Anatomical space in the shoulder region

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.

-'''Triangular space''' is a region in the [[axilla]], or armpit area, of the human body. It is one of three spaces in the axilla, the other two being the [[quadrangular space]] and the [[triangular interval]]. The triangular space is bordered by the [[teres major muscle]], the [[teres minor muscle]], and the long head of the [[triceps brachii muscle]].

-Due to the passage of the circumflex scapular artery through the triangular space, injury to this area can lead to significant bleeding. Furthermore, the close proximity of the triangular space to the [[brachial plexus]] and [[axillary artery]] means that injury to this area can also result in nerve damage and further vascular injury.
