Open sciatic neurolysis has been noted by the senior author to often only bring temporary relief of the symptoms, with the recurrence presumably due to postoperative scar tissue. Minimally invasive techniques used to decompress the nerve have met with mixed results. This article describes a step\u2010by\u2010step surgical technique designed to maximize patient safety, as well as surgeon orientation, and achieve a thorough neurolysis. Preoperative findings suggestive of piriformis syndrome are described and include retro\u2010trochanteric pain, sciatica\u2010like leg pain, and paresthesias, as well as a positive response to computed tomography\u2013guided injection of dilute ropivacaine hydrochloride and 40 mg of triamcinolone. The operation is performed with the patient in the lateral decubitus position through 2 portals 6 to 8 cm apart, allowing for good triangulation. Dissection is undertaken with a combination of radiofrequency and a laparoscopic peanut, with the assistance of a vascular sling to control the sciatic nerve. Encouraging results have been achieved, and with increasing interest in this procedure, a step\u2010by\u2010step technical description with an accompanying video may prove useful for other experienced hip arthroscopists. Pearls and pitfalls are discussed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Technique Video<\/jats:title>\n                    <jats:p>\n                      <jats:boxed-text content-type=\"video\" position=\"anchor\">\n                        <jats:graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" position=\"anchor\" xlink:href=\"urn:x-wiley:22126287:media:atn2bf01265:atn2bf01265-vimg-mmc1\">\n                          <jats:alt-text>video<\/jats:alt-text>\n                        <\/jats:graphic>\n                      <\/jats:boxed-text>\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>See video under supplementary data.<\/jats:bold>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.eats.2015.03.010","type":"journal-article","created":{"date-parts":[[2015,8,10]],"date-time":"2015-08-10T08:19:00Z","timestamp":1439194740000},"update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":13,"title":["Endoscopic Sciatic Neurolysis"],"prefix":"10.1002","volume":"4","author":[{"given":"Joshua S.","family":"Knudsen","sequence":"first","affiliation":[{"name":"Millennium Institute of Sport and Health Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark O.","family":"McConkey","sequence":"additional","affiliation":[{"name":"Pacific Orthopedics and Sports Medicine North Vancouver British Columbia Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew J.","family":"Brick","sequence":"additional","affiliation":[{"name":"Millennium Institute of Sport and Health Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,8,10]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.otsm.2004.09.008"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1053\/apmr.2002.30622"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nec.2008.07.028"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1053\/jars.2003.50158"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.otsm.2012.09.005"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546508322905"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20210"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ncl.2010.03.017"}],"container-title":["Arthroscopy Techniques"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S2212628715000407?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S2212628715000407?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.eats.2015.03.010","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/full-xml\/10.1016\/j.eats.2015.03.010","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.eats.2015.03.010","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T11:19:15Z","timestamp":1775560755000},"score":1,"resource":{"primary":{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/10.1016\/j.eats.2015.03.010"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,8]]},"references-count":8,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2015,8]]}},"alternative-id":["10.1016\/j.eats.2015.03.010"],"URL":"https:\/\/doi.org\/10.1016\/j.eats.2015.03.010","archive":["Portico"],"relation":{},"ISSN":["2212-6287","2212-6287"],"issn-type":[{"value":"2212-6287","type":"print"},{"value":"2212-6287","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,8]]},"assertion":[{"value":"Elsevier","name":"publisher","label":"This article is maintained by"},{"value":"Endoscopic Sciatic Neurolysis","name":"articletitle","label":"Article Title"},{"value":"Arthroscopy Techniques","name":"journaltitle","label":"Journal Title"},{"value":"https:\/\/doi.org\/10.1016\/j.eats.2015.03.010","name":"articlelink","label":"CrossRef DOI link to publisher maintained version"},{"value":"article","name":"content_type","label":"Content Type"},{"value":"Crown copyright \u00a9 2015 Published by Elsevier Inc.","name":"copyright","label":"Copyright"}]}}
