  • neck and spine injury data

    I am a graduate student at the Colorado School of Mines and I am
    studying neck injuries, specifically in football players. I am trying
    to analyze what sort of forces are exerted on the spine via the head,
    and what will determine a fracture in the spine. Obviously, if there
    is a direct downward impact on the top of the head you are more likely
    to suffer a fracture in the cervical spine than if the impact was
    directed perpendicular to the face. I am trying to find data that
    shows the amount of force that will cause a fracture in the spine from
    axial impact. I found some data from an experiment that was done on
    some University of North Carolina football players. They wore helmets
    with accelerometers in them and they were able show how much force the
    head sustained during both practices and games. Some of the players
    had over 200 g's of force in their heads which is very large. This
    data should be pretty helpful. I also found some information in the
    Biomch-L archives from a post on December 6,2001 about neck injuries.
    A reference was given about spinal injuries with vertical impact
    (Sances et al. (1986) Spinal Injuries with
    Vertical Impact, in Mechanisms of Head and Spine Trauma, Eds, Sances,
    Thomas, Ewing, Larson, Unterharnscheidt, Aloray Publisher, pp.305-308
    describes vertical (head-down) dropping of cadavers.) This article
    looks like it would be very helpful, but I do not have access to it
    (at least not free access) so I would like to request a copy of it if
    at all possible. Lastly, I was wondering if there were some simulators
    that would be useful to collect data from. I tried to find some free
    spine simulators where you could apply a few loads the head/spine and
    reover some data from it but was unsuccessful. I am wondering what
    sort of programs are out there and whether or not they would be useful
    to collect data from. Thank you so much for your time and response.
