Hip joint

Question 1

Does medial rotation of the femur move the greater trochanter forwards or backwards?

Answer 1

Forwards

Question 2

What are the articular surfaces of the hip joint?

Answer 2

The femoral head and the lunate surface of the acetabulum

Question 3

What is raised from the rim of the acetabulum?

Answer 3

The acetabulum labrum.

Question 4

What does the acetabulum labrum form …ly?

Answer 4

The transverse acetabular ligament inferiorly.

Question 5

What is the other name for ligament of head of femur?

Answer 5

The ligamentum teres.

Question 6

What ligament attaches the fovea to the acetabular fossa, acetabular notch margins, and the transverse acetabular ligament?

Answer 6

The ligament of head or femur.

Question 7

What artery does the ligament of the head of femur carry?

Answer 7

The obturator artery.

Question 8

What are the three ligaments of the hip joint?

Answer 8

The iliofemoral ligament, the pubofemoral ligament, and the ischiofemoral ligament.

Question 9

True or false?

The iliofemoral ligament is anterior to the hip joint.

Answer 9

True

Question 10

What does the iliofemoral attach to? (both ilium and the femur)

Answer 10

In the ilium, it is located between AIIS and the acetabulum.

In the femur, it is located between the intertrochanteric line.

Question 11

True or false?

The iliofemoral ligament is M-shaped

Answer 11

False, the iliofemoral ligament is Y shaped since the middle part of the intertrochanteric line aspect of the iliofemoral ligament is thinner.

Question 12

True or false?

The pubofemoral ligament is separate with the fibrous membrane of the hip joint and the deep surface of the iliofemoral ligament.

Answer 12

False, it is continuous

Question 13

What are the attachments of the ischiofemoral ligament on the femur?

Answer 13

The greater trochanter deep to the iliofemoral ligament.

Question 14

What are the 4 gateways that connect the pelvic region to the lower limb?

Answer 14

1. The obturator foramen - connect pelvis and the medial thigh
2. The gap between inguinal ligament and the pelvis
3. The greater sciatic foramen
4. The lesser sciatic foramen

Question 15

True or false?

The lesser sciatic foramen is divided into two parts.

Answer 15

False, the greater sciatic foramen is

Question 16

What are the relations of the lesser sciatic foramen?

Answer 16

The lesser sciatic foramen is located inferior to the levator ani and coccygeus muscles.

Answer 21

• Obturator internus muscle tendon
• Pudendal nerve and internal pudendal
  vessels pass into perineum
  from gluteal region

Question 22

What foramen does the obturator internus pass through?

Answer 22

The lesser sciatic foramen
