Why are vertebral fractures often underdiagnosed in osteoporosis?

• A. They cause intense pain prompting immediate imaging
• B. They are rare
• C. They require expensive MRI
• D. They are often asymptomatic or mild and may be missed without targeted imaging like VFA or lateral spine X-rays

Answer: (D)

Many vertebral fractures in osteoporosis are silent or only mildly painful, so they don’t always trigger imaging or clinical concern. Because elderly patients may attribute back changes to aging or wear and tear, a fracture can go unnoticed unless doctors specifically look at the spine. Targeted imaging, like vertebral fracture assessment on a DXA scan or lateral spine X‑rays, is needed to reveal the compression deformities and endplate changes that signify a fracture. Without that focused look at the thoracic and lumbar vertebrae, these fractures can be missed, even though osteoporosis has already put the spine at risk. The other ideas don’t fit as well because intense pain isn’t universal with these injuries, vertebral fractures are common—not rare—in osteoporosis, and MRI isn’t required for routine detection—X‑ray or VFA is usually sufficient to identify most fractures.
