What is the gracilis function?

A

Adductor, knee & hip flexor

21
Q

What are the divisions of the obturator nerve?

A

Anterior - above the adductor brevis

Posterior - behind adductor brevis

22
Q

Where doe the hamstring part of the adductor magnus originate?

A

Ischial tuberosity

23
Q

When does groin pull usually happen - what muscles?

A

Adductor muscles - sports that require quick starts - short distance running

24
Q

What artery supplies the head of the femur?

A

Branch of the obturator artery

25
Q

In adults the ___ provides imp. blood supply to the femoral head.

A

MFC - Medial femoral circumflex artery

26
Q

What innervates the anterior compartment of the leg?

What innervates the lateral compartment of the leg?

A

Deep fibular nerve

Superficial fibular nerve (underneith the fibularis longus)

27
Q

What is the function of the tibialis anterior?

A

It dorsiflexes the foot & inverts the foot

28
Q

What is the function of the fibularis tertius?

A

It dorsiflexes the foot & helps in eversion

29
Q

What are the functions of the extensor hallicus longus & extensor digitorum longus?

A

Extending toes & dorsiflexing the foot

30
Q

What is “Ski Boot Syndrome”?

A

It is deep fibular nerve entrapment - often caused by too tight of a shoe on people wiht high arches - produces pain that radiates to the first and second toes

31
Q

What are the “P signs” of peripheral artery disease/arterial occlusion?

A

Pain, pallor (unhealthy, pale appearance), paresthesia, paralysis & Pulselessness

32
Q

What causes foot drop? Or the inability to dorsiflex and evert the foot?

A

Damage to the common fibular nerve!! (can no longer dorsiflex)

33
Q

What supplies the lateral compartment of the lower leg?

A

Superficial fibular nerve

34
Q

What are the functions of the fibularis longus & brevis?

A

Eversion & weak plantarflexion

Where does fibularis longus insert?

A

The base of the first metatarsal (wraps underneath the foot)

36
Q

What artery supplies the lateral compartment of the leg?

A

The fibular artery

37
Q

Where do meniscal tears heal best?

A

At the periphery – generous blood supply here!

38
Q

What is the “unhappy triad”?
