90° elbow flexion and positioning of the arm in the measuring device (A,B) The model of a skeleton is used to illustrate the positioning of the bones of the forearm. A spirit level was installed on the linear ultrasound probe (C). Sonographic picture of the sulcus bicipitis in a horizontal alignment (D). Humeral torsion value was read on the angular degree measuring device (A,B)
