  1. Anatomy Wokrshop Pelvis, hip and femur (myology 1) 분당서울대학교병원 정형외과 성기혁

  2. Anterior muscles of pelvis

  3. Psoas major Origin : T12-L5 vertebra Insertion : lesser trochanter Action : powerful hip flexion Innervation: femoral N.

  4. Psoas minor Origin : T12 & L1 vertebra Insertion : pectineal line Action : weak flexion of trunk

  5. Iliacus Origin : iliac fossa Insertion : lesser trochanter Action : powerful hip flexion Innervation: Femoral N.

  6. Gluteal muscles

  7. Origin : ilium & dorsal sacrum Insertion 1. gluteal tuberosity 2. iliotibial band Action 1. powerful extension 2. ER of hip Innervation: inferior gluteal N. Gluteus maximus

  8. Origin:ilium between anterior & posterior gluteal lines Insertion: greater trochanter Action: 1. powerful abduction 2. IR of hip 3. Balancing during walking Innervation : superior gluteal N. Gluteus medius

  9. Gluteus minimus Origin: ilium between anterior & inferior gluteal lines Insertion: anterior greater trochanter Action: 1. abduction & IR of hip 2. Assistgluteus medius during walking

  10. Trendelenburg sign

  11. Piriformis • Origin: • anterior sacrum • Insertion: superior greater trochanter • Action: • 1. hip ER • 2. hip abduction during flexion

  12. Obturator internus Origin 1. ischiopubic rami 2.obturator membrane Insertion: medial greater trochanter Action: 1. hip ER 2. hip abduction during flexion

  13. Superior & Inferior gemellus Origin: ischial spine(sup.) ischial tuberosity(inf.) Insertion: medial greater trochanter Action: 1. hip ER 2. hip abduction during flexion

  14. Quadratus femoris Origin: ischial tuberosity Insertion: intertrochanteric crest Action: hip ER

  15. Posterior femoral muscles (Hamstrings)

  16. Biceps femoris(long head) Origin: ischial tuberosity Insertion: head of fibula Action: 1. hip extension 2. knee flexion & ER Innervation: tibial division of sciatic N.

  17. Biceps femoris(short head) Origin: 1. linea aspera, 2. supracondylar line Insertion: fibula, lateral tibia Action: knee flexion & ER

  18. Semitendinosus Origin: ischial tuberosity Insertion: proximal medial tibia Action: 1. hip extension 2. knee flexion & IR Innervation: tibial division of sciatic N.

  19. Semimembranosus Origin: ischial tuberosity Insertion: posterior medial tibial condyle Action: 1. hip extension 2. knee flexion & IR Innervation: Tibial division of sciatic N.

  20. Psoas & iliacus: hip flexion Gluteus medius & minimus: hip abduction & IR Gluteus maximus & hamstrings: hip extension Piriformis & short rotators: hip ER

  21. Thank you !!
