1.2.3. Neurovascular Supply of the Hip Joint

Question 1

What are the main Arteries which supply the Hip Joint?

Answer 1

1. Medial Circumflex Femoral Artery
2. Lateral Circumflex Femoral Artery

Question 2

What are the Medial and Lateral Circumflex Femoral Arteries a branch of?

Answer 2

Profunda Femoris Artery (A deep Femoral Artery)

Question 3

What happens to the Medial and Lateral Circumflex Femoral Arteries at the Base of the Femoral Neck?

Answer 3

They Anastomose

Question 4

As the Medial and Lateral Circumflex Femoral Arteries Anastomose, what is formed?

Answer 4

A Ring

Question 5

How does the Ring, formed by the Anastomosis of the Medial and Lateral Circumflex Femoral Arteries, supply the Hip Joint?

Answer 5

Smaller Arteries arise from this Ring, which supplies the Hip Joint

Question 6

Which Artery is mainly responsible for the majority of the Arterial supply to the Hip Joint?

Answer 6

The Medial Circumflex Femoral Artery

Question 7

Why is the Medial Circumflex Femoral Artery responsible for the majority of the Arterial supply to the Hip Joint?

Answer 7

The Lateral Circumflex Femoral Artery needs to penetrate through the thick Iliofemoral Ligament

Question 8

What can damage to the Medial Circumflex Femoral Artery result in?

Answer 8

Avascular Necrosis of the Femoral Head

Question 9

What Arteries also provide additional Arterial supply to the Hip Joint?

Answer 9

1. The Artery to the Head of the Femur
2. The Superior Gluteal Artery
3. The Inferior Gluteal Artery

Question 10

Which Nerves (4) innervate the Hip Joint?

Answer 10

1. The Femoral Nerve
2. The Obturator Nerve
3. The Superior Gluteal Nerve
4. The Nerve to the Quadratus Femoris
