Arrow EZ-IO Proximal Humerus Identification & Insertion Technique – Adult Identify the proximal humerus: Using either method below, adduct elbow, rotate humerus internally: 1. Place the patient's hand over the abdomen with arm tight to the body 2. Place the arm tight against the body, rotate the hand so the palm is facing outward, thumb pointing down Place your palm on the patient's shoulder anteriorly. • The area that feels like a "ball" under your palm is the general target area • You should be able to feel this ball, even on obese patients, by pushing deeply Place the ulnar aspect of your hand vertically over the axilla. Place the ulnar aspect of your other hand along the midline of the upper arm laterally. Place your thumbs together over the arm. • This identifies the vertical line of insertion on the proximal humerus. Palpate deeply up the humerus to the surgical neck. • It will feel like a golf ball on a tee – the spot where the "ball" meets the "tee" is the surgical neck. • The insertion site is 1–2cm above the surgical neck, on the most prominent aspect of the greater tubercle.
