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

Abstract

Identification and retrieval of soft-tissue foreign bodies (STFB) poses significant challenges in the emergency department. Prior studies have demonstrated the utility of ultrasound (US) in identification and retrieval of STFBs, including radiolucent objects such as wood. We present a case of STFB extraction that uses US 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.

Ultrasound Guided Posterior Tibial Nerve Block to Facilitate Foreign Body Removal in a School-Aged Child

“…The technique of using POCUS to identify the longitudinal axis of the foreign body so that traction can be applied in parallel with this axis, thus limiting adjacent soft tissue destruction, has been previously described. 4 The foreign body’s length of 3 cm corresponded to our pre-procedure POCUS estimate. POCUS was repeated post-procedure to ensure that the object had been removed in its entirety.…”

Usage of Ultrasonography for the Diagnosis of a Foreign Body of the Tongue

“…Таким образом, традиционно применяемая при подозрении на наличие инородных тел рентгенография не позволяет визуализировать ИТ с низкой рентгеновской плотностью (деревянные щепки, фрагменты пластика, стекла и т.д. ), а также определить их синтопию, что делает ее малоэффективным методом для выявления и успешного извлечения инородного предмета [6].…”

“…В противоположность этому, ультразвуковое исследование (УЗИ) позволяет обнаружить как рентгенопозитивные, так и рентгенонегативные инородные тела, уточнить их топографию относительно окружающих тканей, определить выраженность перифокального воспаления, выявить признаки абсцедирования [2,6,13].…”

Ultrasound-guided surgery in musculoskeletal medicine

“…1. The role of US to accurately localize and remove soft tissue foreign bodies, hematoma, calcific deposits, and ossicles were demonstrated in several papers [7][8][9][10]. They are often referred to as the "first generation" US-guided surgery [6].…”
