Abstract
The sciatic nerve is the largest nerve in the human body. It originates from L4-L5 and S1-S3 spinal segments of the spinal cord and travels posteriorly through the lower limb providing significant portion of innervation to this anatomical region. The surgical procedures at the infragluteal region and transgluteal approaches to the sciatic nerve involves different incisions, level of dissection and are based on good knowledge of regional anatomy. During anatomical dissection of a 75 years-old cadaver, the course of the branches of the sacral plexus, the features of their origin and innervation zones were studied. To our knowledge there is only one report of a similar variation when the sciatic nerve bifurcates and then merges until its division into the tibial and fibular nerves.
