Muscular branches of posterior femoral cutaneous nerve
Journal Title: The Journal of Community Health Management - Year 2016, Vol 3, Issue 2
Abstract
The posterior femoral cutaneous nerve is one of the branches from the sacral plexus formed by ventral rami of L4 to S4 spinal nerves. The textbooks of Anatomy describe the posterior femoral cutaneous nerve as a sensory nerve, the skin over the lower part of the gluteal region, the perineum, the posterior surface of the thigh and the posterior surface of the leg. The posterior femoral cutaneous nerve derives its fibres from the posterior divisions of the ventral rami of the first and second and anterior divisions of the ventral rami of second and third sacral nerves. Bardeen and Elting & Hortwitz2 have described prefixed and postfixed types of lumbosacral plexus on the basis of spinal nerves taking part in the formation of this plexus. Thane has described the formation of this plexus.3 Thane has described the formation of the posterior femoral cutaneous nerve by two divisions in the gluteal region particularly when the two divisions of the i.e. tibial and common peroneal of the sciatic nerve were separate at their origin.3 Hollinshed has described the variations in the segmental origin of the posterior femoral cutaneous nerve, which may be derive its fibres from the fourth lumbar to the fourth sacral nerve.4 No muscular branch arising from the posterior femoral cutaneous nerve or any of its branches has been reported in the available literature. During the routine dissection of the lower limbs, the muscular branches arising from the posterior femoral cutaneous nerve and supplying the gluteus maximus muscle was noticed. In order to determine whether this occurrence was a rare anomaly or it was a common variation, the present study was undertaken.
