APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The posterior femoral cutaneous nerve of the thigh gives off three cutaneous branches. The branches are dispersed to the region of the buttock, the perineum and to the posterior thigh and leg.

Detailed explanation-2: -The posterior femoral cutaneous nerve, also known as the posterior cutaneous nerve of the thigh, is a sensory branch of the sacral plexus. It arises from anterior and posterior divisions of anterior rami of S1, S2 and S3 nerves.

Detailed explanation-3: -The most common symptom of this nerve injury is the inability to sit without pain or discomfort. Most of the time, people with this injury can walk and run pain free. Symptoms can range from a dull, achy pain to numbness and tingling in the tailbone and upper hamstring areas.

Detailed explanation-4: -The posterior femoral cutaneous nerve gives rise to branches that innervate the gluteal region, perineum, posterior thigh and proximal posterior leg: The three or four gluteal branches (inferior clunial nerves) innervate the skin of the gluteal fold region.
