Brain Injury Patterns in Fatally Injured Pedestrians

Temporal bone fractures: sequelae and their impact on quality of life

“…In 3 cases with immediate and grade V-VI FP, facial nerve decompression was performed within an average of 15 days after trauma (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). In one case of otic capsule sparing and longitudinal fracture, decompression was carried out by the subpetrous approach, and compressive hematoma of the geniculate ganglion was discovered.…”

“…Recent publications have reported their importance [2,18,19]. The brain is most likely to suffer injury due to lateral impacts as opposed to posterior or frontal blows [20]. Asha'Ari et al [18] reported that temporal bone fractures were significantly associated with the presence of intracranial injuries.…”

Kafa Travmalarında Diffüz Akson Zararı Tanıda B-App’nin Yeri

“…Bu travma tipleri bafll›ca araç içi trafik kazalar› ve yük-sekten düflmelerdir (17). Bunlar d›fl›nda sald›r› olaylar›, h›rpalanm›fl çocuk sendromu, basit düflmeler gibi kafan›n ani akselerasyonuna yol açan travma türlerinde de benzer mekanizmalarla akson yaralanmalar› görülebil-mektedir (17)(18)(19)(20)(21). Adli otopsilerde bu mekanizmalar›n olay›n öyküsü, olay yeri incelemesi ve otopsi bulgular›y-la birlikte yorumlanmas› sonucunda olay›n gerçek olufl biçiminin tan›mlanmas› mümkün olabilecektir (12).…”

Bicycle helmets and brain injury

“…Transfer of energy rather than angular momentum is wrongly emphasised as a cause of brain injury (Holbourn, 1943). Linear acceleration is proposed as an important cause merely because a positive relationship was found between it, as estimated from occipital impacts, and severity of brain injury (Ryan et al, 1994), but this finding depends on an assumption that the force vector was normal to the surface of the skull. Any offset would generate angular acceleration, which could well have caused the brain injuries observed; indeed, the details of them suggest it.…”
