Scope. Our paper proposes to establish the hierarchy of the physiopathological cascade affecting the brain in implosive manner due to strong blows on forehead during contact sports. So, we imagined an original model of head functional organization that actively integrate the bone structures and soft epicranial and endocranial parts, the last ones consisting of leptomeningeal, cerebrospinal fluid and brain tissues in order to develop adequate mesures of primary aid. Materials and Methods. We have studied vast osteological and imagistical material, in conjunction with anatomical data on the brain in situ, on fixed preparations or in vivo CT and MRI sections for a dynamic assessment of the studied structures. Results and Discussion. The primary results refer to the resistance structures of the forehead where we have demonstrated an original model of force lines transmitting the shock of the blow from bony forehead to the brain. The data obtained on dry skulls were confirmed on CT and MRI sections through the cephalic extremity in patients without neurological disorders. The results will be presented and discussed in the caudocranial order of impact energy propagation through affected structures, id est from face to the brain. Conclusions. In the contact sports, the strong forehead blows could produce loss of consciousness, technically called knock out, that medically belongs to the large category of sincopa. Our study demonstrated that the shock on forehead activates numerous collateral mechanisms that must be considered when the first aid is applied. So, our cascade model consist of an initial shock/contrasock brain disturbance, called conccusion followed by cerebrospinal liquid movement through the ventricular system towards vital centers area postrema and vagal dorsal nucleus, inducing cardiovascular depression. Concomitently, the lateral torsion of the head straches vertebral artery and induces brain stem ischemia and also straches the carotid sheath with depresor vagal effects. |
