EMORY DPT ANATOMY: MUSCLE OF THE
GLUTEUL REGION
Gluteus maximus - ANS-O: ilium post to post gluteal line; dorsal surface sacrum/coccyx,
sacrotuberous ligament
I: some on gluteal tuberosity, most (3/4) end in iliotibial tract which inserts on lateral condyle of
tibia
A: extends thigh (esp. from flexed position) and assists with lateral rotation; steadies thigh,
assists in rising from sitting position
N: inferior gluteal nerve L5, S1/2
Gluteus medius: - ANS-O: external surface of ilium b/w anterior and posterior gluteal lines
I: lateral surface GT of femur
A: abduct and medial rotate thigh; keep pelvis level when ipsilateral limb is weight-bearing
N: superior gluteal nerve L5, S1
Gluteus minimus: - ANS-O: external surface of ilium b/w anterior and inferior gluteal lines
I: anterior surface of GT
A: abduct and medially rotate thigh; keep pelvis level when ipsilateral limb is weight-bearing
N: superior gluteal nerve L5, S1
Tensor fascia latae: - ANS-O: ASIS and anterior part of iliac crest
I: iliotibial tract which attaches to lateral condyle of tibia
A: abduct and medially rotate thigh; keep pelvis level when ipsilateral limb is weight-bearing
- counteracts the gluteus maximus muscle to maintain proper alignment of the iliotibial tract
(remember, glut max attaches to iliotibial tract too)
-can also help iliopsoas and rectus femoris with hip flexion; lies too far anterior to be a strong
abductor; think of it as more of a synergist for hip movts of flex and abd/IR
N: superior gluteal nerve L5, S1
-is considered a muscle of gluteal region even though it has a more anterior placement**
-enclosed between 2 layers of fascia (so it is NOT fascia itself)
Deep Short Rotators - ANS-Piriformis
Obturator Internus
Superior and inferior gemelli
Quadratus femoris
Piriformis: - ANS-O: anterior surface of sacrum, sacrotuberous ligament
I: superior border of GT of femur
A: laterally rotate extended thigh and abduct flexed thigh
