CHAPTER 41 • CERVICAL SPINE 247

PREVENTION



  • Reductions in the numbers of cervical spine injuries
    in sport can be made by the following:

    1. Rule changes: In the National Football League, for
      instance, rule changes in 1976 eliminated the head
      as an initial contact area for blocking and tackling.
      Coaches are encouraged to instruct players to
      block and tackle with their head up. Spearing with
      the head has been banned.
      2. Conditioning exercises to strengthen the neck and
      sports-specific training.
      3. Prohibiting spearing or tackling using the head as
      a battering ram or grabbing the facemask.
      4. Strict enforcement of the rules by officials and
      intolerance of illegal play.
      5. Understand that football players playing defensive
      positions are more likely to sustain a catastrophic
      injury, so safe blocking and tackling techniques
      should be reinforced and stressed.
      6. Ensure that equipment properly fits.
      7. Expert on-site medical care. A certified athletic
      trainer, and if possible, a sports medicine physician
      should be available at the playing field. A plan for
      managing a catastrophic neck injury must be
      rehearsed and be in place.
      8. Any athlete with a suspected head or neck injury
      should be managed as if they have an unstable cer-
      vical spine fracture until proven otherwise. The
      player should be instructed not to move, the head
      and neck should be immobilized, and trained pro-
      fessionals should coordinate safe transfer onto a
      spine board and referral to a trauma center.
      9. When possible identifying congenital anomalies of
      the spine through a thorough preparticipation his-
      tory and physical examination.
