Flashcards in Muscles of medial thigh Deck (11):

Adductor brevis

origin: inferior ramus of pelvis
Insertion: pectineal line + medial lip of linea aspera (femur)
action: adduction, flexion, extension, internal rotation, stabilise pelvis
nerve: obturator nerve (L2-L3)
artery: obturator artery + deep femoral artery


what would injury to obturator nerve result in and why? where would the injury normally be?

weakened adduction as the obturator nerve supples the adductor muscles
normally injury to pelvis


adductor longus

origin: medial part of superior ramus of pubis
insertion: linea aspera of femur
action: adduction,flexion (both of hip), extension, internal rotation (of femur)
nerve: obturator nerve (L2-L4)
artery:obturator artery, deep femoral artery


adductor magnus

origin: inferior ramus of pubis, ischiopubic ramus, ischial tuberosity
insertion: medial lip of aspera, adductor tubercle of femur
action: adduct, extend, weak flexion, internal rotation, stabilise pelvis
nerves: obturator nerve + tibial nerve
artery: obturator artery, deep femoral artery, branches of medial circumflex femoral artery



origin: pubic symphysis, inferior pubic ramus
insertion: proximal medial surface of tibia
action: adductor + flexion (of hip), flexion + internal rotation of knee
nerve: obturator nerve (L2-L3)
artery: obturator artery


obturator externus

origin: superior + inferior pubic rami, outer surface of obturator membrane
insertion: trochanteric fossa of the femur
action: adduction, lateral rotation of hip joint
nerve: obturator nerve (L2-L3)
artery: obturator artery



origin: pectin pubis
insertion: pectineal line of femur
actions: adduct, internal rotation, weak flexion (all of hip joint), stabilise pelvis
nerve: femoral nerve (L2-L4), obturator nerve (L2-L3)
artery: branches of medial circumflex femoral artery


What are muscles of the medial compartment of the thigh collectively known as?

hip adductors (bring legs back in from the side)


what is injury to the adductor muscles? what is it known as?

strain of the adductor muscles (medial compartment)
'groin strain'


Which muscles are affected in 'groin strain'? How come?

Proximal part of the muscles
tearing near the bony attachments in the pelvis (pelvis being the proximal attachment)


What treatment is used for injury to adductor muscles 'groin strain'

RICE protocol
rest, ice, compression, elevation
