It should not be confused with the [[triangular interval]].

==Boundaries==

It has the following boundaries:

* Inferior: the superior border of the [[teres major]];

* MedialLateral: the long head of the [[triceps]];

* Superior: Teres minor or Subscapularis

* Lateral: the humerus

For the superior border, some sources list the [[teres minor]],<ref name="isbn0-7817-5309-0"/><ref>{{SUNYAnatomyLabs|03|05|01|01}} - "Triangular Space of Scapular Region"</ref> while others list the [[subscapularis]].<ref name="isbn0-443-06612-4">{{cite book |author=Adam Mitchell; |author2=Drake, Richard; |author3=Gray, Henry David; |author4=Wayne Vogl |title=Gray's anatomy for students |publisher=Elsevier/Churchill Livingstone |___location= |year=2005 |pages= |isbn=0-443-06612-4 |oclc= |doi=}}</ref>

==Contents==

It contains the [[scapular circumflex]] vessels.<ref>{{cite journal | authorvauthors = Wasfi F, Ullah M | title = Structures passing through the triangular space of the human upper limb | journal = Acta Anat (Basel) | volume = 123 | issue = 2 | pages = 112–3 | year = 1985 | pmid = 4061026 | doi = 10.1159/000146049}}</ref>

Unlike the quadrangular space or the triangular interval, no major nerve passes through the triangular space.
