• Abduction: gluteus medius/minimus

• Adduction: adductor magnus

• Medial/Internal Rotation: gluteus medius/minimus

• Lateral/External Rotation: piriformins, gemelli, obturators

KNEE/ANKLE Prime Movers

Multiple Select

Which muscles insert into the iliotibial band? [can select multiple]

• gluteus medius

• vastus lateralis

• tensor fascia latae

• gluteus maximus

• sartorius

IT band

Gluteus medius and vastus lateralis are deep to the IT band.

IT band originates from the lateral edge of the iliac crest just superior to ASIS and inserts on the lateral epicondyle of the femur.

Multiple Choice

Which of these ligaments is most important for hip stability?

• round ligament

• pubofemoral ligament

• iliofemoral ligament

• ischiofemoral ligament

Open Ended

Why does intracapsular fracture of the head of femur almost always require replacement in patients over 60?

Blood Supply to Head of Femur

The "artery to the head of femur" is a branch of the obturator a. and reaches the head of the femur through the round ligament/ligament to head of femur. This artery is obliterate by the age of 60 in most patients.

The other supply of blood to the head of the femur are the retinacular arteries which reach the head through the joint capsule.

If there is an intracapsular fracture in a patient over 60, they lose both sources of blood to the head of the femur [artery to head of femur is obliterated AND the connection to the retinacular aa. is severed] which will cause necrosis of the head of the femur.

Multiple Choice

All of the following veins drain directly into the femoral vein except...

• popliteal v.

• great saphenous v.

• small saphenous v.

• all of the above drain into the femoral v.

Superficial Veins of Lower Leg

Great saphenous v:

- receives blood from medial and dorsal foot

- drains into femoral v.

(femoral triangle)

Small saphenous v:

- receives blood from lateral and plantar foot

- drains into popliteal v.

(popliteal fossa)

Open Ended

What are the contents of the femoral triangle?

Femoral Triangle contains:

femoral n. + femoral sheath

• 
  

• femoral sheath contains (lateral to medial):
  

• femoral a., femoral v, femoral canal
  

• femoral canal contains: 

• lymph vessels and accessory obturator a.

A soccer player takes a slide tackle to the left shin from his front-left side... which ligaments of the knee are most likely to be injured? [can select multiple]

• ACL

• PCL

• LCL

• MCL

Intra vs. Extracapsular Ligaments

• Intra = 2 ligaments [ACL, PCL], 2 meniscii [medial and lateral]

• Extra = 5 ligaments [patellar, LCL, MCL, arcuate popliteal, oblique popliteal]

Posterior Drawer Test

push tibia posteriorly

+ = PCL tear

Anterior Drawer Test

pull tibia anteriorly

+ = ACL tear

Multiple Choice
