Anatomy: Thigh

Question 1

What is the deep fascia of the leg?

Answer 1

fascia lata

crural fascia

Question 2

Where does the fascia lata connect superiorly?

Answer 2

inguinal ligament

Question 3

What makes up the IT band?

Answer 3

fascia lata
gluteus maximus tendon
tensor FL tendon

Question 4

Where does the IT band attach?

Answer 4

patella (patellar retinaculum)

Gerdy’s tubercle of the tibia

Question 5

What are the three compartments of the leg?

Answer 5

anterior (hip flexors/knee extensors)
medial (hip adductors)
posterior

Question 6

What are the superficial veins of the leg?

Answer 6

great and small saphenous veins

Question 7

Where does the small saphenous vein go deep?

Answer 7

popliteal

Question 8

Where does the great saphenous vein go deep?

Answer 8

saphenous hiatus, just under the inguinal ligament

Question 9

What innervates the hip flexors and knee extensors?

Answer 9

femoral nerve 
(except TFL)

Question 10

Iliopsoas action and attachment?

Answer 10

lesser trochanter

hip flexion and lateral rotation

Question 11

How does a femoral neck fracture present?

Answer 11

shortened and laterally rotated leg because of iliopsoas tension

Question 12

What is the psoas sign?

Answer 12

pain on hip extension (stretching the psoas), may be a sign of psoas abscess

Question 13

What makes up the quadriceps? Innervation?

Answer 13

rectus femorus, vastus lateralis, medialis, and intermedius
femoral nerve (L2-4)

Question 14

What is Osgood-Schlatter?

Answer 14

quadriceps doesn’t let the tibial tuberosity fuse to the tibia (seen in kids)

Question 15

What are the 5 hip adductors?

Answer 15

adductor longus
adductor brevis
adductor magnus
gracilis
obturator externus

Question 16

What innervates the hip adductors?

Answer 16

obturator nerve (L2-4)

Question 17

What are the three sections of the adductor magnus?

Answer 17

adductor minimus
adductor
hamstring (innervated by sciatic nerve)

Question 18

What is the opening between the adductor portion and the hamstring portion of the adductor magnus?

Answer 18

adductor hiatus (femoral vessels)

Question 19

Where do the gracilis and sartorius insert?

Answer 19

pes anserinus of medial tibial condyle (goose foot)

Question 20

What are the 4 openings from pelvis to lower limb?

Answer 20

obturator canal
under the inguinal ligament
greater/lesser sciatic foramina

Question 21

What passes through the obturator canal?

Answer 21

obturator nerve and vessels

Question 22

What passes under the inguinal ligament?

Answer 22

muscular lacuna:
iliopsoas
femoral nerve
lateral femoral cutaneous nerve
vascular lacuna:
femoral vessels
femoral branch of genitofemoral nerve
lymphatics

Question 23

What is in the femoral triangle (lat to med)

Answer 23

nerve
artery
vein
(vessels enclosed in femoral sheath)

Question 24

What is a femoral hernia?

Answer 24

protrusion of something (usually bowel) into the femoral ring into the femoral canal

Question 25

Where is the adductor canal and what does it hold?

Answer 25

from bottom of femoral triangle to adductor hiatus
femoral vessels
saphenous nerve
nerve to vastus medialis

Question 26

What comes off of the deep femoral artery?

Answer 26

medial and lateral circumflex (to femoral head)
perforating branches (hamstrings)
