Cervical Whiplash Flashcards
What describes an acute whiplash injury?
Sudden or excessive:
- Hyperextension
- Hyper Flexion
- Rotation of the neck
What scenario may cause a Whiplash injury?
- Road Traffic accident
- Sports injury
- Falls
- Assaults
Most common cause of a Whiplash injury?
Rear-end vehicular collisions at speeds of less than 14mph.
How does a rapid deceleration cause Whiplash?
When the cervical Spine flexes the movement may be sufficient to cause longitudinal distraction and neurological damage. Hyperextension may occur in the subsequent recoil.
How many grades of injury are within a Whiplash injury?
Grade 0-4
What does a Grade 0 Whiplash injury consist of?
No complaints or physical signs.
What does a Grade 1 Whiplash injury consist of?
Indicates neck complaints but no physical signs.
What does a Grade 2 Whiplash injury consist of?
Indicates neck complaints and musculoskeletal signs.
What does a Grade 3 Whiplash injury consist of?
Neck complaints and neurological signs.
What does a Grade 4 Whiplash injury consist of?
Neck complaints and fracture/dislocation.
Where do most Cervical spine fractures occur at?
- C2
- C6-C7
Where do most fatal Cervical spine injuries occur at?
Upper Cervical levels:
- Cranio-Cervical junction C1
- C2
Why do women sustain higher rates of whiplash?
Less developed neck muscles.
What and when would the Canadian Cervical Spine Rule (CCR) be applied?
Decision making tool used to determine when radiography should be utilised during trauma.
Trauma patients who are alert and stable.
High risk factors to be taken into account when assessing a Whiplash injury?
- > 65 years old
- Paraesthesia in extremities
- Dangerous mechanism of injury:
- Fall from height
- Axial load on the head
- High speed Vehicle collision
- bicycle collision
Low risk factors to be taken into account when assessing a Whiplash injury?
- Low speed vehicle collision:
- Able to sit rather than lie down in the emergency room
- Ambulatory at anytime
- Delayed onset of neck pain
- Absence of midline Cervical spine tenderness
Clinical symptoms may not develop until 6-12 hours after the injury, what do these symptoms include?
- Neck Pain (may peak 1-2 days after)
- Jaw Pain
- Paraspinal muscle tightness
- Interscapular and LBP
- Muscle spasm
- Reduced ROM and neck tenderness
- Headaches, Fatigue, Dizziness, Vertigo, Vision
- Numbness in shoulders and arms
- Paraesthesia and weakness in arms and legs
- Insomnia, Anxiety, Depression
- Hyperactive tendon reflexes
Risk factors for serious Whiplash injuries:
- Immediate onset of pain
- > 65 years old
- Dangerous mechanism of injury
- Unable to walk or sit following injury
Do not examine neck movements until you have excluded:
- Feature of serious head or neck injury
- Altered level of consciousness
- A focal neurological deficit or Paraesthesia in the extremities
- Midline Cervical Tenderness
Why would you assess for yellow flags?
Any psychological barriers that may hinder progression and cause the injury to become chronic.
Differential Diagnosis to consider following serious injury as another possible cause of acute neck pain and stiffness.
- Spinal Fracture
- Cervical Disc Herniation
- Subarachnoid Heamorrhage
- Meningitis (systemic infection)
