Q

What is the strongesr campsule ligament

A

Iliofemoral

18
Q

What is the weakest capsule ligament

A

Ischiofemoral

19
Q

What is the function of the iliofemoral

A

Resists extensive extension of the hip joints

20
Q

What is the function of the pubofemoral ligament

A

Support the hip joint inferiorly

21
Q

Function of the Ischiofemoral joint

A

Protects the joints posteriorly, and resists excessive flexion of the hip joint

22
Q

The ligament of the head of the femur

A

Connects the head of the femur to the transverse femoral ligament

23
Q

Which ligament of the hip joint does not play a role in the stability of the joint

A

The ligament of the head of the femur

24
Q

Which muscles in the lower limb can be likened to the rotator cuff muscles

A

Piriformis, obturator internis gemelli

25
Q

What nerve can be affected when the hip joint dislocates posteriorly

A

The sciatic nerve

26
Q

What is the main arterial blood supply of the hip joint

A

Retinacular arteries

27
Q

Which arteries do the Retinacular arteries branch from

A

Medial and lateral circumflex femoral artery

28
Q

What is trochanteric anastomosis

A
29
Q

Which other artery supplies the head of the

A

Artery to the head of the femur

30
Q

What year does the artery to the head of the femur obliterate

A

7 years

31
Q

Why are sickle cell patients likely to have avascular necrosis of the head of the femur

A

Because the artery to the head of the femur closes even earlier than the average 7 years
At this stage, the Retinacular arteries are not fully developed hence the loss of blood supply to the head of the femur

32
Q

What is the major muscle for the flexion of the hip joint

A

Iliopsoas( Iliacus and Psoas major muscle

33
Q

What is the major muscle for the Extension of the hip joint

A

The gluteus maximus

34
Q

What is the major muscle for the Abduction of the hip joint

A

The gluteus medius and minimus

35
Q

What is the biggest synovial joint in the body

A

The knee joint

36
Q

Why is the knee joint considered compound synovial joint

A

Because its formed by two bones

37
Q

The knee joint is considered to be a modified himge joint

Why is this so

A

Becaus eit allows other movements apart from flexion and extension so its not a true hinge joint

38
Q

Origin and insertion of the patella ligament

A

Extends from the apex of the of the patella to the tibial tuberositty

39
Q

What forms the patella retinaculum

A

Ligaments of the vastus lateralis and medialis

40
Q

Genu varos posit
