What is the plane of the sternal angle?

The thoracic plane, also known as the transthoracic plane or the plane of Ludwig is an artificial horizontal plane used to divide the mediastinum into the superior mediastinum

superior mediastinum
Superior mediastinum is an artificially divided wedge-shaped compartment of the mediastinum located between the thoracic plane inferiorly and the thoracic inlet superiorly. The inferior mediastinum, comprising of the anterior, middle and posterior parts, lies inferiorly.

Where is the sternal angle?

The sternal angle, which varies around 162 degrees in males, 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. In clinical applications, the sternal angle can be palpated at the T4 vertebral level.

What is the level of Carina?

The carina represents the inferior termination of the trachea into the right and left main bronchi. The carina usually sits at the level of the sternal angle and the T4/T5 vertebral level in the thoracic plane.

Why sternal angle is important?

Clinical Significance

The sternal angle is an important clinical landmark for identifying many other anatomical points: It marks the point at which the costal cartilages of the second rib articulate with the sternum. This is particularly useful when counting ribs to identify landmarks as rib one is often impalpable.

What is the Manubrium?

The manubrium is the most massive, thickest, and squarest of three main sternal elements. It is the superior-most element of the sternum and is the widest part of this bone. b. Clavicular notches occupy the superior corners of the sternum. It is here that the manubrium articulates with the right and left clavicles.

Where is the true ribs?

Where is your second rib?

The second rib attaches to the sternum at the sternal angle. Since the first rib is hidden behind the clavicle, the second rib is the highest rib that can be identified by palpation. Thus, the sternal angle and second rib are important landmarks for the identification and counting of the lower ribs.

How do I identify my carina?

Traditionally, the carina has been located by the radiologist either by taking the position as the middle of the T4-T5 interspace; or by using the Dee Method, which involves identifying the aortic arch and then drawing a line inferomedially through the middle of the arch at a 45-degree angle to the midline.Nov 25, 2018
