The sternal angle corresponds to the level of the 2nd costal cartilage on either side, and the level between the fourth and fifth thoracic vertebra. The sternal angle is used to define the transverse thoracic plane which represents the imaginary boundary between the …

Feb 28, 2024 · The sternal angle is an easily palpable and often visible landmark on the anterior chest wall and as it marks the level of the second costal cartilage, it is commonly used by clinicians during physical examinations for identifying and counting ribs.

Dec 13, 2020 · The sternal angle is the angle formed between the manubrium of the sternum and the body of the sternum (manubriosternal junction), and is an important anatomical landmark. It marks the level of the 2nd pair of costal cartilages which lies at the level of the intervertebral disc between thoracic vertebrae 4 and 5.

Dec 10, 2023 · The sternal angle lies at the T4 to T5 intervertebral (IV) disk level. The manubrium and sternal body lie in different planes; hence, the angulation at the manubriosternal joint. The 2nd costal cartilage articulates with the lateral border of the joint.

Nov 19, 2020 · Inferiorly, the manubrium articulates with the body of the sternum, forming the sternal angle. This can be felt as a transverse ridge of bone on the anterior aspect of the sternum. The sternal angle is commonly used as an aid to count ribs, as it …

The sternal angle marks out the inferior border of the superior mediastinum and is located at the level of the intervertebral disc between T4 – T5. The 2nd rib combines with the sternum at the sternal angle, and makes it an important site for determining rib number.

Jan 31, 2025 · The sternal angle, also known as the angle of Louis, is a palpable bony prominence at the junction between the manubrium and the body of the sternum. It is located at the level of the second costal cartilage and is an important anatomical landmark for clinicians.

The sternal angle passed through T2-T3 intervertebral disc in 80 cases (40%) and other level in 120 cases (60%) (Figure 4). T2-T3 level is the commonest vertebral level of sternal notch in our study.

The sternal angle (angle of Louis) is the anterior angle formed by the junction of the manubrium and the body of the sternum which varies around 162 degrees in males. The sternal angle is a palpable clinical landmark under the skin that marks a number of other features: Boundary between the superior and inferior portion of the mediastinum

The sternal angle marks the approximate level of the 2nd pair of costal cartilages, which attach to the second ribs, and the level of the intervertebral disc between T4 and T5. The sternal angle can be palpated at the T4 vertebral level.
