What is quadrilateral space syndrome?
Quadrilateral space syndrome (QSS) is a rare disorder characterized by axillary nerve and posterior humeral circumflex artery (PHCA) compression within the quadrilateral space. Impingement is most frequently due to trauma, fibrous bands, or hypertrophy of one of the muscular borders.Click to see full answer.

Quadrilateral space syndrome (QSS) is a rare disorder characterized by axillary nerve and posterior humeral circumflex artery (PHCA) compression within the quadrilateral space. Impingement is most frequently due to trauma, fibrous bands, or hypertrophy of one of the muscular borders.Click to see full answer. Similarly, it is asked, what is the quadrilateral space?The quadrangular space (or quadrilateral space [of Velpeau] or foramen humerotricipitale) is one of the three spaces in the axillary space. The other two spaces are: triangular space and triangular interval.One may also ask, what goes through the quadrangular space? The axillary nerve and the posterior humeral circumflex artery pass through this space from anterior to posterior. The triangular space is an anatomic interval medial to the quadrangular space. Its borders are formed by the long head of the triceps laterally, the teres minor superiorly, and the teres major inferiorly. Furthermore, where is the quadrilateral space? The quadrangular space (or quadrilateral space) is one of three spaces located in the posterior compartment of the arm, along with the lateral triangular space and medial triangular space.Where is the axillary nerve located?In the axilla, the axillary nerve is located posterior to the axillary artery and anterior to the subscapularis muscle. It exits the axilla at the inferior border of subscapularis via the quadrangular space, often accompanied by the posterior circumflex humeral artery and vein.
