superior gluteal nerve

The superior gluteal nerve originates in the sacral plexus.

The pelvis sags on the opposite side of the lesioned superior gluteal nerve.

There is no cutaneous innervation for sensation that stems from the superior gluteal nerve.

People with a lesion of superior gluteal nerve have weakness of abducting the thigh at the hip.

The superior gluteal nerve arises from the sacral plexus and only has motor innervation associated with it.

Dysfunction of the gluteus medius or the superior gluteal nerve can potentially be indicated by a positive Trendelenburg's sign.

Tensor fascia latae is innervated by the superior gluteal nerve, L4, L5 and S1.

Weakness or paralysis of these muscles caused by a damaged superior gluteal nerve can result in a weak abduction in the affected hip joint.

Paralysis of this muscle or gluteus medius, such as may be caused by the superior gluteal nerve palsy, can lead to difficulty abducting the leg.

Between the gluteus medius and gluteus minimus are the deep branches of the superior gluteal vessels and the superior gluteal nerve.

The superior gluteal nerve is a nerve that originates in the pelvis and supplies the gluteus medius, the gluteus minimus, and the tensor fasciae latae muscles.

At its origins of the anterior rami of L4, L5, and S1 nerves, the superior gluteal nerve exits the pelvis via greater sciatic foramen superior to the pififormis.

If the superior gluteal nerve or obturator nerves are injured, they fail to control the gluteus minimus and medius muscles properly, thus producing an inability to tilt the pelvis upward while swinging the leg forward to walk.

This determines the name of the vessels and nerves in this region - the nerve and vessels that emerge superior to the piriformis are the superior gluteal nerve and superior gluteal vessels.

The superior gluteal nerve passes backward through the greater sciatic foramen, above the piriformis: the inferior gluteal nerve also passes backward through the greater sciatic foramen but below the piriformis."

When a person with paralysis of the superior gluteal nerve is asked to stand on one leg, the pelvis descends on the unsupported side, indicating that the gluteus medius on the contralateral side is weak or non-functional.

Injury to the superior gluteal nerve results in a characteristic motor loss, resulting in a disabling gluteus medius limp, to compensate for weakened abduction of the thigh by the gluteus medius and minimus, and/or a gluteal gait, a compensatory list of the body to the weakened gluteal side.
