each rib typically articulates with the inferior costal facet of the vertebra above and the superior costal facet of the vertebra below. The joint is stabilized by the radiate ligament of the head of the rib, which attaches the head of the rib to the vertebral bodies and the intervertebral disc.
Costotransverse joints[edit | edit source]
The costotransverse joints are formed between the tubercle of the rib and the transverse process of the corresponding vertebra. These joints are supported by several ligaments, including the superior costotransverse ligament, the lateral costotransverse ligament, and the costotransverse ligament.
Function[edit | edit source]
The primary function of the costovertebral joints is to facilitate the movement of the ribs during respiration. The joints allow for the elevation and depression of the ribs, which increases and decreases the volume of the thoracic cavity, respectively. This movement is essential for effective ventilation.
Clinical significance[edit | edit source]
Disorders of the costovertebral joints can lead to pain and restricted movement. Conditions such as costovertebral joint dysfunction or inflammation can result in thoracic pain and may affect breathing. Treatment may involve physical therapy, medication, or in some cases, interventional procedures.
