Humeral Intraosseous – Stay In & Stay Straight

This video shows the mechanism for dislodgement and deformation of humeral intraosseous needles and how to avoid this.

In summary, if you need to abduct the arm (eg. for thoracostomy), keep the thumbs down (ie. have the arm internally rotated at the shoulder). Otherwise the IO catheter may bend or fall out.
