Gluteus Maximus
O: Ilium, sacrum, coccyx, sacrotuberous ligament
I: gluteal tuberosity, IT tract
In: Inferior gluteal nerve (L5,S1,S2)
A: extends and laterally rotates thigh, supports extended knee
what emerges above the piriformis?
superior gluteal vessels and nerves
2 groups of vessels and nerves emerge inferior to piriformis,
1st group
1. sciatic nerve (L4,5,S1,2,3)
2. Inferior gluteal nerve
3. Inferior gluteal artery and 4. vein (supply piriformis, obturator internus and gl. max)
5. Post. femoral cutaneous nerve
group of 3 structure emerging below the piriformis
1. Nerve to obturator internus (l5,S1,2)
2. Internal pudendal vessels
3. Pudendal nerve (S2,3,4)
emerge from greater sciatic foramen and run through lesser sciatic foramen
Sciatic Nerve
safe side- lateral, for injections
common peroneal (L4,5,S1,2)
Tibial (L4,5,S1,2,3)
The only structure enetering the gluteal region via the lesser sciatic foramen
obturator internus
Gluteus Medius
O: gluteal surface of ilium to
I: greater trochanter
In: superior gluteal
A: abducts and medially rotates thigh
Gluteus Minimus
O: gluteal surface of ilium to
I: anterior aspect of greater trochanter
In: superior gluteal
A: abducts and medially rotates the thigh
O: pelvic surface of sacrum to
I: greater trochanter
In: Sacral (S1-S2)
A: laterally rotates thigh
Obturator Internus
O:ischiopubic rami, obturator membrane to
I: greater trochanter
In: Nerve to obturator
A: Abducts and laterally rotates thight
Superior glamellus
O: Ischial spine to
I: obturator internus tendon
In: nerve to obturator internus
A: laterally rotates thigh
Inferior glamellus
O: Ischial tuberosity to
I: Obturator internus tendon
In: nerve to quadratus femoris
A: laterally rotates thigh
Quadratis femoris

"the carpet" of the sciatic nerve
ischial tuberosity to intertrochanteric crest
IN: nerve to quadratis femoris (L4,5,S1)
A: laterally rotates thigh
Tensor Fascia Latae
anterior superior iliac spine and outer lip of iliac crest to iliotibial tract
I: superior gluteal
A: flexes, abducts and medially rotates the thigh
superior gluteal nerve
-runs along with superior gluteal vessels thru greater sciatic foramen (sup to piriformis)
-between gluteus medius and minimus
-along with deep branch of superior gluteal artery
-Innervates gluteus medius, minimus, and tensor fasciae latae (all abductors of the hip)
small lateral rotator muscles (stabilize the hip)
1. quadratis femoris
2. obturator internus
3. superior glamellus
4.inferior glamellus
5. piriformis
6. obturator externus
Gluteal arteries
-superior and inferior gluteal arteries are branches of the internal iliac artery
-they supply the entire gluteal region, with the largest branches being muscular
