    Default A Physician's Speculation on Alonso's Injury

    Neurosurgeon speculates on Alonso’s injuries

    15 G's! Some pretty sobering thoughts:

    "Over the last few days an inordinate amount of speculation has been voiced in regards Fernando Alonso’s hospitalisation following his accident during testing.

    With statements from Mclaren seemingly contradicting themselves and no official word from Alonso’s management other than short snippets of memories – it has opened up the proverbial can of worms.

    Omnicorse.it conducted an interview with Dr Nicola Acciari, a neurosurgeon from the Bellaria Hospital in Bologna who has formally helped the publication with articles in relation to the injuries suffered by Michael Schumacher and Jules Bianchi respectively.

    The accident may not have looked particularly dramatic but the FIA warning light registering an impact exceeding 15G tells us that the impact was violent and the sharp deceleration resulted in an abrupt movement of the head and neck.

    ” Of course we do not know in which direction Alonso was looking or if he maintained his head facing in that direction and it’s impossible to state whether he had tensed his muscles before the impact. But don’t forget the deceleration of the head is magnified by the weight of the helmet itself. It’s also likely that the Hans device in this particular accident was less effective than in a frontal accident.”

    “The angle of impact could have caused an intracranial cerebral concussion as the brain stem and spinal cord were stretched. His anxious state following the accident would support this. This type of injury would be sufficient to cause a state of wonderment with headaches and nausea.”

    “As to his complaints of back pain it is possible due to the stretching and angle of the spine. As the drivers shoulders are fixed so securely the neck and head are still able to move and despite there being side protection there would still be the inertia to contain.”

    “If i was the physician giving guidance to Alonso, I would suggest avoiding testing because the effect of these injuries will still be felt for some days from now. He should have further tests in 10 to 15 days time and only then can a decision be taken. The other thing to consider is that after 30 all people will begin to degenerate physiologically. I still remember seeing Nelson Piquets cervical radiograph after his accident whilst testing for the 1987 San Marino Grand Prix – and it wasn’t that of a young healthy man..”

    In the meantime, Mclaren represents that high wind was the culprit, but look at the scorch mark below:

    Fortunately, Alonso looks and sounds pretty good in his video below:

    What is the scorch mark a sign of? The engine moved over in the chassis and burnt the outer skin?

    The speculation that the accident is not the result of a driver error, but of the driver getting electrocuted by the car, losing consciousness.
    Burn marks are suspected to be a fried electrical part.
    I find it extremely hard to believe that the Alonso that practically owns this specific turn would have crashed the car right there because of the wind.

    Does anyone know if Alonso uses a different head and neck restraint system than the HANS?
    If nothing happens and there is no one around why did it not happen?

    He must be using something with Spanish name rather than German

    Your observation makes a lot of sense since this is in the area of the exhaust headers.

    Not a Honda, but still:

    The burn mark was actually later explained to be a shadow from the camera mount above.

    With this photo and passmenow's post, this seems to have been well sleuthed by our own experts.

    I'd say the "burn mark" is a reflection rather than a shadow. Same difference ultimately. But I'm anal retentive about stuff like that being an ex-3D animator for games (a long time ago).

    Here's another post crash picture. Note the sun position (not a shadow) and how the "burn mark" moves with a different camera angle. The McLaren is very reflective there.

    I'll take the winds explanation. If Alonso is on the edge and he gets a big unexpected cross gust, aero downforce gets diminished suddenly, like hitting a patch of ice he's going off track(?).

    I don't remember seeing an F1 driver wearing anything other than a HANS. As a HANS owner, I think sometimes, this has very little side impact restraint. Whereas, some other devices do. Hmmm...

    It is most definitely not a shadow of the camera. You can spot a shadow to an object that is located just outside of the picture, to the right. Shadows are moving left of their respective objects. That black mark is to the right of the camera.
    I'm going with reflection.

    F1 drivers have their side impact restraint in the form of the cockpit insert piece, that big horse shoe shape thing they take off when they get out of the car -

    Yeah, I couldn't remember how close the side bolsters are. As that picture shows they are Close. Within the range of restraint of a head/neck device with side impact capabilities, I would think.

    I was more thinking of me, as I always do (says my wife). I don't have a HALO seat in my car because it must be driven to and hopefully from the track. However, the newish Sparco Ergo seat with the removable HALO extensions is very appealing. As is Nexgen's claim of side impact restraint.

    I haven't seen the Ergo upclose, but the halo needs to be solid, not some flexy flap on the side.
    Cobra Evolution is a rather easy to live with halo seat for cars that are being driven to and from.

    The mounting system for the ERGO halo is pretty substantial. I'm not sure how practical it would be to remove and reinstall the halo.
