Cervical Spine Grating (Crepitus) Evaluation and Management

Initial Assessment and Risk Stratification

The American College of Cardiology is not relevant here, however, checking for high-risk features that would indicate potential cervical spine injury, such as midline cervical tenderness, focal neurological deficit, altered mental status, intoxication, or distracting injury, is crucial in the initial assessment 1
Evaluating functional impact, such as difficulty driving due to limited cervical range of motion, or inability to perform work tasks requiring neck movement, is important for determining the appropriate management approach 2

The American College of Radiology recommends starting with three-view cervical spine radiographs (anteroposterior, lateral, and open-mouth odontoid views) if trauma is suspected, though these detect only about one-third of fractures visible on CT 3
The American College of Radiology also states that CT scan is the gold standard for excluding cervical spine fractures with 88.6% sensitivity, significantly superior to plain radiographs 3
MRI should be reserved for patients with neurological deficits, suspected spinal cord compression, or when ligamentous injury needs evaluation—MRI can identify injuries missed by CT in symptomatic patients 3
Flexion-extension radiographs are not recommended as they rarely demonstrate instability not already identified on conventional radiographs and are often inadequate due to limited cervical excursion 3

Avoiding prolonged immobilization is recommended, as cervical collars should not be used for degenerative conditions, as they limit normal proprioceptive input and can cause muscle atrophy (1-3% strength loss per day) 2
Maintaining activity is crucial, as bed rest causes bone density to decrease 2% per week and muscle strength to decline 10-15% per week, creating a cascade of complications 2
Non-operative treatment remains first-line, however the specific details of this are not cited in the article

Do not over-image, as a single lateral cervical radiograph is insufficient to exclude injury in trauma patients, but extensive imaging is unnecessary for isolated degenerative crepitus 3
Do not prescribe aggressive passive range of motion exercises, as these can cause harm and should be performed cautiously within the patient's comfort zone 2
