We have carried out dissection in 20 Nepalese cadavers. Out of 40 dissected gluteal regions, 37 exhibited typical appearance of sciatic nerve, piriformis muscle, and their relations resembling type-a, whereas 3 gluteal regions showed composite structural variations resembling type-b and type-c based on Beaton and Anson\u2019s classification. Knowledge pertaining to such variations will be helpful during a surgical intervention in the gluteal region and in turn reduces the risk of injuring these nerves which are more susceptible to damage. Our study reports such variations in Nepalese population which will be helpful during evaluation of the pain induction in various test positions and also useful for analysis of the range of the neurological deficiency in sciatic nerve neuropathies. The present study also explains the basis of the unsuccessful attempt of the sciatic nerve block during popliteal block anaesthesia.<\/jats:p>","DOI":"10.1155\/2020\/7165818","type":"journal-article","created":{"date-parts":[[2020,3,31]],"date-time":"2020-03-31T23:51:01Z","timestamp":1585698661000},"page":"1-6","source":"Crossref","is-referenced-by-count":8,"title":["Composite Anatomical Variations between the Sciatic Nerve and the Piriformis Muscle: A Nepalese Cadaveric Study"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3322-8899","authenticated-orcid":true,"given":"Ameet Kumar","family":"Jha","sequence":"first","affiliation":[{"name":"University of Central Nicaragua, Managua, Nicaragua"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prakash","family":"Baral","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Gandaki Medical College, Pokhara, Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","year":"2018"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1186\/s13104-015-1626-6"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.14260\/jemds\/2014\/2362"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(00)84887-4"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.4103\/jcis.jcis_58_17"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-013-1180-7"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1002\/jor.23186"},{"key":"9","first-page":"721","volume":"51","year":"2010","journal-title":"Singapore Medical Journal"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1002\/ar.1090700102"},{"key":"11","first-page":"686","volume":"20","year":"1938","journal-title":"J Bone Joint Surg Am"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1017\/S0317167100015298"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.7860\/JCDR\/2014\/9116.4725"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocn.2008.01.017"},{"issue":"12","key":"16","first-page":"953","volume":"5","year":"2014","journal-title":"International Journal of Pharmaceutical Sciences and Research"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.12659\/MSM.894353"},{"issue":"19","key":"18","first-page":"139","volume":"19","year":"2009","journal-title":"Turkish Neurosurgery"},{"issue":"2","key":"19","first-page":"27","volume":"1","year":"2011","journal-title":"National Journal of Medical Research"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1590\/s1806-00132011000400009"},{"issue":"3","key":"21","first-page":"175","volume":"70","year":"2016","journal-title":"Folia Morphol"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-005-0056-x"},{"issue":"4","key":"23","first-page":"261","volume":"18","year":"2014","journal-title":"European Journal of Anatomy"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.5603\/fm.a2015.0130"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1016\/j.tria.2016.11.001"},{"issue":"1","key":"26","first-page":"26","volume":"2","year":"2011","journal-title":"Neuroscience Research Letters"},{"issue":"1","key":"27","first-page":"62","volume":"2","year":"2013","journal-title":"Journal of Krishna Institute of Medical Sciences University"},{"issue":"8","key":"28","first-page":"1502","volume":"5","year":"2011","journal-title":"Journal of Clinical and Diagnostic Research"},{"key":"29","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-013-1179-0"},{"key":"30","doi-asserted-by":"publisher","DOI":"10.1002\/ca.20893"},{"key":"31","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-012-0940-0"}],"container-title":["Case Reports in Neurological Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crinm\/2020\/7165818.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crinm\/2020\/7165818.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crinm\/2020\/7165818.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,31]],"date-time":"2020-03-31T23:51:12Z","timestamp":1585698672000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/crinm\/2020\/7165818\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3,31]]},"references-count":29,"alternative-id":["7165818","7165818"],"URL":"https:\/\/doi.org\/10.1155\/2020\/7165818","relation":{},"ISSN":["2090-6668","2090-6676"],"issn-type":[{"value":"2090-6668","type":"print"},{"value":"2090-6676","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,3,31]]}}}
