MuscleActionOriginInsertionInnervationBlood supply
Gluteus medius- Hip abduction
- Hip medial rotation (anterior fibres)
- Hip lateral rotation (posterior fibres)
- Dorsal ilium inferior to iliac crest- Lateral and superior surfaces of greater trochanter- Superior gluteal nerve: L4,L5,S1- Superior gluteal artery
Gluteus minimus- Abducts hip
- Medially rotates hip
- Dorsal ilium between inferior and anterior gluteal lines
- Edge of greater sciatic notch
- Anterior surface of greater trochanter- Superior gluteal nerve: L4, L5, S1- Superior gluteal artery
Gluteus maximus- Hip extension
- Hip lateral rotation
- Hip abduction (middle and upper fibres)
- Posterior surface of ilium
- Posterior superior illiac crest
- Posterior surface of sacrum and coccyx
- Primarily to fascia lata at illiotibial tract
- Upper posterior surface of femur
- Inferior gluteal nerve: L5, S1, S2- Inferior and superior gluteal arteries
- First perforating branch of profunda femoral artery
Tensor fasciae latae- Hip abduction
- Hip medial rotation
- Hip flexion (assists)
- Stabilises hip and knee by placing tension in illiotibial band
- Anterior superior illiac spine
- Outer edge of illiac crest
- Illiotibial band (which runs to superolateral aspect of tibia)- Superior gluteal nerve: L4,L5,S1- Superior gluteal artery
- Lateral circumflex femoral artery
