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

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

It contains the scapular circumflex vessels.[7]

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