Triangular space[edit]
The triangular space is an anatomical region located in the shoulder area. It is one of the three spaces found in the axillary region, the others being the quadrangular space and the triangular interval. The triangular space is clinically significant as it contains important neurovascular structures.
Boundaries[edit]
The triangular space is defined by the following boundaries:
- Superiorly: The inferior border of the teres minor muscle.
- Inferiorly: The superior border of the teres major muscle.
- Laterally: The long head of the triceps brachii muscle.
Contents[edit]
The triangular space contains the following structures:
- The circumflex scapular artery, which is a branch of the subscapular artery.
Clinical significance[edit]
The triangular space is important in surgical procedures involving the shoulder, as it provides a pathway for the circumflex scapular artery. Injury or compression of this artery can lead to compromised blood supply to the scapular region.
