Clinical correlation

Triangle of auscultation

Next to the inferior angle of the scapula there is a small triangular gap in the musculature, between the superior border of the latissimus dorsi, the medial border of the scapula and the inferolateral border of the trapezius. Here the posterior segments of the lung are heard well. The triangle enlarges if the person folds the arms across the chest (bringing the scapulae forward) and flexes the trunk.
