The superior gluteal nerve
is a nerve
that originates in the pelvis
which supplies the gluteus medius
, the gluteus minimus
, and the tensor fasciae latae
The superior gluteal nerve originates in the sacral plexus
. It arises from the dorsal divisions of the fourth and fifth lumbar and first sacral nerves
: it leaves the pelvis through the greater sciatic foramen
above the piriformis
, accompanied by the superior gluteal artery
and the superior gluteal vein
. It then divides into a superior and an inferior branch.
The superior gluteal nerve and vessels travel above the piriformis muscle through the greater sciatic foramen; the inferior gluteal nerve and vessels travel below the muscle.
Damage to the superior gluteal nerve can lead to the gait disturbance
known as Trendelenburg gait
