Anatomy of the Hip and Pelvis Flashcards
Adductor brevis?
Body of pubis/inferior pubic ramus
Pectineal line of femur/proximal 1/3 medial lip Linea aspera
Adducts thigh at hip joint
Adductor Longus?
Anterior body of pubis
Middle 1/3 linea aspera
Adducts thigh at hip
Biceps femoris?
long head=ischial tuberosity
short head= linea aspera/lateral supracondylar line
head of fibula
extends thigh at hip joint
gemellus inferior?
ischial tuberosity
medial aspect greater trochanter of femur
lateral rotation/ transverse abduction
gemellus superior?
ischial spine
medial aspect greater trochanter of femur
lateral rotation/ transverse abduction
gluteus maximus?
ilium posterior to posterior gluteal line/ posterior sacrum&coccyx aspect/ sacrotuberous ligament
tubercle of iliotibial tract of tibia/gluteal tuberosity of femur
extension/lateral rotation/abduction
gluteus medius?
ilium between anterior/posterior gluteal lines
lateral aspect greater trochanter
medial rotation/abduction
gluteus minimus?
ilium (between anterior/inferior gluteal lines)
anterolateral aspect of greater trochanter
medial rotation/ abduction
gracilis?
body of pubis/inferior pubic ramus
medial proximal tibia
assists adduction
iliacus?
iliac crest/superior 2/3 iliac fossa/ ala of sacrum/ anterior sacroiliac ligaments
lesser trochanter femur via tendon of psoas major
flexes hip/ flexes trunk
obturator externus?
external surface obturator membrane
trochanteric fossa of femur
lateral rotation
obturator internus?
internal surface obturator membrane
medial aspect of greater trochanter
lateral rotation/transverse abduction
pectineus?
superior pubic ramus
pectineal line of femur
adduction/flexion
piriformis?
pelvic surface of sacrum/ sacrotuberous ligament
superior border of greater trochanter
lateral rotation/transverse abduction
psoas major?
transverse processes l1-l5/ vertebral bodies t12-l5
lesser trochanter
flexion of hip/trunk
quadratus femoris?
lateral margin of ischial tuberosity
quadrate tubercle of femur
lateral rotation
rectus femoris?
anterior inferior iliac spine/ supraacetabular groove of ilium
tibial tuberosity via common quad tendon
flexion
sartorius?
anterior superior iliac spine
medial aspect proximal tibia
flexion/ abduction/ lateral rotation
semimembranosus?
ischial tuberosity (with long head BF)
medial condyle of tibia
extension
semitendinosus?
ischial tuberosity
medial aspect proximal tibia
extension
tensor fascia latae?
anterior super iliac spine/ anterior 1/3 outer lip iliac crest
tubercle of iliotibial tract of tibia
medial rotation, abduction, flexion
ilio-femoral joint?
ball and socket
head of femur + acetabulum of pelvis
F/Ex/Ab/Add/MR/LR
ligament of head of femur (intracapsular)
Iliofemoral ligament (Extracapsular)
Pubofemoral (Extracapsular)
Ischiofemoral (Extracapsular)
pubic syphysis?
cartilaginous joint
left pubis + right pubis
connects ligament of penis in males/opens during birth in women (above clitoris)
SI joints?
sacrum + ilium
limited motion but strong ligaments protect L5-S1
control/distribute forces from body to legs
shock absorber to spine
allow walking, spinal and thigh movements
widen during childbirth
