19
Q

What are the 2 internal ligaments of the hip joint?

A

Transverse acetabular ligament

Ligament of head of femur

20
Q

Which internal ligament of the hip spans the acetabular notch?

A

Transverse acetabular ligament

21
Q

Which internal ligament of the hip joint contains an artery to the head of the femur and is covered by synovial membrane?

A

Ligament of head of femur

22
Q

What are the external ligaments of the hip joint?

A

Iliofemoral ligament
Ischiofemoral ligament
Pubofemoral ligament

23
Q

What is the most important of the femoral ligaments?

A

Iliofemoral ligament - it is one of the strongest ligaments in the body

It screws the femoral head into the acetabulum when standing, and prevents hyperextension

24
Q

The iliofemoral ligament is located _______ and ________

Anterior/posterior vs. superior/inferior

A

Anteriorly; superiorly

25
Q

Which external ligament of the hip joint is located anteriorly and inferiorly and blends with the medial iliofemoral ligament?

A

Pubofemoral ligament

26
Q

What is the primary function of the pubofemoral ligament?

A

Tightens during extension and abduction of the thigh, prevents overabduction

27
Q

What external ligament of the hip joint is located posteriorly and spirals superolaterally to the femoral neck?

A

Ischiofemoral ligament

28
Q

What nerves provide sensation in the hip joint?

A

Sensory branches of:

Gluteal n.
Obturator n.
Femoral n.

29
Q

What group of blood vessels provides the arterial supply to the hip joint?

A

Cruciate anastomosis

30
Q

What arteries are included in the cruciate anastomosis?

A 
Medial femoral circumflex a.
Lateral femoral circumflex a.
Inferior gluteal a.
First perforating artery of profunda femoris a.
Obturator a.
