Presentation Transcript

Prevention l.jpg
Prevention

  • strength

  • flexibility

  • proper protective equipment

  • proper sport technique


Contusions neck throat l.jpg
Contusions - Neck & Throat

  • blunt trauma

    • baseball, hockey puck

  • larynx - possible fx. of cartilage

    • severe pain

    • hoarse voice

    • difficulty swallowing

  • contusion to carotid artery

    • causes a clot to form - stroke


Cervical nerve stretch syndrome l.jpg
Cervical Nerve Stretch Syndrome

  • brachial plexus injury

    • stinger, burner, hot-shots

  • 2 mechanisms

    • traction (stretch)

      • head forced one way and pain on other side

    • compression

      • entrapment or impingement of cervical nerve roots

        • at Erb’s Point


Slide5 l.jpg

  • Signs & Symptoms

    • immediate pain

    • numbness or burning sensation down arm

    • arm may be hanging at side or they may be holding it or shaking it

    • decreased strength

    • decreased sensation along dermatomes

  • s & s can last for a short period of time in mild cases, hours, or even days in severe cases


Slide6 l.jpg


Cervical nerve root impingement l.jpg
Cervical Nerve Root Impingement

  • pressure placed on a cervical nerve root

  • mechanism

    • degenerative disk changes (herniated disk)

    • dislocated cervical facets

    • degenerated facet joints

    • exostosis of vertebral foramen

    • inflammation putting pressure on nerve root

  • pressure causes pain and spasm in cervical areas and possibly pain & sensation loss along affected dermatomes, muscles weakness, altered reflexes, and atrophy


Vertebral artery compression l.jpg
Vertebral Artery Compression

  • can be caused by same mechanisms that cause cervical root symptoms

    • can interrupt blood flow to the brain

  • s & s

    • dizziness

    • confusion

    • nystagmus

  • Vertebral Artery Test


Sprains strains fx l.jpg
Sprains, Strains, Fx.

  • mechanisms of injury

    • compression force (axial force)

    • flexion force - most dangerous when combined with compression – fractures or dislocations

    • hyperextension

    • flexion rotation

    • hyperextension rotation - dislocations

    • lateral flexion


Slide10 l.jpg

  • Always assume the worst!!!!

  • spinal cord function is only inhibited by 1 of 2 mechanisms:

    • impingement or lacerations secondary to bony displacement

    • compression secondary to hemorrhage, edema, and ischemia to the cord


Slide11 l.jpg

  • Evaluation

    • don’t move!!

    • Severe neck pain

    • numbness or tingling

    • muscle weakness and spasm

    • loss of sensation - “can’t feel”

    • unable to move

    • loss of bladder or bowel control


Slide12 l.jpg

  • Other indications of serious injury:

    • Babinski Test

    • Oppenheim Test

    • Decerebrate Posture

      • lesion of brain stem

      • extension of extremities and retraction of head

    • Decorticate Posture

      • lesion of brain stem

      • flexion of elbows and wrists, clenched fists, and extension of lower extremity

    • Flexion Contracture

      • arms flexed across chest

      • spinal cord lesion at C5-C6 level


Slide16 l.jpg


Transient quadriplegia l.jpg
Transient Quadriplegia off of the field

  • athlete shows signs of quadriplegia, but symptoms clear within 15 minutes to 48 hours

  • neurapraxia of spinal cord

    • mechanism – blow to head & neck – predisposed by:

      • stenosis of spinal foramen

      • congenital fusion of spinal cervical canal

      • abnormalities of posterior arch

      • cervical instability
