Dear Sirs,We read Dr. Harshavardhana et al.’s article The furcal nerve revisited and found it interesting. Nevertheless we have confusions about same points this study.[1]They reported It is formed by ventral and dorsal rami of L1-L4 nerve roots with contribution from 12th thoracic nerve (i.e. subcostal nerve). After the anterior rami of the upper four lumbar nerves have supplied psoas and quadratus lumborum segmentally, they form the pleksus in the substance of psoas major.[2,3]Juliana Farny et al. reported The lumbar plexus originated from the first four lumbar ventral rami that joined within the substance of the psoas major.[4]As a result, the sentence will be eligible to be corrected as stated above Lumbar plexus is formed by ventral rami of L1-L4 nerve roots.[1-4]Imre Nurcan,Kocabiyik Necdet
