Costotransverse Posterior Ligament

The costorenal ligament crosses the last two ribs - XI and XII, fixing them to the posterior surface of the body X. The relative length of this ligament is very variable, so in newborns it is easily stretchable, and in adults it is relatively long (longer in men than in women). The mesentery of the spleen is directly connected

The costal-transverse posterior ligament (in n.p. - simply “costal-transverse”) connects the ribs of the same name with the transverse processes of the corresponding vertebrae and firmly secures the ribs in their normal position.

- __Anatomical features__ There are countless ligaments of the costo-lumbar and interosseous thoracic and lumbar parts of the chest wall. They stretch in all directions, both longitudinally and transversely. To a greater extent, the intercostal ligaments divide and communicate with each other, and therefore their surface area becomes even larger and allows diffusion processes to occur. In the interstitial space on each side there are clavipectoral ligaments (3-4). The lumbar sections of the spinal nerves enter the intervertebral foramina and, in connection with the fascia, form the costo-lumbar complex of the spine, which plays the main role: holding the transverse processes, forming the thoracic intestine and ribs. The fibers of the ligaments are a continuation of the paravertebral muscles, and its fibers pass under the bone and cartilaginous plates of the ribs.

So, the costotransverse posterior ligament - (l. Costotransversaria Posterior) - is a paired ligament covering the back of the spinal column and the anterior angle of the scapula at the shoulder joint. Located between the two lumbar vertebrae. It extends across the axis of the scapula, connecting the humerus and sternum on one side and the humeral process of the scapula on the other. It is a combination of the rhomboid ligament (m. rombi lateralis) and the radiate ligament of the scapula (l. lunata). In children, heterochronic ossification sometimes occurs in this place, as a result of which the sternum is divided by the transverse bone into two plates. It prevents the sternum from descending downward and participates in the formation of the posterior wall of the chest cavity.

The costo-transverse-posterior ligament is a fairly large ligament formation. Together with the shells, it makes up about 80% of the entire area of ​​the indicated part of the back. Most of this ligament is located in front of the spinal cord and is fibrous tissue. Approaching the base of the spine, it is divided into several thin white bridges: two of them run along the spinal cord, the third connects to the sternal sac, which gives it strength and makes it part of the protection of important organs located in the upper part and some surfaces around. The neurovascular plexus is also formed by rib ligaments - posterior transverse, anterior transverse and anterior transverse ligaments. Together they protect and guide important blood and nerve pathways, leaving only a small gap around which the nerve can easily become trapped. Thus, the transverse posterior costal ligament has a unique structure that supports important structures.

The ligament has the largest diameter in the transition zone from the lower to the upper section - 23 mm. In the area of ​​the roots of the ribs it is thickest - the diameter can reach 30 mm on the sides and 25 mm closer to the middle. The front retains a thickness of up to 9 mm. In addition, there is a gap formed by the vertebral joint. The depth of the rear part reaches 40 mm, in the front – 14 mm. The average width is approximately 65 mm, the top can expand up to 74 mm according to this indicator.

The anterior part of the ligament is attached to the tubercle of the anterior surface of the first rib and the external spinous processes of the two adjacent underlying vertebrae. At the same time, the posterior section is attached to the apices of the transverse processes of the first two parietal vertebrae and the tubercles of the four thoracic segments following them. The coverage of the entire spinal column at the base of the neck reaches 46 mm, and above it this figure corresponds to 90 mm.

Introduction The rib ligament and transverse posterior ligament are important elements of the human skeletal apparatus. If these ligaments are damaged, it is possible that instability will develop in the area of ​​the injured segment, which can lead to disruption of the entire body.

The costal-transverse posterior ligament The costal-transverse posterior ligament is a fairly large ligamentous cord that is part of the posterior part of the chest skeleton. This ligament connects the cartilaginous ribs of the right and left hemispheres of the chest, helping to keep them in a relatively stable position in relation to each other and the body.

The ligamentous cord is located on the side of the spinal column. The ligament is placed in the area of ​​the thoracolumbar joint. The length of this ligament is 9-12 centimeters. Sometimes the cords can be mild in some patients. These areas can be torn even with minor traumatic impacts. It is also called the lateral arcuate ligament or simply the arcuate ligament. This ligament is also called the paired intercostal connection of the anterior part of the ribs and the vertebrae themselves and helps to withstand the load during body movement. Since the chest bends backward, this ligament takes on part of the load at this time and ensures a stable position of the ribs. Due to its elasticity, elasticity
