Material and methods We analyzed 131 lumbar plexuses from 68 embalmed cadavers at the Cadaveric Surgical Training Center, Faculty of Medicine, Chiang Mai University in the period between April 2012 and June 2013. Morphometric measurements were taken. Results The lumbar plexus was located within psoas major muscle (100.0%). The iliohypogastric nerve originated from the ventral rami of L1(96.5%) followed by the ilioinguinal nerve (90.1%). The genitofemoral nerves originated from the ventral rami of L1and L2(98.5%). The lateral femoral cutaneous nerves (LFCN) originated from the ventral rami of L2and L3(84.0%). The femoral and obturator nerves originated from ventral rami of L2–L3–L4(100.0%). The distance between the origin of LFCN to L3transverse process was at an average 1.96 ± 0.67 cm. The distance from nerve to L4transverse process was above L3and between L3and L4transverse process at an average 2.8 ± 1.63 cm. The distance between femoral nerve to L3and L4transverse process was inferior to L4transverse process at an average of 5.13 ± 2.18 cm and 2.53 ± 2.26 cm, respectively. The distance between obturator nerve to L3and L4transverse process was found inferior to L4transverse process at an average 5.42 ± 1.73 cm and 2.75 ± 1.75 cm, respectively. Discussion The knowledge of anatomical variations of LP may be important for administration of local anaesthetic agents and avoid any inadvertent injuries. 2018-09-05T03:09:27Z 2018-09-05T03:09:27Z 2016-06-01 Journal 00032778 2-s2.0-84969988679 10.1016/j.jasi.2016.04.003 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84969988679&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/56136
