What vertebral level is the angle of Louis?
It is at the level of the T4-T5 intervertebral disc. It marks the level of the transverse thoracic plane which divides the mediastinum into the superior and inferior mediastinum.
Which level is sternal angle of Louis is located at?
The sternal angle (of Louis) is the angle between the manubrium and body of the sternum it is located 5 cm inferior to jugular notch at the level of the 2nd costal cartilage; thus, it is a useful landmark for rib counting since the first rib is difficult to feel.
Where does the sternal angle lie?
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.
Is sternal notch the angle of Louis?
The sternal angle (also known as the angle of Louis, angle of Ludovic or manubriosternal junction) is the synarthrotic joint formed by the articulation of the manubrium and the body of the sternum….

Who is the sternal angle of Louis named after?
1 This anatomic landmark is named after the French surgeon Antoine Louis (1723–1792). Since then, the medical literature has variously described this landmark as the Angle of Louis, Lewis, and Ludwig.
What vertebral level is sternal angle?
Anatomy. 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 vertebral level is the sternal angle?
What level is the sternal notch?
As the level of sternal notch is found to be present below the level of T2 and T3 radiologically in most cases, a low cervical approach can be contemplated in most patients with upper thoracic spine pathology depend- ing on their sternal level as determined by preoperative radiographs.
Why is the sternal angle called the angle of Louis?
What is behind angle of Louis?
Why is it called angle of Louis?
Where is the sternal angle of Louis located?
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. Click to see full answer In this regard, where is the angle of Louis located?
What’s the average angle of the Louis joint?
In a cadaveric study of preserved skeletal specimens, the sternal angle ranged from 149.0 degrees to 177.0 degrees with an average of 163.4 degrees in men and 165.0 degrees in women. [5] A small amount of movement in the angle of Louis does occur, particularly in younger people where the fibrous joint features increased flexibility.
What does the sternal angle of a male mean?
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.
Is the sternal angle at the T4 level?
Anatomy. In clinical applications, the sternal angle can be palpated at the T4 vertebral level. The sternal angle is used in the definition of the thoracic plane. This marks the level of a number of other anatomical structures:
