The following muscles are called hip adductors.
Adductor longus and adductor brevis
Adductor Magnus
Gracilis
1. Adductor longus and adductor brevis
-origin -anterior pubis
-insertion- linea aspera on posterior femur
Nerve supply- obturator(l3,4)
Action- adduction of femur at the hip, assist flexion and medial rotation pf femur at the hip
Palpation – adductor longs-prominent cord-like origin at media aspect of groin during active adduction of hip
-adductor brevis-may attempt to palpate laterally to adductor longus origin on the pubis.
Adductor longus forms the medial border of the femoral triangle.
Adductor Magnus
-origin- pubic ramus, ischial tuberosity, and ramus
-insertion- linea aspera of posterior femur, adductor tubercle of medial femur
-nerve supply- anterior -obturator nerve(l2,3,4)
-posterior-sciatic nerve(l4,5,s1,2,3)
Action- adduction of the femur at hip joint, assist medial rotation of femur at hip, anterior fibers assist flexion of the femur at hip, posterior fibers assist Extention of femur at hip
Palpation- surface of thigh just medial to gracilis during active adduction of hip.tendon palpated at its insertion on the adductor tubercle
Adductor hiatus – emergence of femoral artery and femoral vein to poplitial fossa behind knee.
3. Gracilis
-origin- anterior pubis
-insertion- medial proximal tibia
-nerve supply- obturator nerve(l2,3,4)
Action- adduction of femur at hip ,assist flexion and medial rotation of flexed knee
-palpation- a few inches below pubic bone on medial side of thigh during active hip adduction.tendon palpated on medial side of posterior knee ,medial to semitendinosus tendon
-this is the most superficial and medial of the adduxtors .the femoral shaft and the gracilis form tge shape of the letter 'v'.
