Variabilities in the course of the nerve are well documented in the literature. In a previous paper, we defined a tight fascial canal that completely surrounds the LFCN in the proximal thigh. These 2 factors sometimes render finding the nerve intraoperatively, to treat meralgia paresthetica, very challenging.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>OBJECTIVE:<\/jats:bold>\n                    To explore the use of preoperative ultrasound to minimize operative time and eliminate situations in which the nerve is not found.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>METHODS:<\/jats:bold>\n                    Since 2011, we have used preoperative ultrasound-guided wire localization (USWL) in 19 cases to facilitate finding the nerve intraoperatively. Data were collected prospectively with recording of the timing from skin incision to identifying the LFCN; this will be referred to as the skin-to-nerve time.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>RESULTS:<\/jats:bold>\n                    In 2 cases, the localization was incorrect. In the 17 cases in which the LFCN was correctly localized, the skin-to-nerve time ranged from 3 min to 19 min. The mean was 8.5 min, and the median was 8 min.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>CONCLUSION:<\/jats:bold>\n                    Preoperative USWL is a useful technique that minimizes the time needed to find the LFCN. For the less experienced surgeon, it is extremely valuable. For the experienced surgeon, it can identify anatomical abnormalities such as duplicate nerves, which may not be readily recognizable without ultrasound. Collaboration between the surgeon and the radiologist is very important, especially in the early cases.\n                  <\/jats:p>","DOI":"10.1093\/ons\/opw009","type":"journal-article","created":{"date-parts":[[2017,5,18]],"date-time":"2017-05-18T02:10:13Z","timestamp":1495073413000},"page":"402-408","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":24,"title":["Preoperative Ultrasound-Guided Wire Localization of the Lateral Femoral Cutaneous Nerve"],"prefix":"10.1227","volume":"13","author":[{"given":"Amgad S.","family":"Hanna","sequence":"first","affiliation":[{"name":"Department of Neurological Surgery, University of Wisconsin, Madison, Wisco-nsin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark E.","family":"Ehlers","sequence":"additional","affiliation":[{"name":"University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth S.","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Wisconsin, Madison, Wisc-onsin"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2017,6]]},"reference":[{"issue":"3","key":"bib1-20240909","doi-asserted-by":"crossref","first-page":"294","DOI":"10.1007\/s00415-004-0310-x","article-title":"Incidence rates and determinants in meralgia paresthetica in general practice","volume":"251","author":"van Slobbe","year":"2004","journal-title":"J Neurol"},{"issue":"3","key":"bib2-20240909","doi-asserted-by":"crossref","first-page":"600","DOI":"10.1097\/00006534-199709000-00008","article-title":"Anatomical course of the lateral femoral cutaneous nerve and its susceptibility to compression and injury","volume":"100","author":"Aszmann","year":"1997","journal-title":"Plast Reconstr Surg"},{"issue":"3","key":"bib3-20240909","doi-asserted-by":"crossref","first-page":"365","DOI":"10.1002\/ca.20766","article-title":"Anatomical variability of the lateral femoral cutaneous nerve: findings from a surgical series","volume":"22","author":"Carai","year":"2009","journal-title":"Clin Anat"},{"issue":"(4)","key":"bib4-20240909","doi-asserted-by":"crossref","first-page":"341","DOI":"10.3171\/jns.1962.19.4.0341","article-title":"Meralgia paresthetica.
