“…Head wear including a helmet or knit cap protected against serious head injuries on jumping, but whether helmet use prevents injuries in snowboarders is still controversial. Helmets may increase cervical spine injury 8) and the incidence and the severity of injuries. 7) Helmets may also restrict sight and hearing, and contribute to an increase in collisions.…”

The rate of head injury is 1.86-6 times higher for snowboarding than for skiing. Detailed data about the usefulness of a helmet or knit cap for protecting against serious head injuries have not been reported. The present study evaluated the use of a helmet or knit cap for preventing head injuries. Questionnaire data were collected from 1,190 consecutive patients in a hospital during the 1999/2000-2002/2003 winter seasons at Uonuma ski resort, Niigata, Japan. Patients were divided into the helmet, knit cap, and no cap groups. Upper technical level was highest and jumping as the cause of injury was most frequent in the helmet group. After adjustment for other confounders, there was a significant negative association between the occurrence of serious head injury during snowboarding and female sex (adjusted odds ratio 0.55, 95% confidence interval 0.421-0.718, p º 0.0001) and a significant positive association between serious head injury and jumping (adjusted odds ratio 2.25, 95% confidence interval 1.48-3.43, p ＝ 0.0001). Among snowboarding maneuvers, only jumping showed a significant negative association between wearing of a helmet or knit cap and the occurrence of serious head injury (p ＝ 0.036). Snowboarders who wear helmets might attempt dangerous maneuvers causing injuries. Wearing of a helmet or knit cap protected against serious head injuries on jumping. Every snowboarder should wear a helmet or knit cap on jumping to prevent head injury.

“…Specific types of skull base fracture, including ring (complete or incomplete) and hinge fractures, can be accompanied by brain stem injury 7) . Ring fractures that occur at the skull base involve separation of the rim of the foramen magnum from the rest of the skull, accompanied by the fracture of one petrous temporal bone to the other across the midline and then posteriorly around the foramen magnum through the occiput.…”

Due to improvements in emergency resuscitation provided by rescue teams, more trauma victims who could have died due to sudden heart failure at the scene are brought to the hospital following resuscitation. Most of these patients present with major organ injuries and hypovolemic shock at the time of trauma. However, head trauma associated with sudden heart arrest is rare. Here, we report a case of ring fracture with pontomedullary laceration that led to sudden heart arrest.

“…Skull base fracture produced antemortem is much more complex. It can be caused in situations such as, when external force acting on the ocular region causes supraorbital fracture [9]; when an external force acts directly on the head causing deformation of the skull and leading to fracture in the anterior cranial fossa [10]; or concussion of the brain leading to skull base fracture [11]. An antemortem skull base fracture can be very diffuse, usually involving the anterior, medial, and posterior cranial fossa.…”

Three cases of death are described where all the refrigerated skull of corpses showed cranial base fracture. A question arose whether these fractures were caused by head injury. As the details were clear and both autopsy and relative pathological findings displayed nothing positive, it was presumed that the cranial base fracture was due to the expansion of brain volume and increased intracranial pressure after refrigeration. And the evidence showed that the suspicious fracture was to be classified as an uncommon refrigeration-induced post-mortem artefact.

Are Fractures of the Base of the Skull Influenced by the Mass of the Protective Helmet? A Retrospective Study in Fatally Injured Motorcyclists

Abstract: In accidents with axial load shift, helmets weighing more than 1,500 grams increase the risk of a basal skull fracture. Therefore high-weight helmets should be avoided.
