Role of Ultrasound in the Identification of Longitudinal Axis in Soft-Tissue Foreign Body Extraction


Identification and retrieval of soft tissue foreign bodies (STFBs) poses significant challenges in the emergency department. Prior studies have demonstrated the utility of ultrasound in identification and retrieval of STFBs, including radiolucent objects such as wood. We present a case of STFB extraction that utilizes ultrasound to identify the longitudinal axis of the object.  With the longitudinal axis identified, the foreign body can be excised by making an incision where the foreign body is closest to the skin. The importance of this technique as it pertains to minimizing surrounding tissue destruction and discomfort for patients has not been previously reported.
