I- medial portion of línea aspera
A- adduction
Adductor longus
O- Pubis
I- medial portion línea áspera
A- adduction
Adductor Magnus
O- pubis and ischium
I- línea áspera and tendon to the medial epicondyle
A- adduction
Gluteus Maximus
O- sacrum and posterior surface of ilium
I- iliotibial band and greater trochanter
A- hip extension and weak abduction in extension
Iliacus
O- iliac fossa
I- lesser trochanter via psoas major tendon
A- hip flexion
Gluteus minimus
O- iliac crest
I- greater trochanter
A- abduction
Internal rotation
Pelvic stabilizer
Gluteus medius
O- posterior iliac crest
I- greater trochanter
A- abduction
Internal rotation
Pelvic stabiliser
Periformis
O- anterior sacrum and sacroiliac joint
I- greater trochanter
A- hip stabiliser, lateral rotator, rotates the femur during hip extension and abducts the femur during flexion of the hip
Quadratus femoris
O- lateral aspect of the ischial tuberosity
I- intertrochanteric crest
A- external rotation hip stabiliser and assists in abduction and adduction in certain positions
Gemellus superior
O- ischial spine
I- medial surface of the greater trochanter
A- hip external rotation, hip abduction with a flexed hip, stabilises head of femur
Gemellus inferior
O- ischial tuberosity
I- medial surface of the greater trochanter
A- hip external rotation, thigh abduction in hip flexed, stabilises head of femur
Obturator internus
O- posterior surface of the obturator membrane and the bony boundaries of the obturator foramen
I- medial surface of the greater trochanter
A- external rotation in hip extension
Abduction in hip flexión and stabilise femur head
Obturator externus
O- external surface of the obturator membrane
I- trochanteric fossa of the femur
A- external rotation in hip extension
Abduction in hip flexión and stabilise femur head
