Anatomy: Thigh Flashcards
What is the deep fascia of the leg?
fascia lata
crural fascia
Where does the fascia lata connect superiorly?
inguinal ligament
What makes up the IT band?
fascia lata
gluteus maximus tendon
tensor FL tendon
Where does the IT band attach?
patella (patellar retinaculum)
Gerdy’s tubercle of the tibia
What are the three compartments of the leg?
anterior (hip flexors/knee extensors)
medial (hip adductors)
posterior
What are the superficial veins of the leg?
great and small saphenous veins
Where does the small saphenous vein go deep?
popliteal
Where does the great saphenous vein go deep?
saphenous hiatus, just under the inguinal ligament
What innervates the hip flexors and knee extensors?
femoral nerve (except TFL)
Iliopsoas action and attachment?
lesser trochanter
hip flexion and lateral rotation
How does a femoral neck fracture present?
shortened and laterally rotated leg because of iliopsoas tension
What is the psoas sign?
pain on hip extension (stretching the psoas), may be a sign of psoas abscess
What makes up the quadriceps? Innervation?
rectus femorus, vastus lateralis, medialis, and intermedius femoral nerve (L2-4)
What is Osgood-Schlatter?
quadriceps doesn’t let the tibial tuberosity fuse to the tibia (seen in kids)
What are the 5 hip adductors?
adductor longus adductor brevis adductor magnus gracilis obturator externus
What innervates the hip adductors?
obturator nerve (L2-4)
What are the three sections of the adductor magnus?
adductor minimus
adductor
hamstring (innervated by sciatic nerve)
What is the opening between the adductor portion and the hamstring portion of the adductor magnus?
adductor hiatus (femoral vessels)
Where do the gracilis and sartorius insert?
pes anserinus of medial tibial condyle (goose foot)
What are the 4 openings from pelvis to lower limb?
obturator canal
under the inguinal ligament
greater/lesser sciatic foramina
What passes through the obturator canal?
obturator nerve and vessels
What passes under the inguinal ligament?
muscular lacuna: iliopsoas femoral nerve lateral femoral cutaneous nerve vascular lacuna: femoral vessels femoral branch of genitofemoral nerve lymphatics
What is in the femoral triangle (lat to med)
nerve
artery
vein
(vessels enclosed in femoral sheath)
What is a femoral hernia?
protrusion of something (usually bowel) into the femoral ring into the femoral canal
Where is the adductor canal and what does it hold?
from bottom of femoral triangle to adductor hiatus
femoral vessels
saphenous nerve
nerve to vastus medialis
What comes off of the deep femoral artery?
medial and lateral circumflex (to femoral head) perforating branches (hamstrings)
