The costovertebral joint represents a complex articulation between ribs and vertebrae, essential for respiratory mechanics and thoracic cage stability. This specialized joint system combines multiple ligamentous attachments with precise articular surfaces to enable coordinated rib movement during breathing while maintaining structural integrity of the thoracic spine.
Anterior costotransverse ligament divided The anterior costotransverse ligament connects the anterior aspect of the transverse process to the rib neck. This strong ligamentous structure provides stability while allowing controlled rib movement during respiration.
Ligament of the neck The ligament of the neck attaches to the superior surface of the rib neck. It works in conjunction with other ligamentous structures to maintain joint stability during respiratory movements.

Ligament of the tubercle The ligament of the tubercle connects the rib tubercle to the transverse process. This ligament provides additional stability to the costotransverse joint while allowing necessary movement.
Articular capsule The articular capsule encloses the costovertebral joint space. It contains synovial membrane and fluid, facilitating smooth articular movement while maintaining joint integrity.
Transverse Section of Intervertebral Fibro-cart The intervertebral fibrocartilage provides cushioning between vertebral segments. Its unique structure allows for even distribution of forces while maintaining spinal flexibility.
Synovial cavity The synovial cavity contains specialized fluid that enables smooth joint movement. This cavity is essential for proper joint function and nutrition of the articular surfaces.

Costovertebral Joint Biomechanics
The costovertebral articulation demonstrates remarkable mechanical complexity. This joint system enables precise rib movement during respiration while maintaining thoracic stability. Understanding these mechanics is crucial for diagnosing and treating thoracic conditions.
Functional Anatomy
The joint’s design incorporates multiple elements working in concert. Each component contributes to both mobility and stability, creating a system that balances these competing demands during respiratory cycles.
