Which radiographic finding supports a vertebral compression fracture?

Which radiographic finding supports a vertebral compression fracture?

• A. Greater than 20% loss of vertebral body height on imaging
• B. Disc space narrowing with facet joint sclerosis
• C. Widening of the intervertebral foramina
• D. Spinous process fracture only

Answer: (A)

A loss of vertebral body height on imaging points to a vertebral compression fracture. When a vertebra collapses from a compressive force, the height of the affected body decreases, most notably with anterior wedging in osteoporotic fractures. On a lateral spine radiograph, you compare the height of the involved vertebra to the adjacent levels; a reduction of roughly 20% or more in height is a commonly used threshold indicating a compression fracture. This finding helps distinguish compression injuries from other spine issues. Other choices reflect different problems: disc space narrowing with facet joint sclerosis suggests degenerative changes; widening of the intervertebral foramina implies foraminal stenosis or nerve root compression; a spinous process fracture alone is a different fracture pattern. So the hallmark radiographic sign that supports a vertebral compression fracture is substantial loss of vertebral body height on imaging.
