Which test is least likely to be used to evaluate an acute leg fracture?

• A. CT
• B. X-ray
• C. Bone densitometry
• D. Bone scan

Answer: (C)

Imaging for an acute leg fracture focuses on quickly revealing the fracture and guiding urgent management. X-rays are the standard first step because they quickly show most acute fractures and are widely available. If a more detailed view is needed to define complex fracture patterns or plan surgery, CT provides cross-sectional, high-detail images. Bone scans can be useful when a fracture is suspected but not visible on X-ray (occult fractures), though they’re not the immediate choice for initial assessment. Bone densitometry, however, measures bone mineral density to assess osteoporosis risk, not to visualize an acute fracture. It doesn’t show fracture lines or help with urgent decision-making, so it’s the least likely test to be used in evaluating an acute leg fracture.
