Extremity Trauma: Foreign Bodies and Vascular Injury
It is important for physicians to be mindful of the possibility of a foreign body in the context of extremity trauma. Patients with foreign bodies may not suspect their presence, and a significant proportion of foreign bodies are missed by the initial treating physician. Trauma injuries to the peripheral vasculature can be divided into blunt and penetrating trauma, and can also be classified as occlusive or nonocclusive injuries. This review details the assessment and stabilization, diagnosis, treatment and disposition, and outcomes for patients with foreign body and vascular injuries. Figures show beside ultrasonography using a linear ray probe that demonstrates a foreign body wood splinter in soft tissue, the major arteries of the upper and lower extremities, and measurement of the ankle-brachial index in an injured limb with suspected vascular injury. Tables list supplies needed to perform bedside ultrasound-guided foreign body removal, steps to remove a foreign body under ultrasound guidance, hard and soft signs of arterial injuries, and high-risk orthopedic injuries and their commonly associated vascular injury. This review contains 4 figures, 4 tables, and 51 references.
