Whiplash Injury Evaluation and Treatment

Definition and Mechanism

  • Whiplash describes a sudden biphasic movement of the head and cervical spine that typically occurs during motor vehicle accidents, especially rear-end collisions, affecting multiple soft tissue structures in the neck including muscles, ligaments, facet joints, and discs 1

Clinical Presentation

  • Common symptoms of whiplash include neck pain and stiffness, point tenderness in the cervical spine, upper extremity pain or paresthesia, and muscle spasm in paraspinal and suboccipital regions 1

Evaluation

Clinical Assessment

  • A detailed history focusing on mechanism of injury and symptom progression is necessary for evaluation 1
  • Physical examination should assess cervical range of motion, tenderness on palpation of cervical spine, paraspinal and suboccipital muscles, and neurological examination for radicular symptoms 1
  • Assessment for signs of cervical instability is crucial 2

Imaging

  • Initial imaging should be guided by clinical suspicion for fracture or instability 3, 4
  • Plain radiographs have low sensitivity (36%) for identifying cervical injuries, and a minimum of 3 views is recommended when performed 3
  • CT scan is significantly more sensitive than radiographs (98% sensitivity) and is recommended when fracture is suspected based on clinical criteria 3
  • MRI is most sensitive for detecting soft tissue injuries but has limited value in WAD diagnosis, and tends to overestimate severity of ligament injuries 2, 3, 4

Treatment

Acute Phase

  • Early mobilization and return to normal activities are recommended over immobilization with cervical collars 4, 6
  • Prolonged immobilization with rigid collars can lead to complications such as pressure sores, increased intracranial pressure, and potential airway problems 7

Chronic Phase

  • No cited facts are available for this section

Common Pitfalls and Caveats

  • Overreliance on imaging findings can lead to misdiagnosis, as diagnosis of WAD is primarily clinical 2, 4
  • Excessive immobilization may delay recovery 7
