-
Gluteus maximus
- - Superficial fibres: iliac crest, posterior superior iliac spine, lumbar faschia, sacrum, coccyx
- - Deep fibres: ala of ilium posterior to posterior gluteal line, faschia of gluteus medius, sacrotuberous ligament
- --> Iliotibial tract and gluteal tuberosity on femur
- - Inferior gluteal nerve
- - Extends and laterally rotates hip
-
Gluteus medius
- - Gluteal surface of ala of ilium between anterior and posterior gluteal lines
- --> greater trochanter
- - Superior gluteal nerve
- - Abducts hip
- Anterior fibres medially rotate and flex
- Posterior fibres laterally rotate and extend
-
Gluteus minimus
- - Outer part of ala of ilium between anterior and inferior gluteal lines
- --> Anterior part of greater trochanter
- - Superior gluteal nerve
- - Abducts and medially rotates
-
Tensor fasciae latae
- - Ilium between anterior superior iliac crest and tubercle of crest
- --> iliotibial tract
- - Superior gluteal neve
- - Provides stability to knee and hip in standing
-
Piriformis
- Anterior aspect of middle 3 pieces of sacrum
- through greater sciatic foramen
- --> posterior extremity of upper margin of greater trochanter
- - 2nd and 3rd sacral nerves
- - Laterally rotates
-
Obturator internus
- - Obturator membrane and surrounding bone
- Tendon exits pelvis through lesser sciatic foramen, turns right angle around lesser sciatic notch (bursa)
- --> Greater trochanter above trochanteric fossa
- - Nerve to obturator internus
- - Laterally rotates
-
Superior and Inferior Gemelli
- - Upper and lower margins of lesser sciatic notch
- --> inserts into obturator internus tendon
- - Sup: nerve to obturator internus
- - Inf: nerve to quadratus femoris
- - Laterally rotate
-
Quadratus femoris
- - Outer border of ischial tuberosity
- --> quadrate tubercle on upper aspect of intertrochanteric crest of femur
- - Nerve to quadratus femoirs
- - Laterally rotates
