Q

The flexor retinaculum holds down these structures on the medial mallelus

A
  • Tendons of the posterior compartment
  • Tibial Nerve
  • Posterior tibial artery
23
Q

What is the main action of the lateral compartment

A

Evertors

24
Q

What are the boundaries of the lateral compartment

A
  • Fibula

- Anterior and poster intermuscular septa

25
Q

Where does the lateral compartment end?

A

Superior fibular retinaculum

26
Q

What is compartment syndrome?

A

When you have inflammation, edema, hemorrhage and this leads to high pressures in the closely packed compartments

27
Q

What are the borders of the popliteal fossa

A

Superolaterally=Biceps femorus m
Superomedially= Semimembranosus m
Inferomedially=Medial head of gastroc
Inferolaterally= Lateral head of gastroc

28
Q

What is the roof over the popliteal fossa

A

-Skin and deep fascia

29
Q

What are the bony landmark borders of the popliteal fossa

A
  • Supracondylar lines of the femur
  • Popliteal surface of the femur
  • Soleal line of the tibia
  • Popliteus muscle
  • Posterior capsule of knee
30
Q

What are the contents of the popliteal fossa

A
  • Termination of small saphenous vein (turns to popliteal vein)
  • Popliteal vein and artery
  • Tibial and common fibular nerves
  • POsterior cutaneous nerve of the thigh
  • Lymph nodes
  • Vessels
  • Fat
31
Q

This artery travels anteromedially through the thigh and it changes its name after reaching the adductor hiatus

A

Femoral artery –> Popliteal artery

32
Q

Does the popliteal artery run deep or superficial in the popliteal fossa?

A

Deep

33
Q

What does the popliteal artery give rise to?

A

-5 genicular arteries (anastomoses of the knee joint)

34
Q

Where and what does the popliteal artery divide into?

A

At the inferior border of the popliteus it divides in to the anterior and posterior tibial artery

35
Q

This is the artery for the anterior compartment

-passes through a gap in the interosseosu membrane to get there

A

Anterior tibial artery

36
Q

What are where does the anterior tibial aerty change into?

A
  • Distal to the inferior extensor retinaculum

- Becomes the dorsal artery of the foot (dorsus pedus)

37
Q

This is the more direct continuation of the popliteal artery

-The artery of the posterior compartment

A

Posterior tibial artery

38
Q

What does the posterior tibial artery supply

A

All the arteries of the posterior compartment

39
Q

Where and what does the posterior tibial artery divide into?

A
  • Distal to the flexor retinaculum

- Medial and lateral plantar arteries

40
Q

This is a branch of the posterior tibial artery and it runs lateral and parallel to the posterior tibial artery

A

Fibular artery

41
Q

What does the fibular artery supply?

A

Muscles of the posterior compartment and the lateral compartment via perforating branches

42
Q

What is the layout of the 5 geniculate arteries

A
  • Superolateral
  • Superomedial
  • Inferolateral
  • Inferomedial
  • Middle
43
Q

What are the arteries that participate in the knee anastomoses

A
  • Branches of the femoral and lateral circumflex femoral arteries
  • Descending genicular
  • Descending branch
  • Anterior tibial recurrent
44
Q

What does the sciatic nerve divide into

A
  • Tibial (medial and larger)

- Common fibular (smaller and lateral)

45
Q

This nerve bisects the fossa and gives branches to the superficial posterior muslces and the popliteus

A

Tibial nerve

46
Q

What are the cutaneous branches that come off of the tibial nerve

A

-The medial sural cutaneous nerves

47
Q

What gives off the lateral sural nerve

A

The fibular nerve

48
Q

The medial and lateral sural nerves join together and become the…

A

Sural nerve

49
Q

What does the sural nerve innervate

A

The skin on the lateral side of the leg and ankle

50
Q

The tibial nerve continues and travels with the posterior tibial artery to become the…

A

medial and lateral plantar nerves (distal to the flexor retinaculum

51
Q

This nerve passes superficially to the lateral gastroc head and posterior fibular head

A

Common fibular nerve

52
Q

The common fibular nerve winds around the fibular head and divides into…

A
  • Superficial fibular nerve

- Deep fibular nerve

53
Q

The superficial fibular nerve supplies…

A
  • Muscles of the lateral compartment

- Skin on the distal 1/3 of the anterior surface of the leg and the majority of the dorsum of the foot

54
Q

What does the deep fibular nerve innervate

A
  • Descends on the surface of the interosseous membrane and supplies the anterior compartment muscles
  • Dorsum of the foot
  • Skin between first and second toes
