Imaging Guidelines for Stable Compression Fractures

Initial Imaging Approach

The American College of Radiology recommends radiography as the appropriate first-line imaging for suspected vertebral compression fractures, particularly in patients with osteoporosis or steroid use 1
Plain radiographs with anteroposterior and lateral views are useful for assessing compression fractures in patients with low suspicion of trauma or minor trauma, providing valuable information for diagnosis and treatment planning 1
Upright radiographs provide functional information about axial loading, and flexion-extension views can evaluate spine stability, helping to determine the need for further imaging or intervention 1

The American College of Radiology suggests that CT should be obtained when there are concerns about posterior column involvement or instability, as it provides detailed analysis of fractures extending to the posterior column, pedicle integrity, and posterior cortex 1
CT is indicated for detecting displaced or retropulsed fractures that may compromise the spinal canal, particularly in cases of trauma mechanism suggesting instability 2, 3
The American College of Radiology recommends CT for evaluating the extent of canal compromise and posterior element disruption in patients with neurological deficits, although MRI is often preferred for its superior soft tissue visualization 1

The American College of Radiology prefers MRI without contrast as the advanced imaging modality for compression fractures when additional evaluation beyond radiographs is needed, due to its superiority in determining fracture acuity, distinguishing benign from pathologic fractures, and assessing spinal canal compromise 1, 4
MRI provides diagnostic and prognostic information without radiation exposure, making it a valuable tool for patient management and treatment planning 5

For suspected stable compression fracture, the American College of Radiology recommends starting with radiographs (AP and lateral, consider flexion-extension if stability questioned), and proceeding with conservative management if radiographs confirm simple compression fracture without red flags 1, 4, 6
CT should be reserved for cases where posterior column integrity must be assessed, retropulsion or canal compromise is suspected, MRI is contraindicated or equivocal, or surgical planning requires detailed bony anatomy 1, 3, 5
