The triangular space (also known as the medial triangular space,[1] upper triangular space,[2] medial axillary space or foramen omotricipitale[3]) is one of the three spaces found at the axillary space. The other two spaces are the quadrangular space and the triangular interval.[4]
Boundaries
[edit | edit source]It has the following boundaries:
- Inferior: the superior border of the teres major;
- Lateral: the long head of the triceps;
- Superior: Teres minor
For the superior border, some sources list the teres minor,[2][5] while others list the subscapularis.[6]
Contents
[edit | edit source]It contains the scapular circumflex vessels.[7]
Unlike the quadrangular space or the triangular interval, no major nerve passes through the triangular space.
