On-scene invasive emergency procedures, such as intraosseous puncture, are often unavoidable, when indicated, and present a challenge for the emergency physician. Personal, temporal or local conditions are often unsuitable. Even with regular intervention by the emergency medical service, "last resort" measures occur very infrequently, particularly in pediatric emergencies. For the first time, this case report presents the use of intraosseous access at the humeral head with children, with reference to indication, implementation, problems and risks.
