Ultrasound (US) localization in peripheral nerve surgery has recently become popular. We present a case report illustrating the use of needle-wire localization systems to identify proximal and several distal branches of an injured femoral nerve with a large segmental defect in order to illustrate how such techniques can be used to make surgical repair more efficient, particularly with identifying the distal stump(s).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CLINICAL PRESENTATION<\/jats:title>\n                    <jats:p>We illustrate a case of a 16-yr-old female involved in a traumatic accident that lead to a severe injury of the femoral nerve and artery. The patient presented with a 7.3-cm defect between the proximal and distal aspect of the femoral nerve and its branches, respectively. High-resolution US was used to identify the proximal, large femoral nerve, and 3 distal stumps. By enlisting our musculoskeletal radiology team, we were able to trace distal branches of the femoral nerve and see their target muscles. Three separate US flexible needles were used to locate small muscular branches of the femoral nerve and 1 to locate the proximal stump. Intraoperatively, the localization wires allowed for safe and efficient dissection of proximal and distal nerve stumps in a significantly scarred and edematous plane.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>US-guided needle-wire localization has shown promise in identifying the distal stumps and minimizing tissue dissection.
