Ultrasound-guided needle localization to aid foreign body removal in pediatric patients.

Patients with podiatric foreign body injury commonly present to the emergency department. Often, the foreign object cannot be easily located or removed, and radiographs are frequently obtained to aid in localization. In cases requiring tissue dissection to remove the foreign bodies, accurate localization is required for safe removal of small and difficult to visualize bodies. We present 2 pediatric cases in which an ultrasound-guided needle localization technique was used to facilitate successful removal of small, difficult to visualize foreign bodies from the plantar foot. Ultrasound-guided needle localization reduced the required incision length and depth and helped to minimize the risk of damage to surrounding tissue.
