A

medial malleoulus

34
Q

How does the tibial nerve and posterior tibial artery enter the foot?

A

through the tarsal tunnel medially

35
Q

A

bifricate

36
Q

What will the posterior tibial artery bifricate into in the foot?

A

medial and lateral plantar arteries

37
Q

In the proximal leg the posterior tibial artery will give off what artery? this occurs before entering the feet*

A

fibular artery

38
Q

41
Q

What is the branch that comes off the internal iliac artery?

A

obturator artery

42
Q

What is the branch that comes off the obturator artery?

A

acetabular branch artery

43
Q

What is the acetabular branch aka?

A

artery to ligamentum teres

44
Q

Where does the acetabular/artery to ligamentum teres travel within?

A

within the ligamentum teres

45
Q

Where does the acetabular/artery to ligamentum teres end up after traveling thorugh the ligamentum teres?

A

femoral head

46
Q

What is the artery that is the major blood supply to the femoral head in the early life?

A

acetabular artery

47
Q

As we age what happens to the perfusion of the femoral head?

A

majority starts as acetabular artery, as we age this blood supply becomes secondary. Circumflex femoral arteries become primary.

Q

Many elder people don’t get perfusion to what area of the body, and only is found out when it is fractured?

A

artery to ligamentum teres, sometimes leading to avascular necrosis of the femoral head
