11: Hip Muscles Flashcards
Biceps Femoris
O: Long head=ischial tuberosity
Short head=1/2 down linea aspera
I: fibular head, lateral condyle of tibia
A: knee flexion, hip extension, hip hyperextention, hip external rotation, hip adduction
HAMSTRINGS (most lateral)
Semitendinosus
O: ischial tuberosity
I: upper medial part of shaft of tibia
A: knee flexion, hip extension, hip hyperextension, hip internal rotation, hip adduction
HAMSTRINGS (superficial)
Semimembranosus
O: ischial tuberosity
I: posterior part of the medial condyle of tibia
A: knee flexion, hip extension, hip hyperextension, hip internal rotation, hip adduction
HAMSTRINGS (deep)
Gracilis
O: inferior ramus and body of pubis
I: upper, anterior-medial surface of tibia
A: adduction, hip flexion, knee flexion
(most medial muscle of the thigh)
Adductor Magnus
O: inferior ramus of pubis, ischium
I: linea aspera, adductor tubercle of femur
A: adduction, flexion, external rotation, extension, hyperextension, internal rotation
Adductor Longus
O: anterior body of pubis
I: medial 1/3 linea aspera
A: adduction, flexion, external rotation
(medial border of femoral triangle)
Adductor Brevis
O: inferior ramus of pubis
I: upper 1/3 medial linea aspera
A: adduction, flexion, external rotation
Pectineus
O: superior ramus of pubis
I: lesser trochanter to linea aspera (pectineal line)
A: adduction, flexion, external rotation
Rectus Femoris
O: anterior head=AIIS
Posterior head= upper margin of acetabulum
I: top of patella to tibial tuberosity by patellar tendon
A: hip flexion, knee extension
QUAD (only one that crosses the hip)
Sartorius
O: ASIS
I: upper, medial part of tibia
A: hip flexion, external rotation, abduction, knee flexion
LONGEST MUSCLE IN BODY
Iliacus
O: iliac fossa
I: lesser trochanter
A: hip flexion, external rotation, adduction
“true groin muscle”
Psoas Major
O: transverse process of lumbar vertebrae
I: lesser trochanter
A: hip flexion, external rotation, adduction
“true groin mucsle”
Gluteus Medius
O: posterior surface of ilium
I: greater trochanter
A: abduction, flexion, internal rotation, extension, hyperextension, external rotation
IM injections
Tensor Fasciae Latae
O: ASIS
I: IT band
A: abduction, hip flexion, internal rotation
Gluteus Maximus
O: gluteal line of ilim, sacrum/coccyx
I: IT band
A: hip extension, hyperextension, external rotation, adduction
Gluteus Minimus
O: lower part of posterior surface of ilium
I: greater trochanter
A: abduction, internal rotation, flexion
(smallest, deepest gluteal, keeps the pelvis level)
Name the 6 external rotators, and their O, I, and A
Piriformis
Obturator Externus
Obturator Internus
Gemellus Superior
Gemellus Inferior
Quadratus Femoris
O: ischium
I: greater trochanter
A: external rotation, stabilize the femur
irritation of ITB, usually by the knee; passes over the lateral epicondyle of the femur so it is prone to friction when sliding over it back and forth
IT Band Syndrome
similar to ITB syndrome, but with greater trochanter
trochanteric bursitis
Hip extensors/flexors strength imbalance
stronger extensors than flexors
name the muscles in the hip adductor group (4)
pectineus
adductor brevis
adductor longus
and adductor magnus
femoral triangle
superior border: inguinal ligament
lateral border: sartorius
medial border: adductor longus
posterior pelvic tilit position helps with what movements
hip flexion
anterior pelvic tilt position helps with what movements
hip hyperextension movements
