Which imaging study is typically best to detect osseous abnormalities and proximity to hardware in a foot wound?

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

Answer: (A)

Plain X-ray is typically the best study because it directly visualizes cortical bone and any radiopaque hardware in a single image, making it easy to detect bone abnormalities such as fractures or bone loss and to assess how close the bone is to fixation devices. It’s fast, widely available, and inexpensive, which is ideal for an initial evaluation of a foot wound. If more detail is needed, CT can offer superior delineation of complex bone anatomy and precise relationships to hardware, but it isn’t as routinely used first-line due to cost, radiation, and potential artifacts from metal. MRI excels at soft tissue and marrow assessment but can be limited by hardware-related artifacts and is not as straightforward for evaluating osseous proximity to implants. Ultrasound is great for soft tissue evaluation and locating superficial foreign bodies, but it doesn’t image bone well.
