Transcript Injuries to the Head and Spine

Injuries to the Head and Spine
The Head
• Head
– Bones of the
• cranium
• face
• teeth
– Brain
– Brain Stem
Bones of the Cranium and Face
Nervous System
• Main components
– Brain
– Cranial Nerves
– Spinal Cord
– Spinal Nerves
– Peripheral Nerves
The Nervous System
• Function
– communicate, coordinate,
regulate
• 2 main divisions
1. Central Nervous System
(CNS)
– brain, cranial nerves & spinal
cord
2. Peripheral Nervous System
– everything outside brain &
spinal cord
– gathers and carries info to and
from the CNS
Cranial Nerves
• Cranial Nerves
– 12 pairs of nerves
– lead from brain to
parts of head, neck
and torso
– involved in
• senses
• controlling facial
muscles
• regulate glands
The Nervous System
2 Types of Neurons
– Afferent Neurons (sensory)
• Sends sensory info to CNS
– Efferent Neurons (motor)
• Sends info from CNS
• Stimulates muscle tissue
• Stimulates organs and glands
– Mixed Neurons (sensory and
motor)
• Located in the brain and spinal
cord
Neurons
Major Spinal Nerves
Cervical
– C1 through C8
– Includes Brachial plexus (C5 – T1)
– Phrenic Nerve (breathing)
Thoracic
– T1 through T12
Lumbar
– L1 through L4
Sacral
– L4 through S4
– Sciatic Nerve
Spinal Nerve Roots
The Brain
Parts of the brain
– Cerebrum
• largest part (2 hemispheres)
• 4 lobes
• controls willful actions,
interprets sensory messages
• governs thought and speech
– Cerebellum
• Muscle coordination and
maintains balance
Lobes of the Brain
• Frontal
– thinking, personality,
behavior
• Parietal
– language
• Occipital
– vision
• Temporal
– language, hearing
The Brain
• Brain stem
– Connects spinal cord with
cerebrum
– Controls
• Involuntary autonomic
functions
• Breathing, heart rate, blood
pressure, digestion
– Consists of:
• Midbrain
• Pons
• Medulla Oblongata
The Brain
• Brain Stem
– Pons
• communication and
coordination center
between parts of brain
• “switchboard”
– Medulla Oblongata
• controls breathing, HR,
swallowing ect…..
The Brain
• Parts of the brain
– Hypothalamus
• Regulates body temp,
sleep cycles
• controls production of
many hormones
• body’s thermostat
Regions of the Brain
Cranial Nerves
• The 12 Cranial
Nerves
• Assessing Cranial
Nerves
Injuries to the Brain: Concussion
• Concussion
– injury to the brain or
spinal cord
• MOI
– blow to the head or a fall
• Symptoms
–
–
–
–
–
–
Dizziness
Nausea
Confusion
Headache
Disorientation
Blurred vision
Treatment of Concussions
• Treatment of concussions
– Threw out grading system
– If symptomatic, athlete has
a concussion
– No activity until
asymptomatic for 24 hours
– More severe symptoms
requires no tv, no reading,
no video games
• What is a
concussion?
Concussion: Return to Play
• No symptoms for 24
hours then:
– Day 1 – slow jog; no
symptoms, then
– Day 2 – sprints/weights; no
symptoms, then
– Day 3 – practice/no
contact; no symptoms, then
– Return to physician for
clearance
– Football High
– League of Denial: The
NFL’s Concussion Crisis
Concussions
• Second Impact
Syndrome (SIS)
– Swelling of the brain
– Occurs when suffering
2nd concussion before
1st concussion is
healed
– Very dangerous and
sometimes fatal
– E:60 - Second Impact
Syndrome
Anatomy of the Ear
Injuries to the Ear
Cauliflower Ear (Hematoma Auris)
– most common injury of ear
(wrestling)
– caused by extreme friction or
repeated trauma
– fluid and blood accumulate
around outer ear
– treat: ice and compress
Cauliflower Ear
Injuries to the Ear
Swimmer’s Ear (Otitis Externa)
– infection of ear canal
– caused by trapped
moisture
– symptoms: dizziness,
pain, itching, discharge
– send to physician
Injuries to the Ear
• Tympanic Membrane
(eardrum) Rupture
– caused by sudden
change in pressure or
objects inserted too far
– symptoms: loud pop,
pain, hearing loss
– send to physician
immediately
Tympanic Membrane Rupture
Anatomy of the Eye
Injuries to the Eye
• Contusions (black eyes)
– caused by blow to eye
area
– ice immediately
– send to physician if
bleeding or double vision
Injuries to the Eyes
Corneal Abrasions or Laceration
– scratch on corneal surface
– caused by dirt, sand,
insects, or contact with
another athlete’s finger
– symptoms: pain and
watering of the eye
– don’t rub eye, patch eye
Corneal Abrasion
Injuries to the Eye
• Retinal Detachment
– caused by blow to eye or
head
– separation of retina from
underlying tissue
– symptoms: flashes of
light, “curtain” covering
field of vision
– patch eye and send to
physician
Detached Retina
Injuries to the Eye
• Fractures (“blow out”)
– caused by direct blow
– symptoms: swelling,
bleeding & double vision
– control bleeding, patch
with sterile gauze,
physician
– Most orbital fractures
require surgery
Orbital / Blow Out Fracture
Injuries to the Eye

The Spine
• ROM of spine

– side to side (lateral
flexion)
– rotation (cervical &
lumbar only)
Functions of the Spinal Column
1. Protection

Injuries to Spinal Column
• Spondylolysis – defect
in vertebrae caused by
repeated stress from
hyperextension
