Zusammenfassung

Penetrierende Verletzungen des Gehirnschädels werden überwiegend als Schussfolgen beobachtet. Zu den möglichen Ursachen zählen auch die baugewerblich verwendeten Bolzensetzgeräte und Nagelschussapparate. Die daraus verschossenen Schrauben und Nägel können im Fall eines Freiflugs selbst knöcherne Strukturen durchdringen. Berichtet wird über die konsiliarische rechtsmedizinische Beurteilung eines 22 Monate alten Jungen, der wegen einer penetrierenden Kopfverletzung in eine Notfallambulanz gebracht worden war. Die Eltern gaben an, das Kind habe sich die Verletzung bei einem Sturz vom Dreirad zugezogen. In der Stirnhaut steckte der Kopf einer Nagelschraube, die 4,5 cm tief ins Schädelinnere ragte. Die Gesamtheit der berichteten Umstände und der medizinischen Befunde sprach dafür, dass der Junge unfallmäßig von einer frei fliegenden Nagelschraube aus einem baugewerblichen Schussapparat getroffen wurde. Der intrakranielle Fremdkörper wurde entfernt; der postoperative Heilungsverlauf war komplikationslos.

Abstract

Penetrating injuries to the skull are mainly seen in gunshot injuries but can also be caused by powder-actuated tools and nail guns used in the construction industry. They fire screws and nails which reach a high kinetic energy and can even perforate bony structures if they have a free flight. The presented case deals with a 22-month-old boy who was taken to an emergency department with a penetrating injury to the head. According to the parents the child sustained the injury in a fall from a tricycle. The head of a nail which had penetrated the skull to a depth of 4.5 cm was found in the skin of the forehead. The circumstances of the incident and the medical findings suggested that the boy had been accidentally hit by a free flying nail from an industrial nail gun. The intracranial foreign body was removed and the postoperative clinical course was uneventful.
