Q

What are the accessory ligaments?

A

Ligament of head of femur

17
Q

What shape is the iliofemoral ligament?

A

18
Q

What is the function of the iliofemoral ligament?

A

Protects hip superiorly + anteriorly

19
Q

What is the function of the pubofemoral ligament?

A

Protects hip anteriorly + inferiorly

Prevents over abduction

20
Q

What is the function of the ischiofemoral ligament?

A

Limits extension

21
Q

What is the function of the transverse acetabular ligament?

A

Stabilises the head of the femur

22
Q

What is the function of the ligament of head of femur?

A

Stabilises head of the femur

Prevents excessive abduction

23
Q
