Question 1

Femoral triangle is made up of what?

Answer 1

Medial: adductor longus

Superior: inguinal triangle

Contains the femoral nerve, artery, vein and lymphatic (NAVL) in the femoral sheath

Question 2

Answer 2

Through the adductor canal to the adductor hiatus into the posterior popliteal fossa

Question 3

3 divisions of the femoral health

Answer 3

Lateral: contains femoral branch of genitofemoral

Intermediate: femoral vein

Medial: femoral ring opening fro fat and lymphatics

Question 4

Saphenous opening

Answer 4

Passage of the greater saphenous vein from superifical to deep fascia and then meets up with femoral vein

Question 5

What vein is most used for arterial bypass?

Answer 5

Saphenous vein

Question 6

Location of saphenous cutdown

Answer 6

Anterior to the medial malleolus. Can insert cannula drugs

Question 7

Obturator artery

Answer 7

Gives rise to acetabular branches which supply the femoral head and acetabulum.

Question 8

Femoral artery branches

Answer 8

Deep femoral

Lateral/medial circumflex femoral

Perforating branches

Question 9

Answer 9

5 genicular branches

Superior medial and lateral genicular

Inferior medial and lateral genicular

Middle genicular

Question 10

Anterior tibial artery supplies what

Answer 10

Anterior leg, dorsal foot

Question 11

Posterior tibial artery supplies what?

Answer 11

Posterior and lateral leg, soles of foot

Question 12

Gluteus Maximus action and innervation

Answer 12

Extends and lateral rotation of thigh

Inferior gluteal nerve

Question 13

Piriformis action and innervation

Answer 13

Abduct flexed thigh and lateral rotation of thigh

Nerve to piriformis

Question 14

Gluteus medius, minimus and tensor fascia lata

Answer 14

Abduction, medial rotation and prevents pelvic drop

Superior gluteal nerve

Question 15

Obturator internus and gemellus superior

Answer 15

Abudcts thigh and lateral rotates

nerve to obturator internus

Question 16

Quadratics femoris and gemellus inferior actions and innervation

Answer 16

Abucts flexed thigh and laterally rotates

Nerve to quadratus femoris

Question 17

What structures are at risk for an intramuscular injections of butt?

Answer 17

Superior gluteal artery and nerve, sciatic nerve

Question 18

Piriformis syndrome

Answer 18

Compression of sciatic nerve by the piriformis usually through hypertrophy. Also common fibular nerve is disrupted also

-usually affects dorsiflexion and eversion

Question 19

Answer 19

Inversion

Question 20

If the tendons attach to the medial side of the leg what does it help?

Answer 20

Eversion
