The acromion is a reference of bone structure.
The acromion is an apophasis of the scapula, with which the external extremity of the clavicle articulates.
An apophasis is a protruding part of a bone, which serves for its articulation. The acromion is part of the shoulder joint and is its most prominent part.
Due to its almost subcutaneous anatomical situation, it is easy to locate it visually. In case of difficulty, it is easy to find it by palpation. We will ask the subject to perform a flexion and extension movement of the shoulder: by placing a finger on the tip, we will feel a displacement in the area where we will be able to find the anterior surface of the acromion.
