Answer 1

hip

Question 2

Answer 2

Anterior

Question 3

Answer 3

Lateral

Question 4

When the trunk extends what does the sacrum do?

Answer 4

flex

Question 5

When the trunk flexes what does the sacrum do?

Answer 5

extend

Question 6

Which nerves and vessels supply the region from the abdomen to the anterior thigh?

Answer 6

Femoral vessels and nerves

Question 7

Which nerves and vessels supply the region from the pelvis to the gluteal?

Answer 7

Superior and inferior gluteal nerves and vessels

Question 8

Which nerves and vessels supply the region from the pelvis to the medial thigh?

Answer 8

Obturator nerves and vessels

Question 9

The stability of the hip joint is dependent on what 3 things?

Answer 9

• Depth of socket
• Strength of joint capsule
• Attachment of muscles crossing joint

Question 10

What 2 structures are located in the hip socket?

Answer 10

• Acetabular labrum

- Transverse acetabular ligament

Question 11

Which ligament is a major player in the strength of the joint capsule?

Answer 11

Iliofemoral ligament (Y ligament)

Question 12

Why is the iliofemoral ligament also called the Y ligament?

Answer 12

The shape of the inverted Y attaches the AIIS and acetabular rim to intertrochanteric line

Question 13

The iliofemoral ligament reinforces the fibrous capsule in what direction?

Answer 13

anterior

Question 14

The iliofemoral ligament resists which movements at the hip while standing?

Answer 14

Hyperextension and lateral rotation

In other words it supports the trunk on the lower limb

Question 15

Where does the iliofemoral ligament insert at?

Answer 15

the intertrochanteric line

Question 16

What is the second ligament that reinforces the joint capsule?

Answer 16

Ischiofemoral Ligament

Question 17

The ischiofemoral ligament reinforces the fibrous capsule in what direction?

Answer 17

posterior

Question 18

The iliofemoral ligament resists which movement at the hip while standing?

Answer 18

hyperextension

Question 19

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

Answer 19

Connects acetabular rim and transverse ligament with head of femur

Question 20

What mnemonic can be used to remember the boundaries of the femoral triangle?

Answer 20

SAIL

• Sartorius
• Adductor longus
• Inguinal Ligament

Question 21

What mnemonic can be used to remember what is located in the femoral triangle?

Answer 21

NAVEL

• Nerve
• Artery
• Vein
• Empty scape
• Lymph nodes

Question 22

What is the natural angle of inclination in the hip joint?

Answer 22

125 degrees

Question 23

If the angle of inclination is less than 125 degrees what is it called?

Answer 23

Coxa Vara

Question 24

What is the result of coxa vara?

Answer 24

The limb is shortened which means the abductors are more effective. It also puts less load on the femoral head more load on the femoral neck

Question 25

If the angle of inclination is greater than 125 degrees what is it called?

Answer 25

Coxa Valga

Question 26

What is the result of coxa valga?

Answer 26

The limb is lengthened which means the adductors are more effective. It also puts more load on the femoral head less load on the femoral neck

Question 27

Which muscles maintain pelvic height?

Answer 27

The abductors and adductors work in pairs to | maintain pelvic height and levelness

Question 28

Stability of the hip depends on what when a leg is raised?

Answer 28

Actions of the gluteus medius and minimus

Question 29

If the gluteus medius and minimus are weak what is the result?

Answer 29

The hip on the unsupported side sinks down so compensation comes from same side trunk bending which reduces torque. This also causes the hip adductors to eccentrically contract

Question 30

What is Trendelenburg’s Sign?

Answer 30

Disorder found in people with weak or paralyzed abductor muscles of the hip (gluteus medius and minimus) which results in waddling or gluteal gait

Question 31

What nerve is damaged when someone tests positive for Trendelenburg's Sign?

Answer 31

Superior Gluteal Nerve
