The quadrangular space (also known as the quadrilateral space) is an anatomic interval formed by the shaft of the humerus laterally, the long head of the triceps medially, the teres minor muscle superiorly, and the teres major muscle inferiorly.Click to see full answer. Similarly, what muscles make up the quadrangular space?Muscles. Three muscles directly comprise the quadrangular space; the teres minor, teres major, and long head of the triceps brachii.Furthermore, which nerve passes through the quadrangular space? axillary nerve Likewise, people ask, what makes up the triangular space? It has the following boundaries: Inferior: the superior border of the teres major; Lateral: the long head of the triceps; Superior: Teres minor or Subscapularis.What causes quadrilateral space syndrome?Quadrilateral space syndrome (QSS) is a rare condition in which the posterior humeral circumflex artery and the axillary nerve are entrapped within the quadrilateral space. The main causes of the entrapment are abnormal fibrous bands and hypertrophy of the muscular boundaries.
