Peer Review Status: Internally Peer Reviewed

This nerve, when present (64% of cases), arise from the second and third sacral nerves. Instead of piercing the sacrosciatic ligament, the nerve may accompany the pudendal nerve or pass between the ligament and gluteus maximus. It may be replaced by a branch of the posterior femoral cutaneous nerve or by the perforans coccygeus major, which arises from the third and fourth or the fourth and fifth sacral nerves. It is sometimes joined at its origin with the pudendal nerve.
