Medial triangular space

Last revised by Nicholas Robert Watson on 7 Sep 2022

The medial (or upper) triangular space is a communication between the axilla and the posterior scapula region. It should not be confused with the similarly named lateral (lower) triangular space.

Gross anatomy

It is a medially pointing triangle with a base laterally and apex inferomedially.
