Treatment of Cervical Strain Following Trauma

Initial Assessment and Red Flag Screening

No "red flags" are present in this case, including no constitutional symptoms, no neurological deficits, no severe intractable pain, and no risk factors for infection or malignancy, as recommended by the American College of Radiology 1, 2
Delayed headache onset is consistent with whiplash-associated disorder (WAD) rather than serious intracranial pathology, particularly given the absence of loss of consciousness, photophobia, or nausea/vomiting, according to the Journal of the American College of Radiology 3
Imaging is not indicated for this presentation, as the American College of Radiology guidelines state that imaging has limited value in WAD when clinical factors suggest mechanical injury without red flags 1, 3

International consensus guidelines recommend against cervical collar use by first aid providers due to growing evidence of complications and lack of benefit in patients without high-risk spinal injury criteria, as stated in Circulation 4
This patient has no indication for spinal immobilization, as confirmed by guidelines in Circulation 4 and Anaesthesia 5

Most acute cervical strain improves within 7-8 weeks with conservative management, though approximately 50% may have some persistent symptoms at one year, according to the Journal of the American College of Radiology 1
MRI findings in post-traumatic neck pain often overestimate injury severity and should not drive management in the absence of neurological symptoms, as reported by the Journal of the American College of Radiology 3
Soft tissue injuries visible on MRI are common after cervical trauma but do not necessarily correlate with clinical outcomes or require surgical intervention, as noted by the Journal of the American College of Radiology 3
