Imaging Guidelines for Suspected Spine Fractures Post-Fall

Initial Imaging Evaluation

The American College of Radiology recommends plain radiographs (X-rays) of both the cervical spine and lumbosacral spine as the initial imaging modality for suspected fracture evaluation at three weeks post-fall, with a rating of "usually appropriate" (9/9) for suspected vertebral body fracture based on acute or subacute symptomatology 1
Plain radiographs should include at minimum 2 views of each region of interest (anteroposterior and lateral projections) to effectively demonstrate vertebral body fractures, compression deformities, and alignment abnormalities at this subacute time point 1

For cervical spine evaluation, the American College of Radiology suggests an X-ray with 2 views minimum (AP and lateral), and if the cervicothoracic junction is not adequately visualized, a swimmer's view may be added, with clinical indication "Neck pain 3 weeks post-fall, evaluate for fracture" 2, 3
For lumbosacral spine evaluation, the clinical indication should be "Low back pain 3 weeks post-fall, evaluate for fracture" 2

If initial radiographs are negative but clinical suspicion remains high, MRI without contrast is the next appropriate study, rated 9/9 for suspected fracture with negative initial radiographs, as it is superior for detecting occult fractures, bone marrow edema, and soft tissue injuries not visible on plain films 1
CT without contrast is an alternative if MRI is contraindicated or unavailable, though it involves higher radiation exposure, with a rating of 7/9 1

The American College of Radiology emphasizes the importance of documenting clinical details such as duration and character of pain, presence of neurological symptoms, and risk factors for fracture (age >50, osteoporosis, chronic steroid use >3 months, prior fragility fractures) to justify imaging 1, 4
High-risk patients (elderly, osteoporotic, on steroids) may require further evaluation with MRI if suspicion persists, as 30-40% bone destruction is needed before fractures become visible on X-ray 4, 5
