Medical professionals have begun to utilize single injection combined regional anesthesia methods due to increased patient comfort. In this study, we examined the topographical anatomy of the mid\u2010thigh, which is recommended as the appropriate intervention level for combined AC and SN blockades, in order to provide a safe approach for clinicians. We examined 184 thigh magnetic resonance images (MRI) from 98 patients. We measured the diameter of the mid\u2010thigh, anterior thigh muscle thickness, subcutaneous adipose tissue thickness, and SN depth on the MRIs. We obtained ultrasound (US) images of the vastoadductor membranes (VAM) of 26 volunteers, and measured the vertical distances between the greater trochanter and the adductor tubercle (A) and the greater trochanter and the upper edge of the VAM (B). We then proportioned B to A in order to determine in which part of the thigh the AC was located. The AC was in the distal third of the thigh, and the SN's depth was located in the third quarter of the thigh's diameter. Only the adductor magnus, and no neurovascular structure, was at risk of injury between the AC and the SN. The upper edge of the VAM was 6.5\u2009cm below the mid\u2010thigh, therefore it is not appropriate to suggest performing an AC blockade at mid\u2010thigh. We think that it is safe to perform a combined AC and SN blockade in a single injection in selected patients.<\/jats:p>","DOI":"10.1002\/ca.23927","type":"journal-article","created":{"date-parts":[[2022,7,5]],"date-time":"2022-07-05T07:28:20Z","timestamp":1657006100000},"page":"350-359","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Reevaluation of the topographical anatomy of the mid\u2010thigh: A magnetic resonance and ultrasound imaging study"],"prefix":"10.1002","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0155-7447","authenticated-orcid":false,"given":"Bilge Ipek","family":"Torun","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Department of Anatomy Ankara Yildirim Beyazit University  Ankara Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehtap","family":"Balaban","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Department of Radiology Ankara Yildirim Beyazit University  Ankara Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sukru Cem","family":"Hatipoglu","sequence":"additional","affiliation":[{"name":"Department of Radiology Ankara City Hospital  Ankara Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,7,13]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/AAP.0b013e31827900a9"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-007-0279-0"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-196303000-00011"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/aap.0000000000000261"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/aap.0000000000000052"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.3945\/ajcn.113.065961"},{"key":"e_1_2_7_8_1","volume-title":"Gray's anatomy 42nd edition: the anatomical basis of clinical practice","author":"Gray H.","year":"2020"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.1985.tb02245.x"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12630-013-9992-9"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/aap.0000000000000069"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/ALN.0b013e318279fa0b"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.2011.02621.x"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-018-2094-1"},{"key":"e_1_2_7_15_1","volume-title":"Regional anesthesia: Its technique and clinical applications","author":"Labat G.","year":"1922"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.2010.02333.x"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/aap.0b013e3181bfbf84"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.3344\/kjp.2022.35.2.191"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1213\/00000539-197507000-00020"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1097\/AAP.0b013e318220f172"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.csm.2021.11.006"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ijo.0803026"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.4103\/aer.AER_35_19"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12630-010-9317-1"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-007-0230-4"},{"key":"e_1_2_7_26_1","volume-title":"Comprehensive atlas of ultrasound\u2010guided pain management injection techniques","author":"Waldman S.
