The superior gluteal nerve arises from the posterior division of the ventral rami at L4 to S1. The nerve is accompanied by the superior gluteal vessels, descends in an anterior direction after traveling between the gluteus medius and gluteus maximus muscles, and enters the muscle in the posterior surface. 1.The superior gluteal artery is a concluding branch of the posterior trunk of the internal iliac artery. Let's begin with muscle strength testing. They are one of three different types of cluneal nerves (middle and inferior cluneal nerves being the other two). The artery (diameter = 4 mm) as well as the superior gluteal nerve go into the gluteal region via the greater sciatic foramen. This syndrome usually presents with symptoms of pain and dysesthesias in the buttock area, hip or posterior thigh, and/or as radicular pain. Damage to the superior gluteal nerve after the Hardinge approach to the hip. The gluteus maximus muscle is the supplied by the inferior gluteal nerve (root L5, S1 and S2).

The superior cluneal nerves are pure sensory nerves that innervate the skin of the upper part of the buttocks. Superior Gluteal Nerve.

The superior gluteal nerve (SGN) is composed of the L4-S1 nerve roots from the sacral plexus. See Appendix 2-6 and see color plates. These spinal segments are also the most common levels for lumbar disc herniations. Nerve roots leave the spinal cord via the intervertebral foramina (holes or spaces between the vertebrae) and join together from various levels of the spine to travel as cord-like structures, called nerves, to their destinations. Supplies serratus anterior. It arises from the posterior divisions of L4, L5 and S1. What does it supply? Both roots then combine to form a common trunk that consists of both sensory and motor fibers. The gluteus maximus muscle is a vascularized by the muscular branches of the inferior gluteal & superior gluteal arteries, the branches of the internal iliac artery. The posterior third . mechanism. The superior gluteal nerve is responsible for innervation of the gluteus medius, gluteus minimus, and tensor fasciae latae muscles.

Tensor fasciae latae is innervated by the superior gluteal nerve, L5 and S1. Direct damage. Finally, the most common adverse event is neural injury, including the l5 nerve root, the s1 nerve roots as well as the superior gluteal nerve. There are two gluteal nerves: the superior derives from the L4, L5, and S1 spinal roots and the inferior derives from the L5, S1, and S2 roots. And when it comes to actions, it steadies, extends, and laterally rotates the thigh, it helps with getting up from a sitting position, and, when the distal attachment of the gluteus maximus is fixed .
