Q

What are the contents of the popliteal fossa?

A
Popliteal artery and vein
Tibial and common fibula nerves
Terminal branch of the posterior cutaneous nerve of the thigh
Popliteal lymph nodes and vessels
Small saphenous vein
1
Q

What is the popliteal fossa?

A

A space on the posterior aspect of the knee joint
It is a passage for most of the neurovascular structures of the leg
Boundaries:
SL: biceps femoris
SM: semimembranosis and semitendonosis
IM: medial head of gastrocnemius
IL: lateral head of gastrocnemius
Roof: skin and fascia
Floor: popliteal surface of the femur, oblique popliteal ligament, popliteus muscle and fascia

2
Q

What is the difference between sural and crural?

A

Sural means calf

Crural means leg

3
Q

What is the pathway of the popliteal artery?

A

Continuation of the femoral artery, after the adductor hiatus
Passes inferiorlaterally through the popliteal fossa
Ends at the inferior border of popliteus by dividing into anterior and posterior tibial arteries

4
Q

What are the facial compartments of the leg?

A

Anterior
Posterior
Lateral

5
Q

What are the bones of the foot/ tarsal bones?

A
Talus
Calcaneus
Navicular
Cuboid
Cuneiforms
Metatarsals
Phalanges
6
Q

What are the borders of the anterior compartment of the leg?

A
Lateral surface of the tibia
Medial surface of the fibula
Interosseus membrane
Inter muscular septum
Crural fascia
7
Q

What are the contents of the anterior compartment of the leg?

A
Anterior tibial artery and vein
Deep fibulae nerve
Tibialis anterior
Extensor digitoxin longus
Extensor hallucinations longus
Fibularis tertius
8
Q

Tibial is anterior

A

O: lateral condyle of the tibia, superior half of the lateral surface of the tibia and Interosseus membrane
I: medial and inferior surface of the medial cuneiform and base of first metatarsal
NS: deep fibular nerve
A: dorks flexes ankle and dorsiflexes ankle

9
Q

Extensor digitoxin longus

A

O: lateral condyle of the tibia, superior fourth of the medial surface of the fibula, adjacent Interosseus membrane
I: extensor expansion, middle and distal phalanges of lateral 4 toes
NS: deep fibular nerve
A: extends lateral 4 digits and dorsiflexes ankle

10
Q

Extensor hallucis longus

A

O: Middle part of the anterior surface of the fibula and adjacent Interosseus membrane
I: dorsal surface of the base of the distal phalanx (first digit or big toe)
NS: deep fibula nerve
A: extends big toe and dorsiflexes ankle

11
Q

Fibularis tertius

A

O: inferior third of the anterior surface of the fibula, adjacent Interosseus membrane
I: dorsum, base of fifth metatarsal
NS: deep fibular nerve
A: dorsiflexes ankle and aids in eversion
