What imaging study should be used to look for foreign bodies or bone destruction in an infected puncture wound?

• A. MRI
• B. CT scan
• C. Ultrasound
• D. X-ray

Answer: (D)

Plain X-ray is the best starting imaging when you’re evaluating an infected puncture wound for a possible foreign body or bone involvement. It quickly reveals many common foreign bodies (like metal or glass) and can show bone changes from infection, such as periosteal reaction or defects in the cortex. It’s fast, inexpensive, and widely available, making it ideal in the emergency setting. If a foreign body is suspected but not seen on X-ray, or if the object is radiolucent (like wood) or if deeper bone detail is needed, other imaging such as ultrasound or CT can be used, and MRI may be considered in specific scenarios but is not first-line in acute infection.
